Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. This extraordinary timepiece, available in a controlled production run of 500 pieces, honors Seiko’s landmark 1968 Diver’s Watch and showcases the brand’s first mechanical GMT movement created for diving, caliber 6R54. Extending the theme of duality with functionality in the sea and on land, the dramatic vertically gradated dial reflects the view from above and below the water. Providing a power reserve of approximately 72 hours, the longest of any Seiko mechanical watch, this 24-jewel automatic GMT movement beats at a frequency of 21,600 vibrations per hour and offers manual winding capability. The GMT hand can be set independently in one-hour increments, without interrupting the time-of-day hands, to provide a second time zone reading at a glance. Framed by a Made-in-Japan black ceramic uni-directional rotating elapsed timing bezel with a knurled edge for enhanced operability, the rich blue-green dial features a date calendar, bronze-tone GMT hand, and large LumiBrite markers and hands for enhanced legibility. Crafted of stainless steel with super-hard coating and built for scuba diving to depths of 200 meters, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, three-link slim profile bracelet, and a tri-fold push button release clasp with secure lock and extender. 1968 Heritage Diver’s GMT U.S. Limited Edition Limited Edition of 500 The dramatic vertically gradated blue-green dial reflects the view from above and below the water Black ceramic uni-directional rotating elapsed timing bezel Bronze-tone GMT hand Serial number engraved on caseback Automatic GMT with manual winding capability Date calendar LumiBrite hands and markers Screwdown crown and caseback Tri-fold push button release clasp with secure lock and slide adjuster CASE DIMENSIONS: DIAMETER: 42.0 mm THICKNESS: 13.3 mm LENGTH: 48.6 mm MOVEMENT: Caliber 6R54 CASE: Stainless steel with super-hard coating CRYSTAL: Curved sapphire crystal with anti-reflective coating on the inner surface STRAP: Stainless steel bracelet with super-hard coating WATER RESISTANCE: 300 meters (1,000 feet), follows ISO standards and is suitable for scuba diving
