INSTRUCTIONS
WINDING CROWN
The winding crown is used to manually wind the
watch (position 1) and to set the time (position 2).
Your watch is equipped with a screw-down crown
that must be completely unscrewed before you can
perform any adjustments.
WINDING
Your watch incorporates a self-winding movement.
The movements of your wrist set a centrifugal mass
in motion; this tensions the mainspring, which stores
the energy. When you take off your fully wound
watch, it will continue to run for at least 38 hours.
When it has stopped after depleting the power
reserve, it can be rewound by hand (about 10 clock-
wise turns of the crown).
