Hi Peter,
the hacking function of the watch by means of the crown is best described here. I've pulled out the relevant section.

Hacking a watch, you are correct, is not great on the movement, Weems came up with a solution in the second setting watch.
I've also added an advert for the Longines Weems at the time, which I thought might be of interest.
