Water Resistance Guidelines

Your watch is rated for 50-meter (5 ATM) water resistance. This means it is suitable for:

  • Daily use, such as hand washing or splashes.
  • Short periods of recreational swimming in shallow water.

Important Precautions:

  • Do not operate the crown or push buttons while the watch is wet or submerged.
  • Avoid prolonged exposure to water, hot water, or steam (e.g., showers, saunas).
  • Water resistance is not a permanent condition and may decrease over time due to wear and tear.

Maintenance

Battery Replacement

The watch is powered by a single product-specific battery. When the watch stops or the hands move erratically, it indicates that the battery needs replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.

Cleaning Your Watch

To maintain the appearance of your watch:

  • Wipe the watch case and band with a soft, dry cloth regularly.
  • For metal bands, a soft brush and mild soapy water can be used, followed by thorough rinsing and drying. Ensure the crown is pushed in before cleaning with water.
  • Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish.
