PROSPEX 1968 HERITAGE DIVER'S GMT U.S. LIMITED EDITION SPB477

1968 Heritage Diver's GMT U.S. Limited Edition. 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 dial features a date calendar, gold GMT hand, and large LumiBrite markers and hands for enhanced legibility. Crafted of stainless steel with super-hard coating and following ISO standards 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. 200m Water Resistant
