Water Resistant
The water-resistance of IWC watches is shown in bar and not in metres. Metres, which are often used elsewhere in the watch industry to indicate water-resistance, cannot be equated with the dive depth because of the test procedures that are frequently used. By way of explanation: an IWC watch with an indicated water-resistance of 1 bar is protected against splashing water. With water-resistance of 3 bar, the watch can be worn when swimming or skiing, and at 6 bar it will have no problem with water sports or snorkelling. Diver’s watches with an indicated water-resistance of 12 to 20 bar are professional measuring instruments designed for scuba-diving. Special diver’s watches resistant to 100 bar or, as in the case of the Aquatimer Automatic 2000, 200 bar are suitable even for deep-sea diving. The recommended uses for IWC watches, depending on the degree of water-resistance, are established on this basis and on the basis of empirical data.
Remember that temperature fluctuations and external influences, for example due to solvents, cosmetics or dust, or caused by shocks, impacts or sudden movements, can fundamentally affect the water-resistance. Consequently, before engaging in activities that could be potentially damaging to your watch (team sports, high diving, etc.), you are advised to put it in a safe place. Please also bear in mind that not every strap or bracelet is suitable for use in or under water because of the materials used in its construction. Furthermore, with the exception of diver’s watches, the moving parts of the watch (crown, buttons, etc.) should not be operated under water. Before wearing the watch in or under water, you should also make sure that all moving parts are in the “off” position.
It should also be noted that the water-resistance of a watch is not a permanent characteristic. Seals and sealing systems in particular are subject to wear and tear and natural ageing. To care for your IWC watch, please read the operating instructions carefully. After use in or under water, your watch should be rinsed with clear, fresh and lukewarm water and then cleaned and dried. The water-resistance should be tested regularly, and at least annually, by an authorized IWC Official Agent.
Further instructions for care can be found in the corresponding operating instructions.
