OMEGA
watches with a chronometer-certified movement
A chronometer is a high-precision watch whose movement has been
individually tested, for 15 days in 5 positions and at 3 temperatures,
by a neutral official body (COSC) in accordance with the ISO 3159
(NIHS 95-11) Standard. Each chronometer is unique, and identified by
a number engraved on its movement.

Master Chronometer
OMEGA
certified watches
In addition to the COSC movement certification, Master Chronometer
watches are individually tested at
OMEGA
for 10 days before they
are delivered to the end customer. Test trials, based on a simulation
of wear of the finished watch, aim to ensure the precision, resis-
tance to magnetic fields (1.5 tesla / 15,000 gauss), power reserve
and water-resistance of Master Chronometer watches. The process,
measurement equipment, and results obtained for each watch are
certified by METAS.

Your
OMEGA
watch is designed to resist a magnetic field of
15,000 gauss. This is an intensity higher than any to which it will be
exposed in everyday use (for example, the magnet in a handbag clasp
may attain 2,000 gauss). Not only will your watch not stop in the pre-
sence of a magnetic field, it will not even suffer any loss of accuracy
after being exposed to such a field.
