For dannyp
Here is a nice example of two combined (Timegrapher + WatchTracker) measurements, along the entire power reserve, until the 3285 movement stopped running. For both tests, the watch was all time at rest in dial up position. The experiment was done by Charles.
One can see:
- Excellent time keeping until about 69 hours (see Watch Tracker curves).
- The watch GAINED time during the amplitude decreases in both tests.
- But this behavior is NOT necessarily identical for all 32xx calibers.
