Maintenance
Cleaning
Regular cleaning helps maintain the appearance of your watch. Use a soft, damp cloth to wipe the case and crystal. For leather straps, avoid excessive moisture and harsh chemicals. Allow the strap to air dry if it gets wet.
Battery Replacement
The watch is powered by a Lithium Metal battery. When the watch stops or the second hand begins to jump erratically, it's an indication that the battery needs replacement. Battery replacement should be performed by a qualified watch technician to ensure proper sealing and water resistance.
Water Resistance Care
Always ensure the crown is fully pushed in before exposing the watch to water. Do not operate the crown or pushers while the watch is wet or submerged, as this can compromise the water resistance seal.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If the watch still doesn't run, the battery may need replacement.
- Date Not Changing: Ensure the time is set correctly (AM/PM). The date typically changes around midnight. Avoid setting the date manually between 9 PM and 3 AM.
- Chronograph Hands Not Resetting to Zero: This may require a chronograph reset procedure. Consult a professional watch repair service if the issue persists after attempting a basic reset (pressing pusher B when stopped).
- Condensation Under Crystal: If condensation appears under the crystal, it indicates a loss of water resistance. Have the watch inspected and repaired by a professional immediately to prevent further damage.
