Grand Seiko Spring Drive Chronograph GMT

  1. Running on caliber 9R86, it features a vertical clutch and column wheel design and an accuracy rating of +-15 seconds per month (which extends to the elapsed time), making it the world’s most accurate spring-driven chronograph. In addition to the chronograph feature, which can measure elapsed time up to 12 hours, Grand Seiko also included a GMT complication for even more functionality. Altogether, caliber 9R86 has more than 400 parts, and each movement is hand assembled by the skilled craftsmen and women of the Shinshu Watch Studio.
    Today, Grand Seiko is unveiling reference SBGC240, the latest addition to their Grand Seiko Spring Drive chronograph lineup and a limited edition honoring Seiko founder Kintaro Hattori and the 140th anniversary of the company he started. Those familiar with Grand Seiko’s chronograph lineup will likely see some notable design changes here. Let us first turn to the bezel. The base of the bezel features a distinct dodecahedron shape, and it’s rendered in 18k yellow gold. The outer section of the bezel is zirconia ceramic. It is worth noting that this is a solid piece of ceramic and not simply an insert. It’s fixed, colored in black, and features a highly-legible tachymeter scale, the latter detail lending to the sporty look of the watch. Another noteworthy change is the redesign of the chronograph pushers. They’ve been scaled down in size, and they’re no longer screw down like they are on references SBGC201, SBGC203, and SBGC205. The goal was to streamline the design without sacrificing any functionality (the case is rated to 10 bar) or ease of use. Like the bezel, the pushers and the crown are done in 18k yellow gold. The case, measuring 43.8mm across and 16.1mm thick, boasts a beautiful mix of finishing. The top surfaces are given a hairline finish, and the sides are polished to a distortion-free reflection only achievable through Grand Seiko’s Zaratsu method. Around back, an exhibition case back shows off the stunning 9R86 caliber. Chronograph functionality is arranged in an incredibly legible way on the dial. A 30-minute register is positioned around two o’clock, a twelve-hour register below that at four, and an active seconds hand is placed at nine. Additionally, there is a power reserve indicator around seven. A GMT hand allows for tracking a second time zone. The dial is black, and it features gold-tone accents throughout. The chronograph second hand is rendered in silver, color-matching the hands on the two chronograph counters.
    Reference SBGC240 is paired with a five-link stainless steel bracelet featuring a three-fold clasp with push button release. The clasp features an 18k yellow gold emblem marked with “GS.” Additionally, the watch comes with a crocodile strap with gold-tone stitching.

Grand Seiko Sport Mechanical Hi-Beat 36000 200m diver

Grand Seiko has just unveiled their two newest recreational diver’s watches, SBGH289 and SBGH291. These two additions to the Sport Collection feature Grand Seiko’s Hi-Beat 36000 movement, caliber 9S85, which has 37 jewels and boasts an accuracy rating of +5 to -3 seconds per day and a power reserve of 55 hours.

Grand Seiko’s recreational Grand Seiko diver’s watch is an essential tool putting precision, durability, and ease of use at the forefront, offering everything a diver needs while eschewing any distracting or superfluous adornment. Case in point, the dial. Rendered in blue on SBGH289 and black on SBGH291, both dials feature a clean design pairing a large handset with a legible layout. The bold, multi-faceted indexes are affixed onto the dial via a swaging process that ensures their resistance against shocks, and the hands are differentiated in shape to enhance time telling even at a glance. Both dials are also matte, which creates less reflections and makes them easier to read. Ample amounts of LumiBrite is applied to the hands, markers, and bezel for nighttime visibility. There is also a small luminous pip near the date at three in compliance with ISO.

