Grand Seiko proudly celebrates the life and achievements of Kintaro Hattori with SBG005, a Spring Drive masterpiece 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, resulting in an interplay of light and shadow on the dial that is an essential part of the signature of every Grand Seiko watch. As has been the tradition since the 1960s, a star mark on the dial denotes that the indexes are made of solid gold. Additionally, 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.
SBGZ005 is powered by Caliber 9R02, a Spring Drive caliber 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 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." If the owner so wishes, this can be engraved with a word of their choice.
SBGZ005 is a limited edition of 50 and available in Grand Seiko Boutiques worldwide.
