Any info on sea master, (no 300) models

robinbanks · Apr 7, 2026

I've come accross a vintage seamaster I may purchase. It has straight lugs, a missing bezel so no divers bezel but one thing I cant figure out is it doesnt say "Seamaster 300". It says "Seamaster" on the dial. Anyone know if this was an actual dial? I can't find any real info on it.

You’re going to need to post some pictures in order to get any meaningful advice.

Many (and most) Seamasters are not Seamaster 300's. As mentioned, post some pix of the dial, movement and inside caseback if you want some useful thoughts.

Take some time to educate yourself before trying to buy a vintage watch, you will be much happier if you do.
