BAUMATIC – HOUR, MINUTE, CENTRE SECONDS,
FUNCTION
Perpetual calendar
A perpetual calendar is a horological complication that takes account of leap years and ensures automatic
date correction whatever the number of days in a month (28, 29, 30 or 31).
Kindly note that it requires one correction per century, since century years are not leap years. This means
that a current perpetual calendar model will need no adjustment until 2100.
This complication is generally combined with "Complete calendar" and "Moon-phase complications".
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 120 hours (5 days). The
accumulated power reserve enables the watch to be taken off and worn again after a long weekend or
week.
Nevertheless, if you have not worn your watch for several days, it will stop. In this case, before using it
again, we suggest you wind it manually with about 50 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 50 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.
