The New Grand Seiko Spring Drive 8 Days Jewelry Watch Costs $185,000

To celebrate the 140th anniversary of the company’s establishment, Grand Seiko has just announced the new masterpiece Spring Drive 8 Days Jewelry Watch SBGD207, which will be limited to only 15 total editions. The mew model is set at $185,000 and will be available in the Grand Seiko Boutiques in May 2021.

Like the 2020 version, set with diamonds and blue sapphires, the 2021 Jewelry Watch draws its inspiration from nature. For this verdant timepiece, Grand Seiko channels the green shades of trees reflected on Mishaka Pond, a body of water close to Lake Suwa near Shiojiri, Japan, and close to Grand Seiko’s Micro Artist Studio, where much of its haute horologerie timepieces are developed.

The new Jewelry Watch has a 43-mm 950 platinum 950 case, 13.5 mm thick, the surface of which is finished with a special form of Grand Seiko’s “Zaratsu” polishing which the brand says has been specially adapted for platinum.

Like last year’s Jewelry Watch, this year’s also uses thick lugs, a wide bezel, and a prominent, diamond-tipped crown, all of which add a luxurious weightiness to the watch. The case is secured to the wrist via a green crocodile leather strap, itself secured via a three-fold clasp with push button release.

Glittering underneath the anti-reflective-coated, box shaped sapphire crystal is the namesake gem-bedecked dial, which instantly grabs attention with both by its vivid colors and layered construction.

Two outer sectors of diamonds and green garnets are all set within an 18k gold base, and surround an inner sector of green mother-of-pearl; in total, the watch hosts 97 total diamonds and 24 green garnets.

Powering this Masterpiece Collection watch is a Spring Drive movement, the Grand Seiko Caliber 9R01. This manually-wound, quartz-regulated caliber is accurate to +/-0.5 seconds per day (or +/-10 seconds per month), hosts an 8-day power reserve, and has an independent hour-hand adjustment mechanism for quickly changing time zones.

The movement is visible, with its expert finishing, via an exhibition caseback, its bridge evoking the silhouette of Mt Fuji and the landscape that surrounds the Micro Artist Studio. A power reserve indicator is also visible on the movement, with its scale engraved in blue up to 8.
