Omega Seamaster 300 & its Variations

There are several broad variations for the Omega Seamaster 300 from the 1960s. One is the 165.024 no date version and the 166.024 date version. Another important one is the Big Triangular with fixed lugs made for the military use.

For the Omega civilian versions, there were some differences in the Omega Seamaster 300 165.024 as well namely:

1. Cases were made by Huguenin Freres (HF) and Centrale Boites (CB

2 Baton hands versus Sword hands

3. Naiad non screw down crown versus deep screw down crown.

4. Big triangle vs small on dial. The Big triangle version commands a premium over the smaller one as it was earlier and much rarer.

5. Movement ; There are two movements for the Non date version (Cal 550 for the US market, and the 552 for the European markets and Asia. For the Date version, the movement should be Caliber 565. There are two dates colours namely white and Black.

6. Watchco version : This is a version NOT original factory manufactured or assembled but being assembled using Omega Original parts for the Omega Seamaster 300 plus using the Movement 550, 552 and other movements from other Omega watches. The prices of these are almost half of the original so collectors will need to be careful in their hunt as most vintage watch collectors will avoid collecting these.

Like any watches that were produced for several years, there were also versions using the cross over parts. For example, there were examples where the hands were the earlier baton hands versus the later swords hands. There are also variations in the bezel's fonts.
