Care instructions

Care Instructions for Wristwatches

Care & Cleaning

  • Daily: Wipe 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 down the crown tightly beforehand!!!
  • Not waterproof: 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 allow to 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 by a master watchmaker every 5 years.

Storage & Handling

  • Store the watch separately, not directly with other jewelry (risk of scratching).
  • Take off mechanical watches when winding, do not leave the crown pulled out.

Jewellery Care – How to keep your jewellery beautiful:

  • Remove jewellery 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 jewellery.
