Diver’s 1968 300M Heritage GMT 42mm Mens Watch Black

Latest upgraded 1968 Heritage Diver’s GMT. Seiko Prospex challenges every limit with timepieces created to exceed expectations, engineered with superior style and innovative technology for the sea, sky or land. Part of a rich legacy of innovation in high-intensity timekeeping, Prospex continues to celebrate a long history of sports watch expertise with re-creations and re-interpretations of landmark achievements. This extraordinary timepiece, re-interpreting Seiko’s landmark 1968 diver’s watch, showcases the brand’s first mechanical GMT movement in a diver’s watch, caliber 6R54. 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, providing a second time zone reading at a glance. Framed by a Made-in-Japan black ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the black dial features a date calendar, gold GMT hand, and large Lumi Brite markers and hands for enhanced legibility. Crafted of stainless steel with super-hard coating, with an upgraded water resistance of 300 meters, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, sporty three-link bracelet, and a slide adjuster clasp for the perfect fit.
