• 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.
