Clean your watch regularly with a soft cloth and lukewarm soapy water. After swimming with your watch in salt water, rinse it off with fresh water and allow it to dry completely. Avoid exposing the watch to extreme temperature or humidity fluctuations, direct sunlight, or strong magnetic fields. For watches with leather watchstraps, high-quality natural leather is used. To protect your watchstrap, we recommend that you avoid exposing it to water or moisture, skin cream or cosmetics, or prolonged direct sunlight as much as possible. Important: before you clean your watch, make sure that the crown is screwed in all the way to the case. We recommend that you have your watch inspected regularly to verify that it is water-resistant. This inspection should be conducted every year and whenever the watch has sustained a blow or shock. Because oils and greases are subject to aging, you should have the movement cleaned and inspected every 4 years to keep your watch in top working order.
