Seiko SPB381 Prospex Sea 1968 Heritage Diver's GMT Watch Automatic 42mm

Prospex 1968 Heritage Diver’s GMT. Designed for those who treat life as the ultimate adventure, the Seiko Prospex line meets every challenge with technological excellence and style. 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, to provide a second time zone reading at a glance. Framed by a Made-in-Japan green ceramic uni-directional rotating elapsed timing bezel with knurled edge for enhanced operability, the rich green 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, this superbly functional timepiece includes an anti-reflective sapphire crystal, screwdown crown and caseback, new three-link, slim profile bracelet, and a tri-fold push button release clasp with secure lock and extender, and follows ISO standards for scuba diving to depths of up to 200 meters. 200m Water Resistant.

Ever since its first diver’s watch in 1965, Seiko has developed new technologies, features and designs that have made the Seiko Prospex diver’s watch collection a favorite among professional and recreational divers the world over. Through more than a half-century of innovation, Seiko has continuously pushed back the boundaries of where sports watches, and diver’s watches in particular, can go and how they can be used. Continuous enhancements over the decades in safety, reliability, legibility, and ease of use have made Seiko a leader in diver’s watches. Seiko is introducing a new movement in the long-trusted 6R family that has a GMT function and a power reserve extended to a full 72 hours. Caliber 6R54 is presented in three new Prospex creations that are all modern re-interpretations of a Seiko classic from 1968 and are designed for diving with 200-meter water resistance.
