Hi,
In fact the span of the power reserve is selected so that the torque is always necessary.
When the power reserve indicator falls down to 0 the watch stops because that also means that the torque device stops the watch.
Winding from 0 the power reserve indicator till the top the torque system is freed to let the watch work!
So no problem, when the power reserve indicator goes to 0 the watch is stopped by the torque system. So you could say that the power reserve indicator works as a binary torque indicator! Yes OK when you have power reserve, no when power reserve is down!
Cheers