Rated to 200 meters, The case on both models measures 43.8mm in diameter, 14.7mm in thickness, and 51mm in length from one end of the lug to the other. SBGH289 has a case and bracelet made of stainless steel and weighs 206 grams. SBGH291 is High-Intensity Titanium, which provides notable scratch and corrosion resistance, as well as a substantial weight reduction at 142 grams. Every component of these two watches is made to last, with easy maintenance built into the architecture of the case. Therefore, the case, stem pipe, crown, and rotating bezel (which has a four-part design) allow for easy disassembly and re-assembly at Grand Seiko Service Centers.
Caliber 9S85 is a sophisticated Grand Seiko Hi-Beat automatic movement running at 36,000 bph. This modern caliber makes use of innovations to its mainspring, hairspring, escapement, and gear train to improve precision, longevity, and overall reliability. Grand Seiko manufactures this movement from start to finish at Studio Shizukuishi in Iwate Prefecture, the home of Grand Seiko’s mechanical timepieces.

Best Grand Seiko Sport goes diving

In 2021, Grand Seiko Spring Drive watches introduced a high-beat watch inspired by the slender and beautiful white birch trees of the Hiraniwa Plateau in northern Japan. This timepiece was warmly praised by watch fans worldwide for its intricately textured dial and for the revolutionary Caliber 9SA5 that powered it. Its wide acclaim culminated in its selection as the winner of the Men’s Watch prize at the 2021 Grand Prix d’Horlogerie de Genève.

Today, a new creation powered by the latest and finest Grand Seiko Spring Drive watches Caliber 9RA2 captures the atmosphere of a white birch forest but in a subtly new way that echoes the feeling of the forests
of Shinshu, home to the studio where all Grand Seiko Spring Drive watches are made. The watch will be available at the Grand Seiko Boutiques and selected retail stores worldwide in February 2022. The craftsmanship is evident in every detail. The delicately textured dial and the tempered blue seconds hand reveal an artistry that is matched by the ‘frost’ finishing of the movement, whose beauty is clearly visible through the sapphire case back. To watch the completely smooth glide
motion of the seconds hand as it moves serenely across the subtly patterned dial is to be brought closer than ever to the tranquil, seamless and natural flow of time. The delicate texture of the movement’s finish reflects the frost that winter brings to the trees in Shinshu. The bridge lines and hole edges are diamond-cut to reflect light from all angles and the jewels and the tempered blue power reserve indicator add a quiet sparkle that is a delight to behold. Caliber 9RA2 delivers a power reserve of up to 120 hours and is accurate to ±10 seconds per The watch’s design is true to the Grand Seiko Style defined back in 1967 with the celebrated 44GS. However, it also announces an important step forward in Grand Seiko design. To be known as the Grand Seiko Evolution 9 Style, this new grammar of design takes Grand Seiko’s ideals of beauty, legibility and wearing comfort to new levels. Its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate to give the case a quiet and harmonious glow. Its powerful hands and grooved, prominent markers ensure perfect legibility. The case’s center of gravity is lower, and the bracelet has just the right width and depth to ensure that the watch sits easily and securely on the wrist.

Replica Best Grand Seiko Heritage

2002 saw the creation of Grand Seiko’s first GMT watch and, five years later, the first Seiko Spring Drive Chronograph was released. Both these technical developments received immediate acclaim and, ever since, have featured in a range of Grand Seiko creations of very different styles. Today, two Seiko Spring Drive limited edition timepieces are introduced that commemorate the 20th anniversary of the first Grand Seiko GMT watch and the 15th anniversary of the first chronograph watch. Both join the Grand Seiko Sport Collection and their dials take their design inspiration from the wintery snowscapes of the mountains that surrounds the studio where they are made, in Shinshu in central Japan.

The watches are as rugged as the Hotaka mountains that the Grand Seiko watchmakers can see from the Shinshu Watch Studio. The case and bracelet of the GMT version are in stainless steel while the GMT Chronograph version is made from high-intensity titanium. The dials capture the rough texture of the snow that can be seen high in the mountains in late winter and early spring, when strong winds carve unique patterns as they whip across the snow surface. The blue accents on both dials echo the bright blue color of the winter sky in Shinshu.

