$8800A Spring Drive Powered Diver's WatchThis diver’s watch is powered by Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring with the high precision of a quartz watch.The case and band are made with high-intensity titanium, providing a scratch and corrosion resistant finish with a 137g weight reduction, making it 30% lighter than stainless steel and a pleasure to wear. The watch is water resistant to a depth of 200 meters and utilizes LumiBrite for increased visibility of the hands and index. Designed for use in some of the most unforgiving environments, the rotating bezel is removable for simple maintenance while the area around the crown has been crafted to ensure that residue from dirt, sand, or seawater can be easily washed off.With a mirror-finished case achieved through Zaratsu polishing, a lustrous rotating bezel, and multi-faceted cut indices, this watch is unmistakably Grand Seiko in its appearance, high specifications and durability.SPECIFICATIONSCase										Case :			High-intensity titanium											Glass :			Sapphire crystal											Coating :			Anti-reflection coating on inner surface											Lumi Brite :			Hands and markers											Case size :			Diameter 44.2mm×Thickness 14.0mm											The perimeter of bracelet :			196.0mm											Band :			and ceramic			Movement						Movement :			Caliber 9R65    Instructions 											Driving system :			Spring Drive											Power reserve :			Approximately 72 hours											Accuracy :			±1 seconds per day (±15 seconds per month)			Functions/Specifications										Clasp :			Three-fold clasp with push button release											Water resistance :			Water resistance for air diving 200m											Magnetic resistance :			4800 A/m (60 gauss)											Weight :			137.0 g											Remarks :			Screw down crown			Screw back			Jewels: 30			Power reserve display function			The unidirectional rotating bezel			Caseback with a lion emblem			 $8800 CAD3 YEAR WARRANTY AUTHORIZED DEALER
