Grand Seiko Spring Drive watches are handcrafted by the skilled artisans of the Shinshu Watch Studio. The workshop, located in the city of Shiojiri, looks out upon the Hotaka Mountains, which were born long ago from volcanic activity that reshaped the continent and pushed the peaks up from beneath. Powerful winds and snow sculpted the faces of the cliffs over many long years to create a dynamic mountain range that is honored by this powerful sport watch. The Sport Collection Spring Drive GMT Triple Time Zone SBGE295 has a patterned dial that represents these sheer cliffs and features a green color designed to capture the brilliance of Hotaka’s short summers. The watch features the Caliber 9R66 Spring Drive movement with GMT function. Its rotating bezel with a 24-hour scale is crafted from sapphire glass and is complemented by another 24-hour dial ring display. Together, they allow the wearer to read the time in three time zones.<br /><br /><strong>Exterior:</strong><li>Case Material: Stainless steel</li><li>Caseback: Screw case back</li><li>Glass Material: Dual-curved sapphire crystal</li><li>Glass Coating: Anti-reflective coating on inner surface</li><li>LumiBrite: LumiBrite on hands, index(es) and bezel</li><li>Case size: Diameter 44mm Lug-to-lug 50.8mm Thickness 14.7mm</li><li>Band width: 21mm</li><li>Perimeter of band: 194mm</li><li>Clasp type: Three-fold clasp with push button release</li><br /><strong>Movement:</strong><li>Caliber No: 9R66</li><li>Movement Type: Spring Drive</li><li>Power reserve: Approx. 72 hours(3 days)</li><li>Accuracy: ±15 seconds per month (±1 second per day)</li><br /><strong>Features:</strong><li>Water resistance: 20 bar</li><li>Magnetic resistance: 4,800 A/m</li><li>Rotating bezel (24-hour display)</li><li>Screw-down crown</li><li>30 jewels</li><li>24-hour hand (dual time display function)</li><li>Power reserve indicator</li><li>Calendar-linked time difference adjustment function</li>Grand Seiko Style #: SBGE295
