Wristwatches & Corrosion

For most people wristwatches still are luxurious items of great value, may it monetary or be just subjective. Wristwatches are used under the most severe conditions such in deserts, on high altitudes, in water, while diving, in caves, on sailing ships, in space and even on the Moon. The usage itself may influence a watch’s life span. A wrong implementation of its functions may lead to damages.

Watches can be used in wet conditions but its push-buttons should not be operated underwater (only if otherwise specifically permitted). If a watch comes in contact with salt water it should be rinsed with warm fresh water. Salt water contains chlorides that can cause corrosion if not removed. The contact with chemicals or corrosive materials is key for corrosion to start. Some people own diving or outdoor watches that can be used in waters but taking a shower or bath is a different matter. Hot water may damage the water tight seals usually made of rubber. Likewise it is not recommended to place a watch in a bathroom while showering as the temperature difference can cause steam to drawn into the case of the watch what can also lead to corrosion. If water gets inside a watch a storage in a closed container may not be the best option. Instead it would be better to take the watch to a watchmaker for drying it out. Batteries used in watches, if not replaced timely, may leak causing corrosive internal damage.

The push-buttons and the crown of a watch use rubber seals that need regular lubricating and cleaning. To prevent moisture to get into the watch a regular maintenance is advisable. Watches used for scuba diving should be tested every year for water security by pressure testing. Metal surfaces of watches may corrode despite they are made out of superior metals such as stainless steel. Dust and dirt as well as the combination with salt or acids will cause corrosion with time even on a stainless steel strap of a watch.

Watches are used in the most severe environments. Corrosion occurs often because of negligence and an improper handling and cleaning. Some simple rules can help to reduce corrosion. Even with the best storage means and even using protecting films like Intercept corrosion may occur from the inside if watches are not handled with care.
