How do I set the time on Cal. 730 watches with a screw-down crown?
- Turn the crown counterclockwise until the thread loosens (position 1, winding position).
- The crown is now in position 1 and can be operated (winding position).
- Pull the crown to position 3 to set the time correctly (second hand stops).
- After operation, the crown must be screwed back in by pressing it against the case and turning it clockwise until it locks.
