The Seiko Prospex Marinemaster JAMSTEC Limited Edition 1968 Heritage Reinterpretation Automatic Men's Watch HBF002J1 is a professional-grade dive watch celebrating Seiko's legendary diving heritage and its partnership with JAMSTEC (Japan Agency for Marine-Earth Science and Technology). Inspired by the 1968 Seiko Hi-Beat Diver's Watch and Japan's icebreaking research vessel Mirai II, this exclusive limited edition features a stunning blue gradient dial that represents the vessel's trail through polar ice. The dial is finished with polished transparent layers and a satin texture to maximize underwater legibility while minimizing reflections. Powered by Seiko's premium in-house Calibre 8L45 automatic movement with manual winding capability, it delivers exceptional accuracy, a high-beat frequency of 28,800 vibrations per hour, and an impressive 72-hour power reserve. Built to ISO diving standards, the 42.6 mm stainless steel case features a super-hard coating, dual-curved sapphire crystal, ceramic bezel insert, screw-down crown at 4 o'clock, and professional 300-meter water resistance, making the HBF002J1 an exceptional collector's piece and a true professional diver's watch.
