Winding the mainspring
This is an automatic mechanical watch powered by a spring.
When wearing the watch, your arm's movement rotates the oscillating weight to
wind the mainspring automatically.
• When your arm's movement is small and/or a few, winding will become
insufficient. We recommend to wear the watch as long as possible or wind the
mainspring manually in such cases.
• When not worn, the mainspring will run out in about 2 or 3 days and the watch
will stop.
• Once the mainspring is wound fully, the watch will run for about 50 hours.
Winding the mainspring manually

Hold the crown with your thumb and index finger and rotate it clockwise
slowly.
• When the watch is stopped, turning the crown about 42 times will wind the
mainspring fully.
• Rotating the crown further after the mainspring was wound fully does not damage
the mainspring.
• Rubbing down the crown from the back side of the watch can also rotate it.
