What are the precision tolerances for an Omega chronometer?

To earn the title of chronometer, the mechanical movement’s average daily variation in rate must be between -4/+6 seconds per day, or a precision of 99.99%, the highest precision attainable by a mechanical movement.

The precision of a mechanical movement depends on the individual habits of the wearer and can therefore vary. A qualified Omega watchmaker can adjust the precision of a watch to within the Omega tolerances, which are from -1 to +6 seconds per day.

What are the precision tolerances for other Omega mechanical watches?

The majority of watches that do not have a chronometer certificate have average precision tolerances of between -1/+11 seconds per day.

The precision of a mechanical movement depends on the individual habits of the wearer and can therefore vary. A qualified Omega watchmaker can adjust the precision of a watch to within the Omega tolerances.

What are the precision tolerances for Omega quartz watches?

All Omega quartz movements are produced in accordance with Omega’s highly renowned procedures and quality standards. Ambient temperature may affect the precision of quartz movements, which can lead to variations of between -0.5 and +0.7 seconds per day.

Official Omega statement

Yes. Omega watches are anti-magnetic in accordance with the definitions of the ISO 764 standard. This standard is based on the accidental passage of a watch in a magnetic field of 4,800A/m, i.e. 0.006 Tesla. As part of the ISO 764 test, the watch is placed in a magnetic field along 3 different axes, for one minute each time:

• Parallel to the plan-view of the watch, in the direction from 3 o’clock to 9 o’clock
• Then in the direction from 6 o’clock to 12 o’clock
• Then along an axis perpendicular to the plan-view of the watch.

In order to pass the test, a mechanical watch should not stop within the three periods indicated above. The effect of the residual magnetism should not exceed 30 seconds per day for a gents watch and 45 seconds per day for a ladies watch.

Yes. Omega watches are shock-resistant to 5000 g.
