Grand Seiko Evolution 9 Collection SBGE283 SBGC251 SLGA015 (Spring Drive GMT)

--- The Evolution 9 Style In 2020, Grand Seiko introduced a new design philosophy called the Evolution 9 Style. It was based, of course, on the Grand Seiko Style which has always defined the design of all Grand Seiko watches and continues to do so. The Evolution 9 Style preserves the fundamentals of the Grand Seiko Style but adapts them for a new generation by setting new standards of legibility, comfort and beauty. Ever since its creation in 1960, Grand Seiko has evolved continuously as new technologies, materials and ideas have opened up new design possibilities and the Evolution 9 Style is another step forward on this never-ending road. It was developed to further refine the aesthetics that have been at the heart of Grand Seiko from the start and to renew them for the years to come. --- Exterior Exterior: High-intensity titanium Case back: Glass Material: Box shaped sapphire crystal Glass Coating: Anti-reflective coating on inner surface LumiBrite: LumiBrite on hands and index(es) Case size: Diameter 41.0mm Lug-to-lug 48.3mm Thickness 13.9mm Band width: 22mm Clasp type: Three-fold clasp with push button release The perimeter of Band: 192mm Movement Caliber no.: 9R66 Instructions Movement Type: Spring Drive Power reserve: Approx. 72 hours(3 days) Accuracy: ±1 second per day / ±15 seconds per month (average) Functions Water resistance: 10 bar Magnetic resistance: 4,800 A/m Other details / Features: Screw-down crown Allergy-safe metal 30 jewels 24-hour hand (dual time...
