All modern Longines watches are crafted according to the norms of the Swiss watchmaking industry (NIHS) and are water-resistant to 30, 50, 100 or 300 metres, depending on the model of watch. At the time of purchase, the water-resistance of your watch is symbolized by one of the following icons:
Please note that the water-resistance of a watch is not a permanent characteristic. It may notably be affected by the ageing of gaskets or by an accidental shock to the crown.
The water-resistance should be tested regularly, and at least once a year, by a Longines authorized Service Center.
Furthermore, we insist on the fact that, without any supplementary indication of pressure, our watches should not be used for scuba-diving.
