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 a 300 meter water resistance. 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 adjustment. 1968 Heritage Diver’s GMT Blue ceramic uni-directional rotating elapsed timing bezel Clean sunray finish white dial with red accents Automatic GMT with manual winding capability Red 24-hour hand Date calendar LumiBrite hands and markers Screwdown crown and caseback Tri-fold push button release clasp with secure lock and slide adjuster Comes with the box and all the papers, never worn, ships right away.
