4. Operating Instructions
4.1 Basic Timekeeping
Your watch displays hours, minutes, and seconds. The second hand moves continuously, indicating the current second.
4.2 Using the Chronograph
The chronograph function allows you to measure elapsed time independently of the main time display.
- Start: Press the upper pusher (button) to start the chronograph. The chronograph second hand will begin to move.
- Stop: Press the upper pusher again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Reset: With the chronograph stopped, press the lower pusher to reset all chronograph hands to their zero positions.
4.3 Water Resistance
This watch has a water resistance depth of 30 meters (3 ATM). This rating means the watch is suitable for everyday use and can withstand splashes or brief immersion in water, such as washing hands or light rain. It is not suitable for swimming, showering, or diving. Ensure the crown is fully pushed in before any contact with water.
5. Maintenance
5.1 Cleaning Your Watch
Wipe the watch case and metal band regularly with a soft, dry cloth to remove dirt and perspiration. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners or abrasive materials.
5.2 Battery Replacement
The watch is powered by a quartz movement with a battery. When the watch stops or the second hand begins to jump erratically (indicating a low battery), it is time for a battery replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
5.3 Storage
When not in use, store your watch in a cool, dry place away from direct sunlight and extreme temperatures. Avoid storing it near magnetic fields, which can affect the watch's accuracy.
6. Troubleshooting
- Watch not running: Check if the crown is fully pushed in. If it is, the battery may need replacement.
- Incorrect time: Reset the time as described in Section 3.1. If the time continues to be inaccurate, the watch may require servicing.
- Chronograph not resetting to zero: This may indicate a need for chronograph hand calibration, which should be performed by a professional.
- Condensation under crystal: This indicates a loss of water resistance. Avoid further contact with water and seek professional service immediately to prevent internal damage.
