small volume, a large number of components contribute to handling all the
functions. their mechanical action inevitably leads to a certain amount of
wear and tear, which may be controlled by maintenance consisting of renew-
ing the lubrication and replacing worn components. Like any precision

the movement of your chronometer is protected by a sophisticated case fitted
with water-resistance gaskets. Under the influence of certain external factors
such as perspiration, cosmetics, perfumes or dust, these gaskets progressively
deteriorate and must be periodically replaced, ideally every two years.
moreover, we recommend an annual water-resistance test, which takes only
a few minutes, performed by your authorized B
