Precision tolerances
3
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.
Other OMEGA mechanical watches
The majority of watches that do not have a chronometer certifi-
cate have average precision tolerances of between -1 and +11
seconds per day.

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.
Quartz watches with thermocompensation
(calibre 1680)
This movement is fitted with an electronic module that compensates
for the effects of temperature on the movement’s precision. These
watches are accurate to /- 0.055 seconds per day.
The precision of a mechanical watch cannot be compared to that
of a quartz watch, given that the two are based on different tech-
nologies.