Both are powered by specially adjusted Spring Drive movements which offer an enhanced accuracy rate of ±10 seconds per month. Both feature a secure see-through case back through which can be seen the 18K gold Grand Seiko lion emblem which graces the oscillating weights as an indication of the enhanced accuracy.
This Seiko Spring Drive Chronograph measures elapsed time up to 12 hours with an accuracy of ±0.5 seconds per day. Thanks to the regulation system that is unique to Spring Drive, its accuracy remains at this high level even when the power reserve is low. Equally importantly, it measures elapsed time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed and not just at the nearest “tick”.
Thanks to Grand Seiko’s unique Spring Drive technology, the seconds hand glides silently and smoothly, with no “tick”, across the dial, perfectly reflecting the natural and continuous flow of time. The power reserve is 72 hours when fully wound and is shown on the discreet indicator next to the eight o’clock marker. The GMT hand allows a second time zone to be shown and a third can also be displayed using the 24-hour bezel. The hour can be adjusted without compromising the accuracy.
The GMT version will be available as a limited edition of 1,500 at the Grand Seiko Boutiques and selected Grand Seiko retailers worldwide in March 2022, while the Chronograph GMT version is a limited edition of 700 and will also be available at the Grand Seiko Boutiques and selected Grand Seiko retailers worldwide in February 2022.

Grand Seiko Evolution 9

For over sixty years, advances in the fundamentals of watchmaking, precision, durability and beauty, have been of paramount importance to Grand Seiko. With the Grand Seiko Spring Drive Caliber 9RA5 and the Hi-Beat 36000 Caliber 9SA5 launched in 2020, Grand Seiko took an important step forward in precision and overall performance. In 2021, a new Spring Drive movement, Caliber 9RA2, was made. Grand Seiko Evolution 9 has the same high functionality as Caliber 9RA5 but, thanks to the repositioning of the power reserve indicator to the back of the movement and the reduction of the height of the hands above the dial, it allows a slimmer case profile.

Today, Grand Seiko introduces two watches featuring Calibers 9SA5 and 9RA2 that are made of Ever-Brilliant Steel*, a type of stainless steel which is more corrosion resistant and therefore more durable than that which is commonly used in watches today. It has a brilliant white hue that enhances the beauty of the watch and is perfectly suited to the Grand Seiko Style, which was established in 1967 and whose 55th anniversary these two creations celebrate.
Both calibers deliver significant advances in performance, thanks to innovations that only a fully integrated manufacture could create. The Hi-Beat 9SA5 movement offers a power reserve of 80 hours while Caliber 9RA2 offers a power reserve of 120 hours with a precision rate of +/- 10 seconds per month. Remarkably, both movements are thinner than their existing counterparts and make possible slimmer cases that are true to the design principles of the Grand Seiko Style that was established with the celebrated 44GS.
Both timepieces share the same dial design which has a depth and a texture that attract the eye and take the imagination upwards towards the sky at night. The deeply etched pattern is that of the elliptical orbit of the stars as they move across the heavens. The Grand Seiko Evolution 9 sharp edges of the hour and minute hands provide a pleasing contrast with the gentle curves of the dial pattern. The gold-tone seconds hand extends right across the dial and its motion captures the serene passage of celestial time. The dial of the Hi-Beat version is blue, while the Spring Drive version is in dark gray.

The see-through sapphire crystal backs reveal the beautifully finished bridges and are clear evidence of the skilled craftsmanship of the men and women of the two studios where the watches are made and hand assembled. The Hi-Beat creation is the work of the Grand Seiko Evolution 9 Studio Shizukuishi while the Shinshu Watch Studio is the home of the Spring Drive version.
Both watches will be available as limited editions of 550 at the Grand Seiko Boutiques and selected Grand Seiko retail stores worldwide in February 2022.

