The SPB143 pays homage to Seiko’s very first dive watch, the legendary 62MAS from 1965. But make no mistake—this isn’t just a retro rehash.

The brushed and polished finishes give it a premium look without screaming for attention.
Understated Yet Striking Design
One of the SPB143’s biggest strengths is its dial. It’s a deep, slate gray with a subtle sunburst texture that plays beautifully in different lighting. The applied indices and hands are generously filled with Seiko’s proprietary LumiBrite, which glows like a torch in low-light conditions.
There’s a tasteful date window at 3 o’clock—easy to read, yet unobtrusive. The overall design is restrained, minimal, and timeless. This is a dive watch you can easily wear with a suit or a wetsuit.
Built to Go Deep
