Maintenance
The description above should have proved, that your new pendulum clock is a precision
chronometer of highest quality.
As every other instrument of this kind Cal. 2011 also requires careful handling and a certain
degree of maintenance. We therefore advise you never to keep the clock case open over
a long period of time, in order to prevent dust from depositing on the clockwork.
After 10 years the latest you should entrust your pendulum clock to a competent clockmaker's
workshop in order to have the clockwork cleaned and oiled anew. In the case of a pendulum
clock, which keeps precious time over many years , 24 hours a day, exactly to the second, this
should be self-evident. It will then untiringly do good service over decades and will be passed
on with pride from generation to generation as a precious chronometer.
