I'm looking to make my first vintage purchase but don't have a deep vintage knowledge set to tell if I'm getting a reasonable deal (or legitimate watch for that matter). Seller offering a manual gold/ss seamaster DeVille for ~$900 (negotiating). Listed as festuring a manual wind 601 caliber movement and serviced last month. I've messaged for additional pictures of the movement next. Any thoughts on this piece? The price?

 

Crown is a replacement. Caseback looks overpolished. Watch seems genuine.

 

Strap and buckle are both counterfeit.

 

Do you think that's a fair price?

 

What's "fair"? I think it's in line with retail prices for casual buyers.

 

Thanks, that's what I was asking
