My PAM Base ETA 6497 has been "losing" time on the Power Reserve. Let me explain myself.
When I first purchased it I would get around 66 hours on a full wind. By full wind, I mean turning the crown until a point where it no longer winds and without forcing any further.
I've been doing this test once again for a few times and would get different results each time.
1st try: 66 hours
2nd try: ~63.5 hours
3rd try: ~61.7 hours
I cannot find an answer as to why I would be getting back different PR even with a full wind.
I know that these are way over the stated 48 hours, but I am just curious as to know why these figures would not be consistent.
Thanks
