3. Setup
3.1 Initial Winding
Your Frederique Constant watch is equipped with a Swiss automatic movement. This means it is powered by the natural motion of your arm. If the watch has stopped or has not been worn for an extended period, it requires initial winding:
- Ensure the crown is in the fully pushed-in, screwed-down position.
- Unscrew the crown by turning it counter-clockwise until it springs out slightly.
- In this first position (Position 0), wind the watch manually by turning the crown clockwise approximately 30-40 times. This will build up a power reserve.
- After winding, gently push the crown back in and screw it clockwise to ensure water resistance.
3.2 Setting Time, Date, and Moon Phase
To set the various functions of your watch:

- Unscrew the Crown: Turn the crown counter-clockwise until it is released from the case.
- Setting the Date: Pull the crown out to the first click (Position 1). Turn the crown clockwise to adjust the date hand. Adjust the date to the day before the current date.
- Setting the Moon Phase: While in Position 1, turn the crown counter-clockwise to adjust the moon phase indicator. Align it to the current moon phase.
- Setting the Time: Pull the crown out to the second click (Position 2). The second hand will stop. Turn the crown to move the hour and minute hands clockwise until the date changes to the current date. Continue turning to set the correct time, ensuring you distinguish between AM and PM (e.g., if setting for PM, pass 12 o'clock once).
- Synchronizing: Once the time is set, push the crown back to Position 0 and screw it clockwise firmly against the case to ensure water resistance.
4. Operating
Once set, your automatic watch will continue to run as long as it is worn regularly. If not worn, it is recommended to wind it manually every two weeks to maintain its power reserve.
- Daily Wear: The movement of your arm will keep the watch wound.
- Crown Positions:
- Position 0 (Screwed-down): Normal operating position, water-resistant.
- Position 0 (Unscrewed): Manual winding.
- Position 1 (First click): Quick adjustment of date and moon phase.
- Position 2 (Second click): Time setting (stops second hand).
5. Maintenance
5.1 Cleaning
To maintain the appearance of your watch:
- Wipe the case and sapphire crystal with a soft, dry, lint-free cloth.
- For stubborn dirt, a slightly damp cloth can be used, but ensure the crown is fully screwed down. Dry immediately.
- Avoid using harsh chemicals or abrasive materials.
5.2 Water Resistance
Your watch is water-resistant to 10 ATM (100 meters / 330 feet). This rating makes it suitable for swimming and snorkeling, but not for diving. Always ensure the crown is fully screwed down before exposing the watch to water. Do not operate the crown or pushers while the watch is wet or submerged.
5.3 Strap Care
The black leather strap requires care to prolong its life:
- Avoid prolonged exposure to direct sunlight, extreme temperatures, and moisture.
- If the strap gets wet, dry it gently with a soft cloth and allow it to air dry completely away from direct heat.
- Leather straps are subject to wear and tear and may need replacement over time.
6. Troubleshooting
If you encounter issues with your watch, consider the following common solutions:
- Watch has stopped: The watch may have run out of power reserve. Manually wind the watch as described in Section 3.1.
- Date not changing at midnight: Ensure the time is set correctly for AM/PM. If the date changes at noon, you have set the time 12 hours off. Adjust the time accordingly.
- Condensation under crystal: This may indicate a loss of water resistance. Avoid further exposure to water and seek professional service immediately.
- Inaccurate timekeeping: Automatic watches can vary slightly in accuracy. If the deviation is significant, the watch may require regulation by a qualified watchmaker.
For issues not resolved by these steps, please contact an authorized Frederique Constant service center.