Grand Seiko presents a Spring Drive masterpiece

High up in the mountains of the southern part of Japan’s Shinshu region is Achi, a village that is famous for its spectacular night skies. Thanks to its high elevation, its remoteness and the crisp cleanliness of its air, the stars above Achi seem almost within touching distance and the immensity of the universe is brought into the sharpest focus. With its platinum case and with the glide motion seconds hand that moves silently and continuously across the deep blue, starspeckled dial, this new Grand Seiko masterpiece brings to life both the majesty of the heavens and the ever-changing and yet eternal nature of time itself.

When the Spring Drive manual-winding caliber 9R02 was first presented in 2019 to mark the 20th anniversary of Spring Drive, it won favor among watch enthusiasts worldwide for its delicate yet understated refinement. With its hand-crafted quality and with the glide motion seconds hand that is the signature of Spring Drive, it exemplified Grand Seiko’s uniquely Japanese sensibility.

Today, in celebration of the 140th anniversary of the foundation of the company, Grand Seiko presents a new Spring Drive masterpiece powered by this caliber and made by the elite team of watchmakers at the Micro Artist Studio in Grand Seiko’s manufacturing facility in Shiojiri, located in the same Shinshu region as Achi. The watch will be available as a limited edition of 50 at the Grand Seiko Boutiques in August 2021.
The blue of the dial has a remarkable depth that is accentuated by the quiet and delicate sparkle of what appear to be distant stars. A unique manufacturing and finishing technique combining stamping, plating and painting gives the dial a different aspect at each and every viewing angle, just as does the sky above Achi. The Platinum 950 case is carefully engraved with a pattern which is replicated in different directions on the Zaratsu polished case, again capturing the exquisite order and ever changing aspect of Achi’s starry skies.
The watch presents a refined and slim profile with a diameter of 38.5mm and depth of 9.8mm.The hour and minute hands and hour markers are made of 14k white gold to ensure that their brilliance endures for decades. The Grand Seiko name, the minute markers and all the other markings are etched into the dial.
Every aspect of the movement is designed without compromise. The power reserve indicator is on the back side of the movement next to the barrel whose shape echoes that of the bellflower that is the symbol of Shiojiri. The rims of the bridges, the holes for the rubies and the screws are all expertly hand polished to a perfect mirror finish and the tempered blue screws stand out in contrast to the hairline finish of the bridges to heighten the perception of the perfection of the engineering. The caliber also incorporates an 18k yellow gold plaque on the lower bridge, which carries the engraved words “Micro Artist” but which can, if the owner so wishes, be replaced with a word of his or her choice.
The movement is assembled and adjusted by the craftsmen and women in the studio including Katsumi Nakata, who has been recognized as a Contemporary Master Craftsman and is now the third member of the Micro Artist Studio team to have received the Medal with Yellow Ribbon from the Japanese government.
The outstanding 84 hour power reserve of Caliber 9R02 is realized thanks to the Dual Spring Barrel, in which two mainsprings are set in parallel within a single barrel, and the Torque Return System. When the mainspring has been fully wound and the torque output is at its highest, approximately 30% of the available power is not needed to maintain the precision of the watch and is in effect wasted in a normal movement. The Torque Return System uses this energy to rewind the mainspring, resulting in an increase in the power reserve. In Caliber 9R02, this system is activated for 48 hours after the mainspring has been fully wound.
The Micro Artist Studio is a luxury watch studio that makes the Grand Seiko Masterpiece Collection, a series of unique watches that combine the best in horological technology with hand craftsmanship of the highest order. The studio was established in 2000 with the purpose of “uncovering, examining, and mastering the technologies and skills passed on by our predecessors for the production of luxury watches”. The team consists of craftsmen and women, each an expert in their respective fields, such as movement design, assembly and movement finishing.

A Grand Seiko quartz GMT watch celebrates the 140th anniversary of the company’s foundation.

Kintaro Hattori founded his company in 1881 and led it until his death in 1934. His philosophy was that his company should be “Always one step ahead of the rest” and nothing better proves the power of his vision than Best Grand Seiko Sport with its uncompromising standards and relentless determination to push back the frontiers of fine watchmaking.

