The dial is in excellent condition and retains its original luminous material. The broad arrow hands were refilled with tritium and have aged naturally over time. This appears to have been done in the 1970’s according to our observation.
The bracelet is also an Omega USA service bracelet from the 70-80's as the original bracelet likely broke as was common on these fragile original bracelets.
The movement was fully overhauled by Omega in 2015. The crown was replaced, but the original ‘narrow feet logo’ crown was returned and is included with the watch with the Omega warranty card. The case appears to have been polished once, but the lugs are still thick and retain original finishing.
The Bezel was restored by Omega during the last service as well.
The overall conditon of this watch is great and a stunning piece.

NOTE: This rare Seamaster 300 comes complete with Omega archives confirming delivery to the US ARMY via EES (European Exchange Services) in 1959, which is a very rare provenance. It is not a military issue watch.

The Seamaster was launched by Omega in 1948 to coincide with the brand’s 100th anniversary and is the oldest model in the current collection. Loosely based on the waterproof wristwatches made for the British military at the end of World War II, the Seamaster was first intended as a robust yet elegant watch for active individuals who wanted a watch for ‘Town and Country’. The first watches were equipped with self-winding movements in both standard and chronometer versions, the latter being universally appreciated for their robustness, accuracy and reliability.
The key to these watches was the O-ring gasket. At this time, water-resistant watches generally used lead or shellac gaskets which were susceptible to temperature changes. The Seamaster, however, used a rubber gasket of the type that had proven its abilities in submarines during the Second World War. The Swiss Laboratory for Watch Research independently tested 50 cases of the Seamaster at a simulated depth of 60 meters. After temperature changes of -40° C to 50° C in quick succession, the cases showed no sign of water infiltration. The engineers at OMEGA were so sure of the Seamaster that one flew over the north pole attached to the outside of a DC6 in 1956.
The following year saw the introduction of the “Professional” range of Seamaster watches with the launch of the Seamaster 300.
