Waterproof Smart Watches

Water Resistance Guide

There is often confusion on what the stated water resistance of watches actually mean. Does a watch with '50 metres' as the water resistance mean you can dive with it as deep as 50 metres? No, you cannot - as it actually refers to static pressure and not the actual depth of water it can be used in. This is a common misconception.

50 metres refers to the pressure experienced if it was static at a depth of 50 metres. When the watch moves the pressure rises well above a static pressure of 50 metres. 50 metres of static water pressure is easily achieved even in shallow depths. Consequently, a 50 metres watch should not be used for diving, however it can be immersed in water.

Please refer to the water resistancy guidelines below of accordingly rated watches.

Water resistant: Splash proof only - it can withstand slight splashes and rain, but is NOT to be immersed in water.

30 metres/ 3 ATM: Splash proof and waterproof in small amounts of water

50 metres/ 5 ATM: Can be submerged in water. Suitable for swimming, but not guaranteed to be resistant to jumping into the pool.

100 metres / 10 ATM: Suitable for swimming and shallow diving

200 metres / 20 ATM: Suitable for diving - not deep sea.

If you have the battery of your watch changed, you should be sure to have it resealed and pressure tested by the jeweller to ensure that it is still water resistant to the stated depth.

Please note that continued exposure to water may affect the lifespan of a leather strap, and proper care should be taken as per the manufacturer's guidelines.
