Operating Instructions
Chronograph Function (Stopwatch)
The chronograph allows for precise timing of events.
- **Start/Stop:** Press the top pusher (labeled "Start/Stop" in the diagram) to start the chronograph. Press it again to stop.
- **Reset:** While the chronograph is stopped, press the bottom pusher (labeled "Reset" in the diagram) to reset all chronograph hands to zero.
Subdials
- **24 Hours Display:** Indicates the time in a 24-hour format, useful for distinguishing AM/PM.
- **Minute Subdial:** Measures elapsed minutes during chronograph operation.
- **Second Subdial:** Measures elapsed seconds during chronograph operation.
Luminous Hands
The watch features luminous hands and markers that absorb light and glow in the dark, allowing for easy readability in low-light conditions.
Maintenance
- **Cleaning:** Wipe the watch regularly with a soft, dry cloth to remove dust and smudges. For the stainless steel bracelet, a slightly damp cloth can be used, followed by drying.
- **Water Resistance:** The watch is 5ATM (50 meters) water resistant, suitable for daily use like handwashing or rain. It is NOT suitable for swimming, diving, or hot showers/saunas, as steam can penetrate the seals. Ensure the crown is fully pushed in before any contact with water.
- **Avoid Chemicals:** Keep the watch away from harsh chemicals, solvents, and detergents, which can damage the case, strap, or seals.
- **Temperature Extremes:** Avoid exposing the watch to extreme temperatures (hot or cold) or sudden temperature changes, as this can affect the movement and battery life.
- **Magnetic Fields:** While the watch is shock-resistant and anti-magnetic, prolonged exposure to strong magnetic fields (e.g., speakers, magnets) should be avoided as it can affect timekeeping accuracy.
- **Battery Replacement:** The watch uses a quartz movement with a battery. When the watch stops or the second hand starts skipping, it's time for a battery replacement. It is recommended to have this done by a professional watchmaker to ensure proper sealing and water resistance.
