I did not like my PAM 312 which I had for only 1 year. It was 1 of 3 watches, a SS submariner and a two tone Daytona. The PAM was only worn a few times per week but was always about 3 minutes faster then the other watches. It would do this after just 2 days, and I reset many times and it happened every time.
This happened whether I had it on a winder or not. Also its reserve was much less then the rolex's even though it was supposed to be more.
It also started showing many scratches on the polished parts.

 

Then the 339 is the answer but all of them are 16k + that I can see.

 

Peter....thanks and LOVE the watch
