In 2020, Grand Seiko released its first jewelry masterpiece, a platinum cased Spring Drive watch whose design took inspiration from the winter mornings in the Shinshu region which is home to the Micro Artist Studio where the watch was created. Now Grand Seiko has chosen another unique aspect of the studio’s stunning and varied natural surroundings as the motif of another jewelry watch to celebrate the 140th anniversary of the company’s establishment.
This new jewellery masterpiece takes inspiration from the infinite shades of green on the pristine, crystal clear water of Mishaka Pond, which is near to Shiojiri where the Micro Artist Studio is located. Japanese painter Kaji Higashiyama’s famous 1982 work “Vibrant Green” perfectly depicts the pond’s green beauty. Inspired by the Mishaka Pond’s enchanting beauty and serenity, this new Spring Drive timepiece boasts a green mother-of-pearl dial and the green garnet indexes.
The carefully selected green garnets and tapered baguette diamonds that accompany them act as minute and hour markers. They are set into an 18k white gold base and are separated by 48 additional diamonds and 12 garnets that are individually set around the markers to further enhance the depth and beauty of the dial. The gems are placed exactly horizontally so that they catch the light evenly. The garnet at twelve o’clock is slightly wider than the rest to ensure the perfect legibility of the time.
The Spring Drive 8 day Caliber 9R01 delivers an accuracy rate of ±10 seconds a month. It offers a power reserve of 192 hours when fully wound. Caliber 9R01 incorporates three barrels arranged in sequence to deliver the extended power reserve which is shown by an indicator visible through the sapphire case back along with the exquisite finishing of the one-piece bridge, designed in the image of Mt. Fuji, and the rubies, which evoke the lights of Suwa City below Shiojiri.
The case is made of Platinum 950 and is finished with a form of Zaratsu polishing that is specially adapted for platinum and makes possible the distortion-free surfaces and sharp ridges that are an intrinsic part of the Grand Seiko aesthetic.
This Grand Seiko masterpiece is offered in a limited edition of 15 and will be available in the Grand Seiko Boutiques in May 2021.