Today sees the release of a new 9F86 quartz GMT creation that adds a new dimension to the Best Grand Seiko Sport replica collection. The case is simple in design but, with its muscular shape and sharp, Zaratsu polished surfaces, it presents a powerful sports aspect. The dial has gold color details and it is offered as a limited edition of 2,021 to mark the 140th anniversary of Seiko’s foundation. Two other versions with red and blue accents join the main Grand Seiko collection.
A design perfect for both sport and daily use.
All three new creations are all quintessentially Grand Seiko in every way, combining the highest level of precision and durability with supreme legibility and the quiet yet instantly recognizable brilliance that is the Grand Seiko hallmark. The case ridges are sharp and crisp. The bezels are ceramic and so are almost impervious to scratches. Every detail is fashioned to enhance the legibility of the time and the precision that Caliber 9F86 delivers. The two-tone dial ring allows the night and day hours indicated by the GMT hand of matching color to be read instantly. Legibility at night is ensured by the use of two colors of LumiBrite: green for the hour hand, minute hand and indexes, and blue for the GMT hand. The ceramic bezel allows the time to be read instantly and accurately in the GMT 24 hour format.

The hour hand is independently adjustable so that the precision is maintained even
when adjusting the time to a second time zone. A date with an instant change mechanism, a sapphire crystal, 20 bar water resistance and magnetic resistance of 16,000 A/m complete the specifications. Even with this high functionality, the case diameter is a modest 40mm, making the watch perfect for sport and daily use.

The blue creation features a deep blue dial and bezel to match the bright blue color accents of the dial. All three watches will be available in June 2021 at the Grand Seiko Boutiques and selected Grand Seiko retail stores worldwide. SBGN023
About Caliber 9F
When Caliber 9F was created in 1993, the goal was straightforward but ambitious. As the quartz caliber for Grand Seiko, it should set new durability and precision standards and allow all the aesthetics of Grand Seiko to be fully expressed. A backlash auto-adjust mechanism eliminates any shudder in the seconds hand. The date changes in the blink of an eye. A twin-pulse control system allows the minute and seconds hands to extend right to the edge of the dial. The use of aged and selected quartz crystals and thermo-compensation ensure high precision of ‒10 to +10 seconds per year. Thanks to these unique characteristics, Caliber 9F can lay a strong claim to be the world’s highest performance quartz watch. Caliber 9F86 was created in 2018 and offers a GMT function in addition to the base characteristics of Caliber 9F. Full details of Caliber 9F86 and the story of its

A new Spring Drive Chronograph with gold highlights joins
the grand seiko replica Sport Collection
Kintaro Hattori founded his company in 1881 and led it until his death at the age of 73 in 1934. His business philosophy was that his company should be “Always one step ahead of the rest” and, while it was not created until 1960, nothing better expresses the power of his vision than Grand Seiko with its unique design, leading edge manufacturing and exquisite finishing. In honor of the 140th anniversary of the foundation of the company, replica grand seiko proudly announces a new Spring Drive chronograph that perfectly embodies Kintaro Hattori’s vision.
This powerful watch allies all the high functionality of the Spring Drive chronograph Caliber 9R86 with a new design and a new combination of materials. The result is a timepiece of rare refinement.
The bezel catches the eye immediately with its dodecahedron shape, its zirconia ceramic outer layer and 18k gold base. Thanks to this combination of materials, it is both strikingly beautiful and highly durable.
The case, too, uses contrast to deliver a visually arresting impression. Its top surfaces have been given a hairline finish while the sides showcase the distortion-free perfection that only Zaratsu polishing can deliver. The dial is as rich as it is legible. The gold color hands and hour markers stand out against the pure black dial and, as the markers are aligned exactly to each apex of the twelve-edged bezel, both time of day and elapsed time can be read precisely and at a glance.
The 18k yellow gold buttons that operate the chronograph are prominent and designed to ensure secure operation but they are also streamlined so as to look just as good when under a shirt cuff as on the sports field.

