3.2 SPECIFIC PRECAUTIONS

PRECISION
The precision of a mechanical movement depends on several factors, but essen-
tially on the balance-spring/balance/escapement system, known as the regulating
organs.
Although CORUM movements are assembled with the utmost care, their precision
can be affected by the influence of gravity, magnetic fields, shocks and the fact that
the oil applied between many mobile elements can age. The rate regularity can be
measured by the variations between the different positions of the watch.
Your daily activities will have a direct influence on the precision of the movement. If
your watch is significantly fast or slow, please take it to a CORUM authorized dealer
who will make out the necessary adjustment.
A complete check of the watch is advised every 3 to 5 years depending on the
type of use made by the wearer, or even sooner if the time shown on the watch
becomes irregular.
Variation of quartz movement models is 2 to 3 minutes per year, subject to battery
life.
