- If moisture is detected inside the watch, have it inspected immediately to prevent corrosion.
- Avoid exposure to extreme temperatures.
- Do not subject the watch to strong impacts or drops.
- Do not overtighten the watch strap; a finger should fit between the strap and your wrist.
- Clean the watch and strap with a dry, soft cloth or a slightly damp cloth with mild detergent. Avoid solvents like benzine, alcohol, or spray cleaners.
- Gold-plated surfaces can be maintained by regular wiping with a soft, damp cloth. Discoloration can be removed with cleaning agents.
- Always store the watch in a dry place.
- Avoid contact with gasoline, cleaning solvents, aerosol sprays, adhesives, paint, and other chemicals, as these can damage gaskets, the case, and the finish.
- Some models have silk-screened designs on the strap; clean these carefully to avoid damage.
- For water-resistant models with leather straps, do not wear them while swimming or engaging in water activities.
