[product_description]Prospex PADI Special Edition. Designed for those who treat life as the ultimate adventure, Seiko Prospex keeps moving forward, meeting every challenge with technological excellence and winning design. This stunning Special Edition celebrates Seiko’s official partnership with PADI, the world’s leading scuba diver training operation, particularly in the distinctive patterned and gradated blue dial reflecting the surface of the ocean as seen from under water as the sunlight reaches through the waves on the surface. With a magnified day/date calendar, the dial also features LumiBrite hands and markers with a unique blue glow recalling signature PADI colors, while vibrant blue accents on the blue ceramic uni-directional rotating elapsed timing bezel continue the PADI theme. Following ISO standards for scuba diving, this exceptionally durable timepiece offers a rugged stainless steel case and bracelet based on one of Seiko’s most iconic diving styles, screwdown crown and caseback, sapphire crystal with anti-reflective coating on the inner surface, and a tri-fold push button release clasp with secure lock and extender. For reliable timing in rough waters, the 24-jewel automatic movement beats at a frequency of 21,600 vibrations per hour, with a power reserve of approximately 41 hours, and offers manual winding capability. 200m Water Resistant[/product_description][unique_description_1]Technology: Automaticö|Caliber 4R36ö|21,600 vibrations per hourö|24 jewelsö|Power reserve: approximately 41 hoursö|Case Diameter (mm): 45.00ö|Case Thickness (mm): 13.22ö|Case Length (mm): 47.70ö|Case Material: Stainless steel caseö|Crystal: Sapphire crystal with anti-reflective coating on the inner surfaceö|Dial Color: Blueö|Strap: Stainless steel braceletö|Water Resistance: 200 meters (660 feet), follows ISO standards and is suitable for scuba divingö[/unique_description_1][unique_description_2]Prospex PADI Special Editionö|Special edition celebrating the partnership between Seiko Prospex and PADI, the world’s leading scuba diver training organizationö|Patterned and gradated blue dial reflecting the surface of the ocean as seen from under water as the sunlight reaches through the waves on the surfaceö|Automatic with manual winding capabilityö|Blue ceramic uni-directional rotating elapsed timing bezel with vivid blue accentsö|Magnified day/date calendarö|LumiBrite hands and markers with a unique blue glowö|Screwdown crown and casebackö|Tri-fold push button release clasp with secure lock and extenderö|ö[/unique_description_2]
