キャリバー9S 20周年記念 新デザインコレクション

Caliber 9S 20th Anniversary Limited Editions

Three special movements, a new case and a unique dial

To celebrate the twentieth anniversary of 9S caliber, the Grand Seiko team has created a series of three limited edition timepieces, each of which pays homage, in its own way, to the remarkable heritage of the 9S caliber.

To mark this 20th anniversary, Grand Seiko’s award-winning designer, Nobuhiro Kosugi, has crafted a new design based on the foundation of his original 1998 Caliber 9S model.

Built around an elegant yet simple watch face, these new designs exemplify a uniquely Japanese style.

Two finely polished lines extend to the very edge of the lug, where these curved surfaces meet the hairline finish. This creates a perfect triangle that can only be achieved by the most skilled Grand Seiko craftsmen and women through the careful use of multi-faceted Zaratsu polishing.

Grand Seiko 9S Mechanical

With the exception of the arrival of the very first Grand Seiko watch in 1960, perhaps the most important moment in the history of Grand Seiko was the creation of the 9S mechanical caliber in 1998.
The 9S caliber was entirely new and designed from scratch to deliver the high precision and excellent durability for which Grand Seiko was renowned.

The 9S caliber has continued to evolve over the years. This evolution includes the use of new SPRON alloys for the main and balance springs, and the application of MEMS engineering, a technique that allows key components to be manufactured to tolerances as small as one thousandth of a millimeter. Today, 9S is the platform upon which the entire Grand Seiko suite of mechanical calibers is built. Thanks to its high precision, long power reserve and robust construction, 9S has earned a deserved reputation as one of the world’s finest automatic movements.

HISTORY OF V.F.A.
V.F.A.を生み出した輝かしい歴史

The term “Very Fine Adjusted” may not inspire the uninitiated, but “V.F.A.” is a designation revered by the Grand Seiko team. First used in 1969, it described a Grand Seiko watch adjusted so skillfully that it achieved a degree of precision far beyond the Grand Seiko Standard.

New dial pattern

The dial is exceptional. Its design incorporates the special insignia used back in the 1960’s to designate watches made by Daini Seikosha, the company known today as Seiko Instruments Inc. This long-cherished insignia alternates with the initials “GS” in a delicate mosaic that radiates out from the center of the dial in a geometric pattern.

MOVEMENT

Caliber 9S85 Special

The gold version’s 10-beat movement Caliber 9S85 operates at the higher-precision “Special” standard of accuracy. First established in 1998, the GS Standard is even more precise than the most widely recognized global standard. However, the Grand Seiko Special Standard is higher still. Because it takes an extremely skilled watchmaker many years to reach this standard of accuracy, the number of watches that can be produced each year is limited.

This version is adjusted to the Grand Seiko Special standard and delivers a precision rate of +4 to -2 seconds per day.

“SPECIAL” is inscribed on the dial in testament to this higher standard of accuracy.

MOVEMENT

Hi-Beat 36000 Caliber 9S85

The challenge of making a high-beat movement is one that only a few watchmakers choose to accept. With its higher oscillation rate of ten beats per second, greater accuracy is achievable, but this increased precision comes at a price because the faster rotational speed can take its toll on the power reserve and even the longevity of the whole movement. Grand Seiko's 10 beat movement meets these challenges and 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.

The watch is equipped with a special oscillating weight made of titanium and tungsten.
The blue titanium surface, achieved by means of anodic oxidation*, is accented in yellow with a GS Lion Emblem and is engraved the words “Caliber 9S 20th Anniversary Since 1998”.

*Anodic oxidation treatment
This is a surface treatment in which metals are subjected to electrolysis so as to generate artificially an oxide film. Titanium oxide film produces color according to the light refraction index, enabling production of different colors by varying the thickness of the oxide film.
