Seiko Prospex Marinemaster 1968 Heritage Diver HBF001 and HBF002 are two mechanical dive watches developed by Seiko as part of its Prospex Marinemaster line. The models reinterpret the brand’s 1968 high-beat diver’s watch, maintaining its case silhouette and 4 o’clock crown position. The lineup includes a standard black HBF001 and a limited HBF002 created with JAMSTEC. Both watches are powered by the in-house Calibre 8L45 automatic movement, offering a 72-hour power reserve and improved accuracy rated between +10 and -5 seconds per day.
The watches use stainless steel cases measuring 42.6 millimeters with a unidirectional ceramic bezel and 300-meter water resistance. The HBF001 features a fine-grain black dial designed to reduce light reflection, while the HBF002 includes a textured blue gradient dial inspired by icebreaker paths. Both models use LumiBrite-filled hands and markers, a sapphire crystal, and a three-link bracelet with a micro-adjustment clasp system.
