Hi I bought a seamaster 150m with cards etc from a private seller. First time watch owner. Just wondering would anyone know what year it is likely to be and if its a good watch.Seller didn't know.

 

We dont know much about those (not vintage). Better go here: https://omegaforums.net/forums/modern-omega-watches/

 

As above, better in the modern side.

If it has the cards but its not dated, is the serial number on it?

 

circa 2005, I have the same one
