Care instructions

Care Instructions for Wristwatches

Care & Cleaning

  • Daily: Wipe the case and strap with a soft, dry cloth to remove dirt and sweat.
  • Water-resistant watches: Clean with mild soapy water and a soft brush, rinse, and dry thoroughly.
    Important: Screw the crown down tightly beforehand!!!
  • Not water-resistant: Clean only dry or slightly damp, do not use water or cleaning agents.
  • Avoid: Aggressive agents, perfume, cosmetics, and heat.
  • Leather straps: Do not soak, clean only slightly damp, and let dry away from heat.
  • Water resistance: Do not wear when showering or bathing, have it checked annually.
  • Battery (Quartz): Have a dead battery replaced immediately.
  • Mechanical watches: Service every 5 years by a master watchmaker.

Storage & Handling

  • Store the watch separately, not directly with other jewelry (risk of scratches).
  • When winding mechanical watches, take them off; do not leave the crown pulled out.

Jewelry Care – How to Keep Your Jewelry Beautiful:

  • Remove jewelry before showering, bathing, and sports.
  • Avoid direct sunlight – wood, leather & co. can fade.
  • Hands off – constant touching leaves grease and dirt.
  • No aggressive cleaning agents such as chlorine, salt water, or disinfectants.
  • Apply cosmetics and perfume first, then put on jewelry.
