Ok guys. I returned a Pam 252 a few months ago for two issues which I posted on here before. One was the W for the west designation fell off the bezel the second was a strange loss of time every half hour. I was given a replacement watch and figured I would test it out today. So I set the watch gave it a few winds until it was functioning and then slapped it on the wrist. I checked the second hand accuracy against a stop watch and it was dead on. I set the time and everything seemed fine. It has been on my wrist since 0600 hrs this morning. It was keeping perfect time or close to it all day. Now suddenly it is approximate 8 minutes slow. I don't get it. This seems to be the same problem the last one had. The movement is an A-7750. I don't understand how it can be keeping accurate time for three hours then suddenly drop 8 minutes all while being on the wrist. Any help? Should I send it somewhere? It was already tested prior to shipping out.
