Launched in 1948, the first Seamaster was quite different from the diver’s watches we associate with the name today. While the historically important initial models were a significant achievement for the time, it wasn't until the introduction of the Seamaster 300 in 1957 that features commonly linked with diver’s watches emerged, such as the revolving bezel and the black luminous high-legibility dial. Officially rated water-resistant up to 200 meters, the Seamaster 300 is fitted with a bidirectional bezel graduated for 60 minutes and luminous hands to enhance readability.

The present Seamaster 300 reference CK 2913-4 stands out not only for its iconic “Broad Arrow” —often lost to various services over the years—but also for its appealing condition, particularly the dial and original Bakelite bezel. The luminous material has developed an attractive ivory hue, and high radium readings on the Geiger counter indicate that the lumes have been well preserved over the years.

The Seamaster is the Omega model with the longest production run and remains in production today. The reference 2913 is among the most sought-after timepieces in this line due to its status as a precursor to this enduring lineage. Accompanied by an Extract of the Archives confirming that the watch was originally delivered to the United Kingdom, this is a rare opportunity to acquire an original condition Seamaster CK 2913-4.
