It’s probably a 2576 ref dating to 1948-51 or so, one of the first Seamasters. The numeral style isn’t terribly uncommon. As mentioned, movement and caseback will confirm.
Hello everyone!
Thanks for your return, unfortunately I'm afraid that we'll never know...
The watch is now reserved and the seller can't open the back
I am a little disappointed because it has a very nice appearance! 🙁
