This is currently up for auction. I'm a bit of a newbie and won't be bidding, but am looking for advice on verifying watches online. I'd appreciate it if someone could point out whether this example is legit or not, and provide resources I could study to do future verification on my own. Thank you!

In 95% of these requests the watch is fake. This is no exeption. Good you asked before you bought it 😀

https://www.omegaseamaster300.com is your ressource to learn more.
Thank you for the resource. What specifically did you see in this example that let you know it was fake? From what I can see, maybe the case back?

The fake aging of the bezel numerals is outrageous.

Uh, read all the Threads here on this Forum concerning Seamaster 300 and Look at hundreds of confirmed originals.

OR

Pay someone who HAS learned the differences and be assured it is an original when you buy it from them.

The later will cost you more, the former will allow you to pounce when one pops up, beating all your competition.
