This is just me looking at the second hand compared to my internet time. I do not have any measuring equipment, however last time I was at my AD he put it on the machine and below are the results.
I was asked to not wear the watch for 24 hours, just let it sit (I am assuming to let it wind down a bit) and check. I did. The results are it was (again just from my eyes looking at the second hand versus my phone) a +1 second. It was on a stand, dial up (actually with my watch stand it’s not completely up, almost at a 45 degree angle, but close to “up”).
I have no idea what this means... but PLEASE don’t ask me not to wear my Rolex for 24 hours again  |
Many thanks for your efforts!
Your AD data explain as follows:
From left column to the right column: watch position; rate (s/d), beat error (ms), amplitude (degrees)
Bottom line shows the averages = SUM:6
Amplitudes:
Dial up & dial down: 278, 279 degrees:
both values very close (excellent)
All other positions: 249-251 degrees:
all 4 values very close (excellent)
Conclusion:
this movement has no issue at all, I understand that these data were taken
after full winding.
That your watch is running "
a consistent (approximately) - 1.4 or -1.5 seconds a day" is given by your wearing pattern, absolutely nothing to worry about. Some owners prefer that their watches run slightly + instead of -, but that's only a matter of taste
