Introduced in 1957, the Omega Seamaster 300 was conceived as a true professional dive instrument, developed for military and civilian use rather than as a lifestyle sports watch. Over the years it evolved technically and aesthetically, and the reference 165.024 represents one of the most mature and desirable executions of the model.

This example dates to 1968 and features the highly sought-after CB (Centrale Boîtes) case, appreciated for its sharper edges and more angular geometry compared to other case makers. The stainless steel case is unpolished, retaining its original proportions, crisp lines, and correct thickness—an increasingly rare and decisive factor for serious collectors. The screw-down crown reinforces the tool-watch DNA and ensures proper functional integrity.

The bakelite bezel has an awesome patina, and with clear, well-defined numerals and minute scale. The dial remains clean, balanced, and extremely legible, staying true to the original purpose-built design that made the Seamaster 300 a benchmark among professional divers.

Powering the watch is the Omega cal. 552, a self-winding movement widely regarded as one of Omega’s most robust and reliable no-date calibers of the 1960s. The watch is fitted with the correct Omega steel bracelet reference 1171 with 633 end links, completing a coherent and period-correct configuration.
