SEIKO PROSPEX HBC001J1 1968 HERITAGE AUTOMATIC GMT DIVER'S MEN WATCH
Seiko Prospex HBC001J1 — 1968 Heritage Automatic GMT Diver's Watch
The Seiko Prospex HBC001J1 is a modern re-interpretation of the legendary 1968 Diver's watch — Japan's first hi-beat one-piece diver's watch, and the foundation of Seiko's sixty years of diving watch innovation. The HBC001J1 honours that heritage while making one bold design statement of its own: a rich green dial that gives this milestone timepiece a distinctive character that the black dial HBC002J1 does not share. Powered by the in-house 6R54 calibre — the first movement with mechanical GMT capabilities ever used in a Seiko dive watch — it is a landmark piece for the serious Prospex collector.
Built for professional and recreational divers who demand both precision and wearability, the HBC001J1 pairs a 42mm stainless steel case with a Japanese ceramic unidirectional rotating bezel, sapphire crystal, and 300M water resistance. The bracelet is engineered for comfort with a low centre of gravity and short-pitch construction, while the three-fold clasp with solid and slide adjuster allows incremental fit personalisation. A three-day power reserve and Lumibrite on hands and markers complete a specification that performs as impressively in the field as it looks on the wrist.
Key Features
- Seiko 6R54 automatic movement with manual winding — the first mechanical GMT calibre used in a Seiko dive watch
- GMT function — mechanical 24-hour GMT hand independently settable to a second time zone
- Approx. 72-hour (3-day) power reserve — reliable performance through a long weekend without wearing
- Accuracy: +25/-15 seconds per day — reliable automatic timekeeping
- 300M Diver's water resistance — built to professional diving standards
- Japanese ceramic unidirectional rotating bezel — scratch-resistant, precise, and purpose-built for dive timing
- Sapphire crystal — premium scratch resistance and superior optical clarity
- Lumibrite on hands and hour markers — superior legibility in low light and underwater conditions
- Green dial with baton markers — bold, distinctive colourway that sets this variant apart
- 42mm stainless steel case — substantial dive watch proportions with a 13.3mm slim profile
- Screw-down crown — water integrity protection for diving use
- Date display — everyday practicality built in
- 24-hour hand indicator — dual time zone reference at a glance
- Stainless steel bracelet with low centre of gravity and short-pitch construction — engineered for all-day comfort
- Three-fold clasp with secure lock and push-button release — solid and slide adjuster for a personalised fit
Why You'll Love It
The HBC001J1 is the bolder of the two 1968 Heritage GMT variants — and for those who gravitate toward green dial dive watches, it is the definitive choice. The green dial gives the 1968 heritage design a contemporary energy that feels fresh without departing from the purposeful, tool-watch character of the original. The 6R54 mechanical GMT movement remains a genuine first for the Prospex dive line, the ceramic bezel is virtually unscratchable in daily use, and the 300M water resistance means it is genuinely ready for the dive. The three-fold clasp with solid and slide adjuster and low centre of gravity bracelet make it one of the most comfortable dive watches to wear all day on land as well as underwater. A landmark Seiko Prospex — in the colour that collectors will remember.
HBC001J1 vs HBC002J1 — Which Should You Choose?
Both models share identical specifications — the same 6R54 mechanical GMT calibre, 42mm stainless steel case, Japanese ceramic bezel, sapphire crystal, 300M water resistance, 72-hour power reserve, and Lumibrite. The only difference is the dial colour. The HBC002J1 features a classic black dial — versatile, authoritative, and the more traditional dive watch choice. The HBC001J1 features a rich green dial — bold, distinctive, and increasingly the choice of collectors who want something that stands out. Both are equally capable. The choice comes down entirely to the dial.
The Seiko Prospex Story
Prospex is a combination of the words "Professional" and "Specifications." Seiko Prospex timepieces are designed to be practical, reliable, and durable — built to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. The 1968 Diver's watch was a turning point in that story — Japan's first hi-beat one-piece diver's watch set the standard for what a professional dive watch could be, and the HBC001J1 carries that sixty-year legacy forward with the most technically advanced movement ever fitted to a Seiko dive watch.
Backed by Seiko's official warranty. Authentic Seiko Prospex watch, sold by authorised retailer City Chain Singapore.
