Water resistance is a crucial feature for any watch, whether it’s intended for everyday use or specific aquatic activities. A waterproof watch protects the internal mechanism from water, dust, and other contaminants. In this article, we’ll explore how to keep your watch water-resistant, with essential tips and precautions to consider.
Understanding Waterproofing Levels
Before discussing the precautions to take, it is important to understand the different levels of waterproofing indicated by manufacturers:
Water Resistant: Indicates minimum protection against splashes.
3 ATM / 30 meters: Rain and splash resistant.
5 ATM / 50 meters: Can be used for showering or light swimming.
10 ATM / 100 meters: Suitable for swimming and snorkeling.
20 ATM / 200 meters and more: Suitable for professional scuba diving.
Tips for Maintaining the Water Resistance of Your Watch
Have Your Watch Checked Regularly
It is advisable to have the water resistance of your watch checked at least once a year by a professional watchmaker. The seals can deteriorate over time and must be replaced periodically.
Avoid diving or water sports
Sudden changes in pressure can deform components and compromise the effectiveness of seals, it can also generate pressure greater than the watch can withstand! Indeed, a dive can subject the watch to pressure of up to 20ATM!
Avoid Hot Water and Chemicals
Exposure to hot water, soap, chemicals or perfumes may damage the seals. It is recommended to remove your watch before showering or going into a sauna.
Make sure the crown is screwed down securely
The crown (the setting button) must be screwed in or pushed in securely before immersing in water. A loose crown is one of the main causes of water entering the watch.
Avoid Thermal Shock
Sudden changes in temperature can cause watch components to contract and expand, compromising water resistance. Avoid moving quickly from a very hot environment to a very cold environment, and vice versa.
Clean Your Watch After Salt Water Immersion
If you wear your watch in salt water, rinse it with fresh water after each immersion. Salt can corrode gaskets and other metal components, reducing water resistance.
Avoid Underwater Handling 
Do not operate the buttons or crown of your watch underwater. This may allow water to seep into the case, even if the watch is rated as water-resistant.
Do not hold the watch directly under running water.
The pressure of tap water is sufficient to reduce the waterproof performance of a waterproof watch designed for everyday use.
Signs of a Loss of Sealing
Condensation under the glass
If you notice condensation inside your watch, it means that water has gotten in.
Fog or droplets inside
Water droplets or fog on the dial are clear indicators of sealing problems.
Irregular operation
If your watch begins to function erratically after exposure to water, it may have suffered internal damage due to moisture.
Only use watches designed for diving.
Ensuring the water resistance of your watch is essential to protect its internal mechanism and extend its life. By following these tips and taking the necessary precautions, you can fully enjoy your watch, even in aquatic environments. Don't forget to have your watch checked regularly by a professional to ensure its proper functioning and water resistance.
By applying these measures, you can ensure that your watch remains in perfect condition, no matter what conditions it is exposed to.