Seiko 140th Anniversary Limited Edition Re-creation of King Seiko KSK

2021 marks the 140th anniversary of Seiko’s foundation and a re-creation of the second series of King Seiko, known as the King Seiko KSK, will be released in celebration of this landmark.
From the first Grand Seiko in 1960 to the automatic chronograph in 1969, the sixties was a decade of important advances in both technical and design development that laid the foundation for the company’s future success in the prestige watch arena. Alongside Grand Seiko, one other series in particular demonstrated the company’s ability to create mechanical watches with high accuracy. It was called King Seiko and, in addition to its precision, it offered a powerful yet graceful design that symbolized the high quality of its construction.
In contrast to the gentle rounded contours of the first King Seiko creation, the KSK case was strikingly sharp and angular and had a contemporary feel. Its flat surfaces and multi-faceted corners caught the light from any angle and gave the watch a new and striking brilliance. The case’s durability is also enhanced by the super-hard coating which protects the watch from scratches.
The sharp, bold faceted lugs feature large flat planes and razor sharp angles and are Zaratsu polished to a distortion-free mirror finish.
The new re-creation brings the 1965 KSK back to life in every detail. The combination of the flat dial with the faceted indexes and broad, sharp hands re-creates the refined elegance of the original.
The faceted and textured twelve o’clock index ensures high legibility.
The case back bears the same emblem as the original. And as a proof of the limited edition, “Limited Edition” and the serial number are printed.
Even with an automatic movement and the addition of a date window, the new watch retains its slim profile and is just 0.5mm thicker than the original, thanks to the thinness of Caliber 6L35. The eight beat per second movement has 26 jewels and offers a power reserve of 45 hours.

SEIKO PROSPEX Seiko 140th Anniversary Limited Editions

When Kintaro Hattori founded his company in 1881, he was just 21 years old. During his fifty years at the helm, Replica Seiko became the leading watch company in Japan, with its own design and production facilities. This achievement was a direct result of his single-minded vision that Seiko should be “Always one step ahead of the rest”. His words resonate still and continue to inspire Seiko today. Throughout this year, Best Grand Seiko will release a series of creations that embody the spirit of Kintaro’s words and honor the140th anniversary of the founding of his company. The celebrations start with a series of Prospex, Presage and Astron watches inspired by the landscapes, seascapes of Japan.

From Seiko Prospex, a new series focuses on the beauty of nature. The watches capture the deep green scenery of the rich ocean that surrounds Iriomote Island.

The island of Iriomote in Okinawa Prefecture attracts divers from all areas of the world. Its abundant coral reefs teem with marine life but the island’s special charm lies in the primeval and pristine mangrove forests that surround it. Further, Iriomote is home to several species of flora and fauna that are rare and, in some instances, unique to the island.
As a culmination of Seiko’s developments in watchmaking technology, today, a diver’s watch in a stainless steel case with a green dial offering water-resistance of up to 300m is introduced.
The watch has sapphire crystal with anti-reflective coating on the inner surface. The bezel display material is zirconia ceramics to ensure both high legibility and rigidity.
The gold-colored second hand, reminiscent of the sunrise over a lush virgin forest, makes a strong presence on the dark green dial.
The watch is powered by the 8L35 movement which was developed expressly for diver’s watches and is assembled by hand at the Shizukuishi Watch Studio. The watch is offered with an additional dark green silicone strap.

Based on the 1968 Diver’s 300-meter water resistant watch, this model has been given a modern design interpretation. While retaining the sharp and powerful design of the original, the new model features a slimmer bezel and a contemporary design for its minute and hour hands. The watch is offered with an additional dark green silicone strap.
The watch incorporates a case design that has long been nicknamed “SUMO” by fans because of its dependable and dignified structure.
The watch is water-resistant to 200 meters and has a screw-down crown to ensure the safety of the divers from any accidental operations.
