Check your watch manual: the movement must support hand-winding. Work with the watch off your wrist.
Unscrew a screw-down crown first. In the manual's winding position, turn clockwise gently. Never force it.
Follow the manual's stopping guidance. Return the crown and screw it back down gently if fitted.
Avoid date changes during the manual's warning window. Check your watch manual for the specific hours.
A winder is optional. Store your watch dry and separate from loose accessories between wears.
Read the full winding guide for crown handling, restarting and the manual checks that matter.
