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. Driven by rich legacy that has set the standard for dive watch specifications and a heritage of iconic design, Prospex continues to keep going forward with precision timekeeping, crafted for the modern world. This exceptional timepiece reimagines Seiko’s landmark 1968 diver’s watch, and is updated with greater water resistance, following ISO standards for scuba diving depths of up to 300 meters. Framed by a Made-in-Japan navy-blue ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the sunray finish white dial features a date calendar, red GMT hand, and large LumiBrite markers and hands for enhanced legibility. Providing an upgraded power reserve of approximately 72 hours, the 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. Crafted of stainless steel with super-hard coating, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, as well as a specially developed slide adjuster clasp allowing for easy size.
