SM 60-hour power reserve is a false claim

Winding it until some arbitrary 'resistance' point is reached is just that, arbitrary. Whenever I check an automatics power reserve I wind the crown 50 or 60 times, then put in a few more for good measure, I always get more run time than the spec says. You have to make sure you have a full wind in order to make the claim that something is deficient, r.e. runtime. Wind 'em up fully and report, I bet you don't have a problem.

Are you running the chronograph function? Because that will affect the power reserve .
No I don’t. If someone has an idea of what the power reserve depends on it would be very helpful.

Bottom line if it has a feature, any feature, and it doesn’t work accurately then it should.

Ummmmm, if it was simply winding then you would have the same outcome +/- some (small) degree of divergence.

Put it on a winder and see how long it lasts.

Seriously, I've misinterpreted some timegrapher readings by not having wound the watch sufficiently. Look up the number of turns required and double it. Then make sure what you think is a turn is actually a turn.
