This watch has a manually wound spring drive.
You can wind the crown to wind the
mainspring to drive the watch.
The watch has two mainsprings, a first mainspring and a second mainspring. These two mainsprings can be simultaneously wound with one operation.
Guide for winding state of the mainspring
Manual winding:
Five full rotations of the crown will provide the power to run the watch for approximately ten hours.
Observe the power reserve indicator to check the level of the remaining power.
Power reserve indicator
Under a low-temperature condition (below 0 °C), always keep at
least one-sixth of the watch power shown by the power reserve indicator.
The
watch may stop.
How to manually wind the mainspring
-
Turn the crown at the normal position clockwise (12 o’clock direction) slowly.
-
Wind the mainspring until the power reserve indicator shows a fully wound state.
-
Make sure that the seconds hand is moving.

CAUTION
The crown cannot be turned further when the mainspring is fully wound to prevent overwinding of the mainspring. Do not try to forcefully turn the crown as this may damage the watch.
