WATER RESISTANCE
Please check the marking on the back of your watch case and refer to the following table to confirm the degree of water resistance of your watch and the preferable conditions of use. A watch’s water resistance is not permanently guaranteed. It is affected by the ageing of gaskets or deformation of watch parts due to accidental shock. To preserve a watch’s water resistance as long as possible, please follow the precautions below:
- Wipe off moisture, sweat or dirt with a soft dry cloth after removing it from the wrist in order to increase the durability of the case back, gaskets and band.
- After using a water resistant watch in ocean water, wash it in fresh water and dry it with a soft cloth.
- Do not wash a water resistant watch while the crown is pulled out.
- Do not operate the crown or press a button when the watch is wet.
- A periodic overhaul service is recommended to check the water resistance of the watch regularly to ensure it’s functionality.
