Help with 50s seamaster please

hi all,

New to the forum but have a couple of Seamasters. One is a chrono diver and this is my other. 50s Seamster cal420. I was looking for any info about the watch if anyone can help as I’m trying to ascertain it’s year, and ultimately it’s value to go towards something else.

The watch is nice. Strap non genuine, and the dial face has a couple of minor repairs about pin head size that have been touched up but nice tidy neat job. Works as it should. I’ve had this one maybe 10 years or so now

Thanks
Tony

You can use the serial number to determine the age. http://chronomaddox.com/omega_serial_numbers.html
Looks like yours is from around 1950-51. Search for your reference number, which is located on the case back on ebay sold listings for value.

Ah yes that confirms about the age I thought. There are so many variations though to try and understand, I have seen them anything fro
£500-£2000 so really stuck trying to work out where to realistically place it.

Appreciate the help.
Tony
