4. Operating Instructions
4.1 Chronograph Function
The chronograph function allows for precise timing. The watch features three sub-dials: a 60-second counter, a 60-minute counter, and a 24-hour display (often integrated with the moon phase or day/night indicator).
- Start/Stop: Press the upper push button to start the chronograph. Press it again to stop the timing.
- Reset: After stopping the chronograph, press the lower push button to reset all chronograph hands to their zero positions.

5. Care and Maintenance
- Water Resistance: This watch is 3ATM (30 meters/100 feet) water-resistant. It is suitable for daily use, such as hand washing or rain exposure. It is not recommended for showering, swimming, or diving. Ensure the crown is fully pushed in to maintain water resistance.
- Cleaning: Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel band, a slightly damp cloth can be used, followed by immediate drying.
- Avoid Chemicals: Do not expose the watch to harsh chemicals, solvents, or detergents, as these can damage the case, strap, or internal components.
- Temperature Extremes: Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, which can affect its accuracy and longevity.
- Magnetic Fields: Keep the watch away from strong magnetic fields, as they can interfere with the quartz movement.
