– Setting the watch back by 12 hours during the afternoon between 2 p.m. and 10 p.m. will prevent
the calendar from advancing at midnight.
– Setting the watch back another 12 hours the following morning between 2 a.m. and 11 a.m. will
synchronize the date display with the local date.
Warning:
The watch must not be adjusted backwards between 10 p.m. and 2 a.m., as this would result in
a desynchronization that can only be rectified by a watchmaker.
As a result of the ever greater prevalence in recent years of very strong magnets made from rare-earth
alloys (e.g. neodymium-iron-boron) – these are found in objects such as loudspeakers and mobile
phones and fasteners on jewellery as well as handbags – mechanical watches are increasingly likely to
come into contact with such magnets and become magnetized. This can lead to the watch rate being
permanently affected, a problem that can only be resolved by a process of demagnetization carried
out by a specialist. We recommend that you keep your watch away from such magnets.
