So I've never seen anyone use Allan deviation to meausre the stability of a mechanical oscillator, but I wonder if it wouldn't be useful. Obviously the long-term stability in mainspring watches will be very poor as the power winds down, but what kind of stability would be expected in the short-term? I assume you'd want to use full oscillations rather than half oscillations, since otherwise the beat error will dominate.
