# Heritage Diver Watches Seiko Drops Prospex Marinemaster 1968 Heritage Diver HBF001 and HBF002 By Amy Duong | Published 2026-03-18 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/prospex-marinemaster-1968 References: [seikowatches](http://seikowatches.com/)  [Seiko](https://www.trendhunter.com/trends/prospex-marinemaster-sla079j) 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](https://www.trendhunter.com/trends/seiko-prospex-1968-heritage-divers-gmt-spb519)-filled hands and markers, a sapphire crystal, and a three-link bracelet with a micro-adjustment clasp system.
