Winding the mainspring
Automatic winding function
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 60 hours.
