Using the AceTimer Timegrapher 1000, testing Vintage Cartier Tank LC, Frederic Piguet Cal 99P, 21,600 beat reate, lift angle 52 (not sure if this is correct), test period = 4 seconds. Here are the results, what do they mean?
Position Rate Deviation Amplitude Beat error
Face Up -8, -4, -5, -10, -9, 249-261 .3
Crown Up -6, -8, -2, -1, -8, -7 229-242 .2
Crown Dn -5, -1, -7, -10, -8, -5 225-233 .2
Crown R -22, -21, -13 237 .4
Crown L +8, +7, +0, +1, +4 236 .1
What do thest mean, as I left the watch on each position for about a minute or two the Devation rate (seconds per day), kept changing. Why did these value keep changing? Watch was fully wound.
Any explanation is deeply appreciated.
