Founded in 1881 in Tokyo, Seiko has a long-standing reputation for producing highly reliable professional dive watches. In 1965, Seiko introduced Japan’s first diver’s watch, marking the beginning of a legacy that would influence dive watch design worldwide. The Diver’s Watch 55th Anniversary Limited Edition celebrates this heritage by honoring Seiko’s earliest professional dive models with a faithful modern reinterpretation.

The Seiko Diver’s Watch 55th Anniversary Limited Edition, reference SLA039, features a 44.3 mm stainless steel monobloc case inspired by the iconic 1968 professional diver. The deep blue dial with applied hour markers and bold LumiBrite hands offers exceptional legibility, while the overall design reflects Seiko’s classic tool-watch aesthetics. Powered by the in-house Seiko caliber 8L35 automatic movement, it delivers a 50-hour power reserve, a frequency of 28,800 vph, and functions including hours, minutes, central seconds, and a date display at 4:30.

A dual-curved sapphire crystal with anti-reflective coating ensures durability and clarity, while the unidirectional rotating bezel provides precise dive timing. With 300 meters of water resistance, a screw-down crown, and Seiko’s proven professional diver construction, this watch is engineered for demanding underwater use. 

This Seiko Diver’s Watch is in near mint condition and comes as a full set.
