resistance tested once a year by an approved OMEGA service centre

What are the intervals between services?
Like any precision instrument, a watch requires regular servicing to ensure it operates
perfectly We cannot specify the frequency of this operation, since it is entirely dependent
on the model, climate and care that each owner takes with their watch As a general rule,
a watch should be serviced every 5 to 8 years, according to the conditions under which it
is used
