Seiko Prospex 1968 Heritage Diver’s GMT HBC001 & HBC002: Full Review & Upgrades (2026)

Seiko's Prospex 1968 Heritage Diver's GMT collection has been making waves in the watch world, and the latest additions, the HBC001 and HBC002, are a testament to the brand's commitment to innovation and design. These new models, available in classic black and a rich green colorway, offer a fresh take on a beloved classic, with some significant upgrades that are sure to delight watch enthusiasts.

A Timeless Design, Reimagined

The stainless steel case, measuring 42mm in diameter and 13.3mm thick, pays homage to Seiko's iconic 1968 professional diver's watch. The sharply defined surfaces and mirror-polished sides give the watch a modern, sleek look, while the screw-down crown and unidirectional bezel with a knurled edge provide a sturdy, functional feel. One of the key updates is the increased water resistance, now at 300m, bringing it closer to the specifications of a true professional dive watch.

Legibility and Style

Both the HBC001 and HBC002 excel in legibility, a crucial aspect for any diver's watch. The large applied indices, broad hands, and generous LumiBrite ensure excellent visibility, even in low-light conditions. The GMT hand, with its luminous triangle tip, adds a touch of sophistication, while the discreet date display maintains a clean, uncluttered look. The green dial of the HBC002, though challenging to capture in photos, adds a unique, vibrant element to the watch's aesthetic.

Powering the Precision

Seiko's Calibre 6R54 automatic movement with manual winding powers these timepieces. This movement offers a practical GMT function, allowing for the display of a second time zone via the independently adjustable 24-hour hand. With a frequency of 21,600 vibrations per hour and a 72-hour power reserve, the watch ensures accurate timekeeping and a reliable performance.

Bracelet and Clasp: A Welcome Improvement

The stainless steel bracelet, a signature of the collection, has been enhanced with a redesigned three-fold clasp. This clasp incorporates a slide-adjustment mechanism, allowing for tool-free extension of up to 15mm, a welcome feature for divers and those who prefer a more customized fit.

Final Thoughts

The Seiko Prospex 1968 Heritage Diver's GMT HBC001 and HBC002 are a testament to the brand's ability to blend classic design with modern functionality. With their increased water resistance, improved clasp, and elegant aesthetics, these watches are a worthy addition to any collection. Personally, I find the attention to detail and the subtle improvements made to these timepieces truly impressive. It's a great example of how a brand can stay true to its heritage while continuously pushing the boundaries of design and innovation.
