Accuracy and precautions for use
MANUALLY-WOUND OR AUTOMATIC
MECHANICAL WATCHES
The accuracy of watch models with mechanical
movements is determined by the balance
wheel. This oscillates at a rate of 28,800
vibrations per hour. Despite all the care that the
master watchmakers of the Jaeger-LeCoultre
Manufacture have lavished on building and
assembling your watch, its accuracy is subject
to the influence of gravity, magnetic fields,
accidental impacts, and the ageing of the oils.
The accuracy of a watch is measured by its
regularity of rate in various positions.
