SPB519J1 Seiko Prospex 1968 Heritage Diver’s GMT 60th Anniversary

This design commemorates 60 years of Seiko’s heritage in innovative and reliable diving watches, which began with the 1965 launch of Japan and Seiko’s first ever Diver’s watch.

This latest timepiece takes its inspiration from a key milestone in Seiko’s diving watch expertise – the 1968 Diver. This was the brand’s first one-piece case hi-beat Diver’s watch, with 300m water resistance.

This 2025 re-interpretation is crafted from stainless steel with a super-hard coating, the diving scale on the bezel is lightweight – crafted in scratch-resistant ceramic and its GMT feature tracks two time zones simultaneously. For the first time in a Prospex watch, the short-pitch length bracelet features a micro-adjustable clasp feature for added comfort.

The in-house built 6R54 automatic GMT calibre is accurate to -15/+25 seconds per day, with a three day power reserve. This timepiece is water resistant up to 300m.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
