When you receive your mechanical watch: A. Setting the time Pull the crown away from the base of the watch and turn the crown clockwise until you reach the correct time. B. Winding the clock Push the crown back into its original position on the watch and wind it by rotating it clockwise 20-30 times. The power will be full (overwinding will break the mainspring at the end). Do this once a day (before bed). Otherwise, the clock will stop. If the crown feels tight, please stop winding the watch.
