Up to which depth are Longines watches water-resistant and when should I check the water-resistance?
All of our watches are crafted according to the norms of the Swiss watchmaking industry (NIHS). All modern Longines watches are water-resistant to 30, 50, 100 or 300 metres, depending on the model of watch. However, a hard knock might cause the watch to lose its water-resistance without you realising it. Therefore, if you plan to use your watch underwater, it is essential to have the water-resistance checked at least every 12 months. It is recommended to have the water-resistance checked and the seals replaced by an authorized repair centre every time the battery is replaced. Furthermore, we insist on the fact that, without any supplementary indication of pressure, our watches should not be used for scuba-diving.
