Seiko Prospex Marinemaster JAMSTEC Limited Edition Watch HBF002J1

The Seiko Prospex Marinemaster HBF002 (limited to 1,000 pieces worldwide) celebrates Seiko's long-standing partnership with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). Housed in a 42.6 mm stainless steel case treated with Seiko’s super-hard coating, it showcases a multi-dimensional blue gradient dial with a textured ice-carved motif inspired by polar research icebreakers like the Mirai II. Driven by Seiko's high-grade 35-jewel in-house Caliber 8L45 automatic movement, it delivers an extended 72-hour power reserve and top-tier accuracy. Shielded by a dual-curved anti-reflective sapphire crystal and a scratch-resistant blue ceramic bezel insert, this flagship diver is completed by a steel bracelet with an on-the-fly micro-adjusting clasp and professional 300 meters of water resistance.
