A 32xx watch can still run very accurately although the caliber suffers from too low amplitudes, this is measurable (with a timegrapher) after full winding (t = 0) and at t = 24 hours.

The main observables are the caliber amplitudes in all 3 vertical watch positions. By opening the caseback you have no chance to 'see' that.

I agree with you that +1 s/d is a 'fine performance'.

I installed the Timegrapher app on my iOS phone and can take measurements for the community. Please tell me how to do it correctly. The app indicates that it is too noisy (but it's actually quiet) and where is the best place to place the watch. I will share my results with the community.
