Water resistance

All our watches are thoroughly tested to comply with the specified water resistance (WR) rating for that watch.

  • For starters, there are very specific tolerances required to meet a particular WR rating. We design our cases in accordance with these rules. For example, the case back on a 300m WR watch has to be thicker than a 100m WR case back.
  • Once the cases are assembled, they will be tested in real water to check for leaks.
  • After full assembly, the watch is then tested in a vacuum

Important to note though, even if a watch is rated to 100m, does not mean that it should be used for scuba diving application. The standards of water resistance do not take into account the changes in seawater temperature, ageing or seals and rapid changes in water pressure. As a guide, the following activities apply for the relevant WR rating.

50m WR  – you could get away with submerging it in water for a short while, but little more than that.

100m WR – good for swimming, and snorkelling.

200/300m WR – suitable for recreational scuba diving

500m WR or more – rated for more extreme diving

Avoid over tightening the crown of your watch. This can cause wear on the seals, and over time they will perish. We recommend having the seals of your watch checked once every five years, especially if you are exposing it to moisture on a regular basis.

Note: we do not recommend wearing our watches in the shower or bath. Exposure to soaps and steam can accelerate the penetration of water into the seals of your watch, and potentially damage the movement.
