Water Resistance

With watches, we are not talking about water water proofness, but about water resistance, since watches are never completely waterproof. Virtually nothing is as harmful to your watch as water, because water causes rust and rust can have disastrous consequences for the timepiece in a short time.

Water resistance means how resistant the watch is to water, or to the pressure exerted by a certain amount of water. The degree to which a watch is water resistant is indicated on the back of the case or on the dial. The unit (ATM, Bar, M or FT) refers to the static pressure that the watch can withstand. Static pressure can be seen as the pressure on a stationary watch in still water. These numbers indicate how much pressure the watch can withstand. It does NOT refer to depth, although this is a common misconception. It is important to remember that water resistance is measured in a static or motionless state under ideal conditions. It is not taken into account that the pressure increases with the speed (movement). When you swim, you add pressure by simply moving the watch in water. Watches are made water-resistant with gaskets or rubber rings that are used to waterproof openings around the crown, buttons or back cover.

Gaskets or rubber rings can harden and crack over time. What also has consequences are large temperature differences. If a watch is warmed up during sunbathing and the wearer takes a dip after this, the watch will receive a huge “blow” due to the relatively large temperature difference. If the watch case is not resistant to such conditions, the watch may leak and fill with water. The glass and metal of the watch can expand with such a sharp fluctuation in temperature. It is a minor deformation that cannot be seen with the eye, but it does affect the watertightness of the gasket and can cause leakage.


Is your watch protected against water? These are the general guidelines:


3 ATM / 3 bar / 30 meters:                                                                                                                                                                             The watch is protected against splash water. You can wear it while washing your hands, because it can get wet for a short time (for example by rain). The watch is not suitable for showering, swimming or diving!


5 ATM / 5 bar / 50 meters:                                                                                                                                                                       Suitable for getting completely wet, but do not shower with it because of large temperature differences and do not swim with this watch.


10 ATM / 10 bar / 100 meters:                                                                                                                                                                 Suitable for swimming and snorkeling. Not suitable for diving.


20 ATM / 20 bar / 200 meters:                                                                                                                                                                 Suitable for swimming and diving in seas or lakes. Not suitable for deep sea diving.


100 ATM / 100 bar / 1000 meters:                                                                                                                                                          Suitable for scuba diving.


Condensation                                                                                                                                                                                     Condensation can form in any watch, often caused by large and sudden temperature differences, even in the best diver's watches. Consider, for example, a dip in cold water after sunbathing or cycling in a heavy rain shower. These are just a few examples.

Condensation may form under the glass in the event of sudden temperature differences, as described above. Then there is not necessarily any moisture penetrated into the cupboard. Unless thick drops are visible under the glass, moisture has probably penetrated and it is advisable to have the watch case / watch dry as soon as possible.

It is not recommended to lie in the sun with your watch, inside the case a very high temperature can occur which is harmful to the gaskets and your watch. When your watch is exposed to too high temperature differences, your watch can lose its water resistance completely and even fill up with water.

Moisture in the case can cause rust and eventually (irreparable) damage to the timepiece. Salt water is even more harmful in this case. Often damage can no longer be repaired.

Damage to the timepiece is not the only reason to be careful with water. Also consider the (leather) strap of the watch and the PVD coating around the case or strap. Salt seawater is very harmful, therefore avoid any contact with it.


Liability                                                                                                                                                                                                             Our urgent advice is to not - never go swimming with your watch. Exclusive24-7 is not liable for any water damage. The general guidelines stated above are general guidelines. Exclusive24-7 gives no warranty on the guidelines. The same applies to showering and wearing your watch in a sauna or steam bath. Hot water (also from the tap), steam and heat from a hair dryer, for example, may deform and damage the watch's gaskets and cause damage to the watch. The crowns and push buttons may just not be closed properly during wearing or due to certain actions.


Chemicals                                                                                                                                                                                                Chemicals such as oil, chlorine, perfume, alcohol, hairspray, cleaning agents, sunscreen, etc. can also damage the gaskets of your watch and not only that, for example, the PVD coating on your watch that can be damaged. To keep your watch in top condition, we recommend avoiding this kind of contact.

Unfortunately, we cannot guarantee any damage caused by water unless the watch clearly has a factory defect.

We hope that we have given you more background information about watertightness, but we can imagine that you have any questions. Do not hesitate to contact our customer service, our employees are happy to advise you.
