Setup
Initial Charging
Your Lorus solar watch is powered by light. Before initial use, expose the watch dial to bright light (natural sunlight is ideal) for several hours to ensure it is sufficiently charged. Avoid placing the watch in direct sunlight for extended periods in extremely hot environments to prevent damage.
Setting the Time
- Pull the crown out to the second click position. The second hand will stop.
- Rotate the crown to set the hour and minute hands. Ensure the AM/PM is correctly set if your watch has a 24-hour sub-dial.
- Push the crown back to the normal position.
Setting the Date
- Pull the crown out to the first click position.
- Rotate the crown to set the date. Avoid setting the date between 9:00 PM and 1:00 AM, as this may interfere with the automatic date change mechanism.
- Push the crown back to the normal position.
Adjusting the Bracelet
The stainless-steel bracelet can be adjusted by removing or adding links. It is recommended to have this procedure performed by a qualified watch technician to prevent damage to the bracelet or watch.
Operating the Chronograph
The chronograph function allows for measuring elapsed time.
Chronograph Sub-dials:
- 60-minute sub-dial: Measures up to 60 minutes (typically at the 9 o'clock position).
- 24-hour sub-dial: Indicates the 24-hour time (typically at the 3 o'clock position).
- Small second hand: Operates as the running second hand for the main timekeeping (typically at the 6 o'clock position).
Basic Chronograph Operation:
- Start: Press button A (usually the top pusher) to start the chronograph. The chronograph second hand will begin moving.
- Stop: Press button A again to stop the chronograph. The elapsed time will be indicated by the chronograph second hand and minute sub-dial.
- Reset: Press button B (usually the bottom pusher) to reset the chronograph. All chronograph hands will return to their zero positions.
Maintenance
Charging Guidelines
To maintain optimal performance, ensure your watch receives regular exposure to light. If stored in darkness, the watch may stop. A fully charged watch can operate for several months in darkness.
Water Resistance
Your watch is water-resistant to 100 meters (10 BAR). This means it is suitable for swimming and snorkeling, but not for scuba diving. Do not operate the crown or pushers while the watch is wet or submerged.
Cleaning
Wipe the case and bracelet with a soft, dry cloth. For stainless steel, a slightly damp cloth can be used, followed by a dry cloth. Avoid using chemical cleaners.
Storage
When not in use for extended periods, store the watch in a well-lit area to keep it charged.
Troubleshooting
- Watch not running:
Ensure the watch is sufficiently charged by exposing it to bright light for several hours.
Check if the crown is pushed in completely.
- Date not changing:
Verify the time is set correctly, especially the AM/PM cycle.
Avoid setting the date between 9:00 PM and 1:00 AM.
- Chronograph hands not resetting to zero:
This may require a chronograph zero-position adjustment. Consult a qualified watch technician or refer to the full Lorus movement manual for specific adjustment procedures.
