All, what is market for a good condition Seamaster 2255.80, and what do most consider minimum for verification of ahthenticity?

1. Is a picture of the movement good enough? It looks pretty intricate, and unlikely to be attempted
2. Should it absolutely have a serial number?
3. Any other thoughts are appreciated. This would be my first Omega

Thanks,

Clay
