I also use it for performing the damping test on automatic rotors with bearings, to check the condition and cleanliness of the bearing, ensuring that it meets the specs on this test by timing how long it swings for:



I also use it when performing high pressure wet testing, to time how long the case has been at various pressure stages in that process:



And how long it has been on the heater:

If I don't have the Speedmaster on, I use whatever watch I have on, but this is much easier to do with a chronograph, in particular the damping test where I have to watch the rotor swinging to know exactly when it stops...
