Turn the crown clockwise. As you’re winding your watch,
you will feel a slight resistance which increases as the
tension mounts.
Depending on the size of the watch, 20 to 30 forward turns
should lead to resistance.
Purely manually wound movements require winding
at regular intervals, normally on a daily basis, to keep
operating. Take care to stop winding this type of
movement at the first sign of resistance as damage
may result from over winding.
DATOMASTER MANUAL Setting the date
