Seiko Prospex Marinemaster HBF002J1 JAMSTEC Limited Edition Watch
Celebrate Seiko’s heritage of ocean exploration with the Seiko Prospex Marinemaster 1968 Heritage JAMSTEC Limited Edition (Ref. HBF002 / HBF002J1), limited to 1,000 pieces worldwide. Created in partnership with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), this flagship diver features a 3D-textured blue gradient dial inspired by the tracks carved through Arctic sea ice by icebreaking vessels, protected under a polished, high-clarity coating.
Framed by a glossy blue ceramic bezel insert and a super-hard coated stainless steel case, this watch incorporates the iconic 1968 diver silhouette with a 4 o'clock crown. It is powered by the hand-assembled Caliber 8L45 automatic movement—based on Grand Seiko architecture—delivering an upgraded 72-hour power reserve and improved accuracy. Built for professional underwater performance, it features 300m diver’s water resistance, a dual-curved anti-reflective sapphire crystal, and an updated sliding micro-adjusting clasp for maximum comfort.
