Grand Seiko Heritage Collection Watches

Grand Seiko. As one of the very few fully integrated watch manufactures in the world, Grand Seiko possesses a mastery over the full breadth of the watchmaking process from the research and development of component materials to manufacture, assembly, adjustment, inspection and shipment. Grand Seiko becomes an independent brand and no longer co-branded with Seiko.

Grand Seiko’s 10 beat movement delivers an accuracy of +5 to –3 seconds a day, a power reserve of 55 hours and the durability for which every Grand Seiko watch is renowned. This is the result of many years of development and of advances both in the design and manufacture of Replica GS watch.

Grand Seiko defines the essence of watchmaking in the elements of precision, beauty, legibility, durability and ease-of-use. As a world-leading watch manufacture, Grand Seiko embodies that very essence in the unrivaled quality in every Grand Seiko watch presented to the world. Manfredi Jewels is an Authorized Grand Seiko Dealer.

With the Grand Seiko Heritage Collection SBGH269 Limited Edition watch, the increasingly global brand from Japan continues its trend of producing stunningly beautiful dials that are simply unobtainable in its core collection. With Reference SBGH269, Grand Seiko brings to market a warm-hued dial celebrating the colors of fall in its home country.

CHARACTERISTICS OF GRAND SEIKO WATCHES Committed to reaching new levels of timepiece craftsmanship, the Japanese watchmakers at Grand Seiko have worked tirelessly to obtain international prestige and acclaim. Since its founding in 1960, Grand Seiko have been creating men’s and women’s watches of long-lasting durability, well-built components, and an uncompromised beauty in design.

Grand Seiko Replica Grand Seiko watches have a distinctive look that reflects Japanese artistic tastes. The design is notable for the purity, simplicity and subtlety of its lines. Grand Seiko calls it functional beauty, a style that does not interfere with the reading of the time, but enhances it with harmonious case lines and uncluttered, easy-to-read dials.

Grand Seiko For fifty years, the story of Grand Seiko has been the story of a team’s dedication to perfecting the deceptively simple idea of creating the ideal watch. Though times change, the spirit and essence of Grand Seiko has remained the same.

Grand Seiko takes great pride in their quartz movements for mainly two reasons: their quartz movements are easily among the best ever made, and owing to their Seiko heritage, they are the father of quartz movements generally. Indeed, the same division that made the first production quartz watch makes Grand Seiko quartzes today, 46 years later.

In 1998, the creation of the 9S mechanical caliber opened a new chapter in the Grand Seiko story.
Today, the pages turn again with the launch of a new high beat mechanical caliber, 9SA5, 
which, in its design and functionality represents an advance just as important as the first 9S.
9SA5 is more than just a new caliber. It is an entirely new movement and the foundation upon
which a whole new generation of Grand Seiko mechanical watches will be created.
Deploying all the skills and experience we have gained over the past 60 years, 
beyond doubt, the finest mechanical caliber that we have ever created.
9SA5 is, A watch offered in a limited edition of 100 will be the first to be powered by this new caliber.
It will be available at the Grand Seiko Boutiques in August 2020.

36,000 vph, 80 hours of power reserve and a slim profile.
The challenge for any watchmaker who creates a high beat movement is to strike the perfect balance between precision, 
power and size without compromising on any of these parameters. In developing the 9SA5 caliber, 
the Grand Seiko development team set out to deliver the same level of stable accuracy as that of their existing 36,000 vph movement
but to deliver a longer power reserve and so makes the watch even more practical in everyday life.
They succeeded in characteristically uncompromising style.
Caliber 9SA5 has a precision rate of +5 to –3 seconds a day and a power reserve of 80 hours.

Dual Impulse Escapement

The escapement is entirely new and was developed in-house. It enables the escapement wheel to transmit power directly to the balance, leading to an efficiency increase. It is unique in that, in one direction, power is transmitted directly to the balance while in the other it is via the pallet fork, as in a traditional escapement. Both pallet fork and escapement wheel are made using MEMS technology.

Free-sprung Balance

9SA5 uses a new and special free-sprung balance developed for this caliber. It retains its precision for longer and is more resistant to shock and friction. While the current Caliber 9S uses a flat hairspring, 9SA5 uses an overcoil, whose curve shape was decided after more than 80,000 simulations with the result that its performance is optimized in every possible position. The uniqueness is that it can improve the isochronism. The secret lies in the precision manufacture of the components as well as the extraordinary adjustment skills of the watchmakers at the Grand Seiko Studio Shizukuishi.

Horizontal Gear Train

The new caliber is 15% slimmer than the current Best Grand Seiko high beat caliber, thanks to the innovative horizontal layout of the barrel and gear trains. In addition to these three new components, Caliber 9SA5 has other features that contribute to its extraordinary performance. Two barrels, arranged in sequence, enhance the power reserve, the date change is virtually instantaneous and the positioning of the winding stem close to the rotor allows the watch to sit closer to the wrist.

The movement is as beautifully finished as it is efficient. The bridge has a gently curving outline that is inspired by the shapes of Mt. Iwate and a bend in the Shizukuishi River that runs near the studio where the watch is made.

Just as Caliber 9SA5 makes a significant and defining statement about the next stage of Grand Seiko’s technical development, 
the design also has a distinctive look that marks a new beginning.
The watch is, of course, true to the Grand Seiko Style that was defined back in 1967 with the celebrated 44GS
but it is subtly different in ways that are much more than cosmetic.

This new design has all the hallmarks of Fake Grand Seiko but also offers enhanced comfort and legibility. The slimness of the caliber does much to ensure that the watch can sit easily but it is combined with slightly wider lugs so that the watch also stays more solidly on the wrist.

The already legendary legibility of Replica Grand Seiko is further enhanced by the increased volume of the hour hand and by the hour markers that are more prominent, just as they were in the first Grand Seiko of 1960. The Grand Seiko logo, indexes and calendar frame are in 18k yellow gold.
