As the year of the 160th anniversary of his birth draws to a close, Grand Seiko proudly celebrates the life and achievements of Kintaro Hattori with a Spring Drive masterpiece. This watch exemplifies Kintaro's dedication to the mastery of every aspect of the watchmaker's art.
The 160th anniversary of Kintaro Hattori's birth is marked with a remarkable timepiece made by the elite team of watchmakers at the Micro Artist Studio. The softly rounded case is made of Platinum 950 and is Zaratsu polished to a perfect distortion-free finish. The sapphire crystal glass is dual-curved and each surface is shaped to ensure perfect legibility.
The dial's intricate pattern is made possible by processing techniques that create a delicate dial surface with varying depths. As has been the tradition since the 1960's, a star mark located at six o'clock denotes that the indexes are of solid gold. The interplay of light and shadow on the dial that is an essential part of the signature of every Grand Seiko watch is accentuated by the application of seconds markers that enhance the legibility of the time. The indexes and the hour and minute hands are in 14K white gold and are specially cut to create a sharpness that amplifies the enduring beauty of the gold.
The watch is powered by Caliber 9R02 which is assembled, adjusted and finished by hand by the craftsmen and women of the Micro Artist Studio. It delivers a power reserve of 84 hours thanks to the Dual Spring Barrel in which two independent thin, long mainsprings are set in parallel in a single barrel, and the Torque Return System. The caliber also incorporates an 18k yellow gold plaque which carries the engraved words "Micro Artist" but which can, if the owner so wishes, be replaced with a word of their choice. This slim and exquisite timepiece has a depth of just 9.6mm and will be available in January 2021 as a limited edition of 50 in the Grand Seiko Boutiques worldwide.
