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.
Now, two decades on, Grand Seiko introduces a new generation Spring Drive caliber that is slimmer, even more precise and has a greater power reserve. Caliber 9RA5 takes Spring Drive technology to a new level of excellence and opens a new era in the history of Grand Seiko.
This new design has all the hallmarks of 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 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.
To demonstrate its power, strength and precision, the first creation to be powered by Caliber 9RA5 is a professional diver's watch. It has helium and water resistance that meet the challenge of saturation diving at depths of up to 600 meters.
The dial color is Grand Seiko blue, a special color that symbolizes the brand. It is a special specification unique to limited edition.
The watch is presented in a special Grand Seiko 60th anniversary box with an interchangeable blue silicone strap. It will be available worldwide in August as a limited edition of 700.
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.
The new studio was completed on the milestone sixtieth anniversary of the birth of the Grand Seiko brand. The design is the brainchild of Kengo Kuma, a celebrated Japanese architect also famed for his work on the new Japan National Stadium finished in 2019.
The case in the platinum version is in Platinum 950 and the dial carries the star mark that signifies that its hour markers are in 18k gold. The engraving of the Grand Seiko name on the dial is particularly sharp thanks to the fact that the dial, too, is in 18k gold.
The case in 18k yellow gold version, the dial carries the star mark that signifies that its hour markers are in 18k gold.
The third case is in Brilliant Hard Titanium, which is exclusive to Grand Seiko. It is as light as pure titanium but twice as hard as stainless steel and therefore highly resistant to scratches. Its color is brighter than the other forms of titanium used for Grand Seiko and allows the Zaratsu polished surfaces to stand out even more prominently.
Every aspect of the watchmaking of this creation is handled with meticulous care but the engraving, especially, is a true labor of love. Master engraver Kiyoshi Terui and his small team engrave all the elements on the dial by hand. Their work covers not only the hands and indexes but also the Grand Seiko name and the star mark at the 6 o’clock position. Every stroke of the blade has to be exactly right, a task that is all the more delicate with this watch as both the plates on which the indexes and the minute track are engraved are curved. These plates and the dial itself are made of 18k white gold. The engraving of each watch requires many days of this intense and highly skilled work. The engraving may be intricate but it is also powerful. Its straight lines accentuate the legibility of the time, making this watch true to the Grand Seiko aesthetic, while the whole watch has the soft, gently angular profile that is part of the Elegance Collection’s signature.
"Deep Purple (Kokimurasaki)" is used for the dial color, a refined color with depth.
The dial color uses the "light white" color, a traditional Japanese color.
The brilliance of the diamond is further enhanced to create the arms in a bright manner.
