Operating Instructions
Using the Chronograph (Stopwatch)
Your Lorus RM335GX9 watch is equipped with a chronograph function, allowing you to measure elapsed time.
- Start: Press the upper pusher (A) to start the chronograph. The chronograph second hand will begin to move.
- Stop: Press the upper pusher (A) again to stop the chronograph. The elapsed time will be indicated by the chronograph hands.
- Reset: After stopping the chronograph, press the lower pusher (B) to reset all chronograph hands to their zero positions.
Note: The chronograph subdials typically measure seconds, minutes, and fractions of a second (e.g., 1/10th of a second). Refer to the watch face for specific subdial markings.
Maintenance
Water Resistance
Your watch has a water resistance rating of 100 meters (10 ATM). This means it is suitable for swimming and snorkeling, but not for diving. 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.
- Avoid exposing the watch to hot water, steam, or sudden temperature changes, as this can compromise the water seals.
Cleaning
To maintain the appearance of your watch:
- Wipe the case and crystal with a soft, dry cloth.
- For the leather strap, avoid prolonged exposure to water, direct sunlight, and harsh chemicals to prevent damage and discoloration.
Battery Information
This watch is powered by a quartz movement and uses a battery. The included battery has a typical lifespan of several years. When the battery needs replacement, it is recommended to have it done by a qualified watch technician to ensure proper sealing and function.
Troubleshooting
- Watch Not Running: Check if the crown is fully pushed in. If the watch still does not run, the battery may need replacement.
- Incorrect Time/Date: Refer to the 'Setting the Time' and 'Setting the Date' sections to re-adjust.
- Chronograph Hands Not Resetting to Zero: If the chronograph hands do not return to their 12 o'clock (zero) position after pressing the reset pusher, a calibration may be required. Consult a watch technician for assistance.
