The Seiko Marinemaster 1968 Heritage Diver’s JAMSTEC Limited Edition HBF002J1 is a special collaboration model created with the Japan Agency for Marine-Earth Science and Technology. Limited to 1,000 pieces, it combines professional dive performance with inspiration drawn from Arctic exploration.

The blue textured dial evokes the path of an icebreaker through frozen seas, symbolizing discovery and the depth and clarity of Arctic waters. LumiBrite-coated hands and indexes ensure excellent legibility in all conditions.

The 42.6 mm stainless steel case features a ceramic unidirectional bezel and a durable Super-Hard Coating. A curved sapphire crystal with anti-reflective coating protects the dial. The screw-down crown and robust construction ensure water resistance up to 300 meters.

At its core is Seiko’s automatic 8L45 movement with approximately 72 hours of power reserve and manual winding capability. The movement offers a daily accuracy of approximately +10/-5 seconds and includes a stop seconds function and date display.

The stainless steel bracelet features a three-fold clasp with safety lock, push-button release, micro-adjustment and a diver’s extension. The lug width is 20 mm and magnetic resistance is 4,800 A/m.
