3. Setup and Installation
The Sunon PE706 movement is designed for integration into watch cases. Professional watchmaking tools and expertise are recommended for installation.
3.1 Battery Installation
- Carefully remove the back cover of the watch case.
- Locate the battery compartment on the movement. Refer to the rear view image for guidance.
- Insert the correct type of watch battery (typically a button cell, specific type not provided, consult watch case specifications or existing battery) with the positive (+) side facing up.
- Secure the battery with its retaining clip, if present.
3.2 Hand and Dial Installation
- Ensure the movement is clean and free of dust.
- Carefully attach the main hour, minute, and second hands to their respective pinions.
- Install the sub-dial hands for the chronograph minute, small second, and any other indicators.
- Mount the dial onto the movement, aligning the dial feet with the movement's holes.
4. Operating Instructions
The PE706 movement features a crown for time and date adjustments, and typically two pushers for chronograph control.
4.1 Setting the Time
- Pull the crown out to the furthest position (Position 3). The second hand will stop.
- Rotate the crown to set the hour and minute hands to the desired time. Ensure the AM/PM (Sun & Moon) indicator is correctly aligned.
- Push the crown back into its normal operating position (Position 1). The second hand will resume movement.
4.2 Setting the Date
- Pull the crown out to the intermediate position (Position 2).
- Rotate the crown (usually clockwise or counter-clockwise, depending on the movement) to advance the date to the desired day.
- Push the crown back into its normal operating position (Position 1).
4.3 Sun & Moon / 24-Hour Indicator
The Sun & Moon indicator (or 24-hour sub-dial) typically operates in conjunction with the main hour hand, showing whether it is day or night. It cannot be set independently.
4.4 Chronograph Functions
The PE706 movement includes chronograph functionality with a center second hand and a minute counter sub-dial.
- Start: Press the upper pusher (typically at 2 o'clock) to start the chronograph. The center second hand will begin to move.
- Stop: Press the upper pusher again to stop the chronograph. The center second hand and minute counter will stop, displaying the elapsed time.
- Reset: With the chronograph stopped, press the lower pusher (typically at 4 o'clock) to reset all chronograph hands to their zero positions.
5. Maintenance
5.1 Battery Replacement
When the watch stops or the second hand begins to skip (indicating low battery), replace the battery promptly. Refer to section 3.1 for battery installation. Always use the correct battery type and dispose of old batteries responsibly.
5.2 Cleaning
Keep the movement free from dust and moisture. For internal cleaning, it is recommended to consult a professional watchmaker.
5.3 Storage
If storing the movement or watch for an extended period, consider removing the battery to prevent potential leakage and damage to the movement.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Watch stops or runs intermittently | Low or dead battery | Replace the battery (see Section 5.1) |
| Incorrect time display | Time not set correctly; hands misaligned | Reset the time (see Section 4.1); check for loose hands (professional repair recommended) |
| Date does not change or changes at wrong time | Date not set correctly; movement issue | Reset the date (see Section 4.2); if problem persists, consult a professional |
| Chronograph hands do not reset to zero | Chronograph not reset properly; internal misalignment | Ensure chronograph is stopped before resetting; if issue persists, professional adjustment may be needed |
| Inaccurate timekeeping | Weak battery; exposure to strong magnetic fields; internal damage | Replace battery; keep away from magnets; professional inspection for damage |
7. User Tips
- When setting the date, avoid adjusting it between 9 PM and 3 AM, as this can interfere with the automatic date change mechanism and potentially damage the movement.
- Always ensure the crown is fully pushed in after setting the time or date to maintain water resistance (if applicable to your watch case) and prevent dust ingress.
- If the chronograph hands do not align perfectly to zero after resetting, some watch cases allow for micro-adjustment of the hands via specific crown/pusher combinations. Consult your watch case manual or a professional.
