The crown has two positions:
1. Winding position
2. Time-setting position
Starting the watch
Crown in position 1 . This position
allows you to rewind the movement.
To start the watch, wind it fully by
turning the crown upwards (
▲ ▲
) until
resistance is felt (DO NOT FORCE THE
CROWN).
After each rewinding, we recommend
a half turn of the crown downwards
(
▼ ▼
) to release the crown wheel and
ensure optimal running.
This watch has a manually rewound
movement with a power reserve of
40 hours. However, to ensure optimal
working we recommend rewinding
every day at a regular time.
Setting the time
Pull the crown out to position 2 . Turn
the crown downwards (
▼ ▼
) to move
the hands to the desired time. To set
your watch precisely, end by turning
the crown upwards (
▲ ▲
). Then push
the crown back to position 1 . After
this operation, rotate the crown down-
wards (
▼ ▼
) to ensure it turns freely.
To set the watch precisely, carry out
the rewinding before setting the time.
