Measurement Procedure
For everybody joining new in the fun of caliber investigations using a timegrapher, I recommend the following steps:
(1) Measure your watch in 5 positions (except 12U) and note rates, amplitudes, and beat errors.
(2) Start with full watch winding, place the watch on your timegrapher, in DU position.
(3) Wait (10-15 minutes) for stabilisation.
(4) Start timegrapher measurement, which usually takes about 1 minute.
(5) Change watch position, wait (2-3 minutes), measure.
(6) This you do sequentially for all 5 positions.
(7) Save all data in an Excel file.
(8) Calculate average values and error bars (standard deviation).
(9) Save file.
(10) For long term measurements, leave your watch (at rest) in DU position on the timegrapher, repeat the sequence in certain time intervals.
Note: The more data the better; with 0, 24 h, 48 h … you will miss to detect some caliber characteristics, e.g. a fast decrease in amplitudes after full winding.
Following this simple procedure will allow us to obtain comparable data sets, which could be visualized in graphs, as done previously in this thread.
