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

Seiko's Evolution: Why the Prospex 1968 Heritage Diver’s GMT HBC001 and HBC002 Matter More Than You Think

Seiko has always been a brand that walks the fine line between heritage and innovation, and their latest additions to the Prospex 1968 Heritage Diver’s GMT line—the HBC001 and HBC002—are no exception. On the surface, these watches might seem like incremental updates to an already successful collection. But if you take a step back and think about it, they represent something far more significant: Seiko’s quiet yet deliberate evolution in the competitive dive watch market.

The Design: A Nod to the Past, A Leap Forward

One thing that immediately stands out is how Seiko has managed to preserve the essence of the 1968 original while injecting modern functionality. The 42mm stainless steel case, with its sharply defined surfaces and mirror-polished sides, feels both timeless and contemporary. Personally, I think this is where Seiko excels—they don’t just replicate the past; they reinterpret it. The ceramic bezel, for instance, isn’t just a stylistic choice; it’s a practical upgrade that enhances durability and legibility.

What many people don’t realize is that the increase in water resistance from 200m to 300m isn’t just a number. It’s a statement. Seiko is positioning these watches closer to their professional dive watch specifications, bridging the gap between tool watches and everyday wearables. This raises a deeper question: Are these watches still just for divers, or are they becoming something more versatile?

Colorways That Tell a Story

The HBC001 and HBC002 come in classic black and green, but don’t let the simplicity fool you. The green dial, in particular, is a detail that I find especially interesting.
