Grand Seiko SBGZ007
Model SBGZ007 is a luxury wristwatch by the Grand Seiko brand in the “Grand Seiko Masterpiece Collection” series.
The watch was offered as part of the “Seiko 140th Anniversary Limited Edition” in August 2021. The platinum 950 case is carefully engraved with a pattern repeated in different directions on the polished Zaratsu case, which in turn captures the ever-changing aspect of the spectacular starry sky above Achi. Achi, just like the Micro Artist watch studio of Grand Seiko, is located in the Shinshu region of Japan.
The SBGZ007 is powered by a Spring Drive Cal. 9R02, which achieves the remarkable accuracy of ±1 second per day (±15 seconds per month) and a very high power reserve of eight days (84 hours).
