Introducing: The Grand Seiko Spring Drive 8 Day Power Reserve

I think each hardcore watch geek dreams of claiming a piece hand-crafted by Seiko’s Micro Artist Studio in Shiojiri, located in Japan’s central Nagano locale. The Micro Artist Studio is a little subset of the Seiko manufacture that is the absolute world class unit, answerable for hand-crafting the mind blowing Eichi II , as well as the Credor Minute Repeater and Sonnerie. Today, interestingly, we saw a Grand Seiko that was given the Micro Artist treatment, and it didn’t disappoint.

First, one should understand that the craftsman in the Micro Artist Studio are top, top level. They are the gathering that visits nobody shy of Mr. Philippe Dufour with some regularity, and the gathering that Mr. Dufour right up ’til today holds in amazingly high regard. This is genuine very good quality completing of the greatest request, an as of not long ago, this has been saved for Credor item. I’d always asked why we never saw an insanely very good quality Grand Seiko, and now we have.

Everything about this piece is special, starting with the diamond-dust-covered dial, meant to make the wearer think about a the new snow found in the Nagano area where the watch is conceived. The hands are five sided, and more than traditional Grand Seiko hands. The case is in platinum – 43 mm in diameter (larger, however you’ll see why in a second) – and is reflect cleaned utilizing the famed Zaratsu method characterized by Seiko.

It does so via three separate barrels that breeze and lapse linearly. A solitary expertly completed extension guarantees accurate situating of each wheel in the gear train with the goal that the transmission of force is generally productive. The unbending nature of the single plates also encourages against stuns to the watch. The plate is sloped at top to in fact layout Mt. Fuji, and the insanely high cleaned rubies and blued screws are meant to address the lights of Suwa, the city just underneath the Micro Artist Studio.
