RETROGRADE DATE, DAY, POWER RESERVE
FUNCTIONS
Retrograde date
The date hand moves backward after having reached its final mark and begin a new cycle.
Power reserve indicator
For models with a power reserve indicator, the hand (L) indicates, on a scale which may vary per model,
the amount of time remaining until the watch must be wound again. When the watch is entirely wound,
the indicator sits at its maximum position.
WINDING
Self-winding mechanical watch
An automatic or self-winding mechanical watch has a sophisticated mechanism which winds it up
automatically thanks to the movements of the wearer's wrist.
When fully wound, your automatic watch has a power reserve of approximately 42 hours. The
accumulated power reserve enables the watch to run throughout the night and still possess a comfortable
margin of autonomy.
Nevertheless, if you have not worn your watch for several days, it will stop or will have insufficient
power reserve to ensure optimal accuracy, which is reached when the watch is fully wound. In this case,
before using it again, we suggest you wind it manually with about 20 clockwise turns of the crown to
ensure that it will operate perfectly in all conditions. After wearing your watch for several hours,
depending on your activity level, the watch will be perfectly wound.
Note:
- The efficiency of the self-winding process is directly linked to the motion of the wearer's wrist. In case
of insufficient movements, the watch may stop even while being worn. In this case, we recommend to
preventively wind the watch manually with about 20 clockwise turns of the crown.
Also, the watchband must be correctly fitted to the wearer's wrist: if the watchband is too loose, the
watch may not wind itself correctly.
- The watch should be removed from your wrist before winding it. This ensures the crown stem remains
completely straight during winding and avoids the risk of damaging the crown or the movement.
- Do not deliberately shake a self-winding watch in order to wind it. This is ineffective and could damage
the movement.
- Even if your watch is not worn for several months we advise you to regularly wind it manually. This
will prevent the oils from either congealing or flowing over the shafts of the movement.
