Fully Serviced Asian 6497 Losing Time

[vlydog]

I have a PAM 219 with a fully serviced Asian 6497 that is losing about 15 minutes a day. Can anyone tell me what might be the problem?

Thanks.

Check the hair spring.. sometimes an impact can cause the spring to hang up on the mounting posts.

Tangled hair springs make it run fast.

Vly-

I recently experienced something similar; I cased up my 6497 and noticed it was losing a few minutes for every 6 hours. I uncased the movement to give everything a visual once over, recased again and everything is now running fine. I have a feeling that one of the plates or bridges may have had some pressure applied to the gear train or was somehow pinched, hence causing inaccurate time keeping.

Not sure if this would apply to yours, but figured it would be worth at least a mention...

Update:

After 12 hours of wrist time I noticed that the watch lost approximately 45 minutes. Now after being still in the watch box for the last 24 hours it appears to be keeping perfect time. So it looks like I have a problem of an intermittent nature. Does any one else have clues as to what is going on?
