"
seal engraved on the back of the watch certi-
fies that each of the models from our collection
has successfully undergone all of the qualifica-
tion tests, and that your watch has successful-
ly undergone all of the production tests. These
ensure regularity of rate, resistance to varia-
tions in temperature and atmospheric pressure,
ability to withstand shocks and magnetic fields,
as well as water resistance.
