Grand Seiko presents a new manual-winding Spring Drive watch with a fully engraved platinum case and a beautiful white birch dial. Limited to 50 pieces, this new timepiece (reference SBGZ009) from the Grand Seiko masterpiece collection is a bona fide product from the Micro Artist Studio.
Based in Shiojiri in the Shinshu region of Japan, the Micro Artist Studio makes exclusive Spring Drive watches for Grand Seiko. The highly skilled craftsmen and women of this luxury watch atelier handcraft timepieces embodying the beauty of the local surroundings and seasons.
Grand Seiko SBGZ009 is the latest product from this prestigious high horology workshop. It boasts a stunning dial with textures inspired by the expansive forest of white birch trees found at the foot of the North Yatsugatake Mountains in the eastern part of Shinshu.
The silver color dial with its texture evokes white birch forest as it appears during the height of winter, covered by freshly fallen snow.
Made of 14k white gold, the hour and minute hands, as well as each of the hand-applied diamond-cut markers boast a sharp and gleaming finish. The minute track, the lettering and the mark at six o’clock are all carved into the dial. The tempered seconds hand has a harmonious grey dial.
The star mark at six o’clock denotes solid gold hour markers, a Grand Seiko tradition since the 1960s. The minute and seconds hands are shaped by hand to curve gently towards the minute track, ensuring high legibility.
Engraved Platinum Case
The 38.5mm diameter case in Platinum 950 perfectly harmonizes with the much admired Shinshu white birch pattern dial. Fully engraved, it spotlights a distortion-free mirror surface achieved through the Zaratsu polishing technique.
The long individual grooves of the case are painstakingly hand-engraved by the skilled engravers of the Shinshu Watch Studio, which is in the same facility as the Micro Artist Studio. Each groove brings to life the array of white birch trees in a pattern that seamlessly echoes a similar pattern found on the dial.
Grand Seiko Spring Drive Caliber 9R02
The Grand Seiko SBGZ009 White Birch watch houses the manual winding Spring Drive Caliber 9R02. Introduced in 2019, this movement comes with Dual Spring Barrel and Torque Return System. It also offers an outstanding 84-hour power reserve.
Visible through the sapphire crystal case-back, Caliber 9R02 demonstrates the exquisite craftsmanship that is the hallmark of the Micro Artist Studio.
Its barrel has a decoration echoing the bellflower, the symbol of Shiojiri. The two hand-finished bridges with high-polished edges contrast the fine hairline finishing of their other visible surfaces. An 18k gold plaque set on the lower bridge is engraved with the words “Micro Artist,” but if the owner wishes, this plaque can be customized.
Grand Seiko SBGZ009 is only the third fully engraved masterpiece powered by a manual-winding Spring Drive movement. It will be available as a limited edition of 50 pieces at the Grand Seiko Boutiques in June 2023.
