Omega Seamaster 300

In 1957, Omega released a trio of sports watches: the Speedmaster, the Railmaster, and the Seamaster 300. The (now-legendary) Speedmaster was a chronograph intended for racecar drivers, the Railmaster was an anti-magnetic watch for scientists, and the Seamaster 300 (ref. CK2913) was to be Omega’s debut offering in the still-emerging category of wristwatches for SCUBA divers

In 1964, Omega unveiled an entirely new design for the Seamaster 300 under the reference numbers 165.024. The case diameter of the Seamaster 300 increased from 39mm to 42mm, and its signature thin bezel was replaced by a much thicker one, in bakelite, with a wider insert, that featured individual minute markings the entire way around it.

The watch is equipped with an elastic bracelet ref. 1506, dated 1966 with 16 end links.
Lume is Original and the bezel insert is perfect and shiny.
