A YEMA watch requires little maintenance. However, some precautions must be
taken to ensure the durability of your YEMA:
• Ensure that the crown is perfectly screwed down after winding up the movement and/or setting the
time and the date. Once the crown is fully screwed down against the case, your YEMA watch is
guaranteed waterproof.
• Avoid activities that may expose your watch movement to shocks.
• Never use chemicals to clean your YEMA watch. Use a microfibre cloth and wash the metal, rubber,
fabric bracelets and waterproof cases from time to time with a soft brush and soapy water. We
recommend that you do not use abrasive or corrosive products (solvents, detergents, perfume, etc.).
• Always rinse your watch with fresh water after it’s been exposed to salt water.
