I am going to buy a vintage Omega Seamaster cal 501. It is 17 jewels unadjusted movement (writen on the movement). Is it authenthic piece? I need some advises before make a decision whether I should buy it or not. And here are some pictures of the watch.... Thank you View attachment 634468 View attachment 634472

 

It's authentic but it's a very bad redial. I'd pass.

 

Thank you Gordon. But may I know what makes you judge that it's authentic but redial piece, please?

 

All the text is in the wrong font and minute hashes are wrongly sized. In addition, the seconds hand is incorrect.

 

I see, CoElPueblo.... And how about the movement? Was Omega produce the 501 in 17 jewels variant?

 

Hmm, I don't think so. The 17 jewel version is called cal. 500 and was primarily for the US market. The rotor with the "17 jewels" could be a replacement from a cal. 500.

 

I agree. That's what in my mind, too. Thanks alot. Very informative and helpful.
