CLUSE watches are 3ATM water resistant. This means that the watch is suitable for everyday use (for example, it can withstand a few accidental drops of water while washing your hands). However, the watch is not suitable for showering, swimming and other water related activities. Please note CLUSE watches can also be influenced by water vapour and condensation caused by warm environments or conditions. Damages caused by water inside the watch are not covered by the warranty.
