LOUIS XVI watches are tested for water resistance up to 5 bar, which corresponds to the pressure of an assumed water column of 50 meters. This makes it suitable for everyday use, such as bathing, showering or washing hands. The water resistance of a watch can deteriorate over time, for example as a result of ageing seals or accidental knocks against one of the components responsible for water resistance, such as the crown, pushers or watch glass. We recommend that you have the water resistance of your watch checked once a year.
