Grand Seiko Watch Spring Drive 8 Day Power Reserve. SBGD001.
The Grand Seiko Spring Drive 8 Day Power Reserve watch is a completely new and innovative concept from Grand Seiko watches. The first thing that you will notice is the diamond dust dial housed beneath the sapphire crystal glass which is inspired by the glistening snow that is found in the Nagano region where the watch is born. The unusual shimmering effect is stunning but subtle enough that it doesn’t distract you from the rest of the watch. The dial also boasts five faceted hour and minute hands that are longer than on any other previous Grand Seiko watches while the applied indexes have been treated to a careful polishing. The automatic Spring Drive movement is embraced within a platinum 950 case which has been polished to Grand Seiko’s mirror finish using the well known Zaratsu technique that was derived from the methods used to polish katana blades. This technique gives the watch a glistening and distortion free finish.
When you turn the watch over, the spectacle continues. On the case back, the power reserve sits proudly showing off its 192 hour reserve thanks to the calibre 9R01 movement. The prolonged power is made possible by the use of three barrels that unwind more slowly than a single barrel, consequently extending the power. The back also reveals a one piece bridge which ensures the accurate positioning of each wheel in the gear train, augmenting the efficiency of the transmission of power from the barrels. The bridge is neatly bevelled at the top to outline Mount Fuji while the unmissable rubies and blue screws represent the lights of Suwa, the city just below the Micro Artist Studio where the watch is created. The Grand Seiko Spring Drive 8 Day Power Reserve watch is completed by a black alligator strap for effortless wear and comfort.
