Setup
Winding the Automatic Movement
Your Frederique Constant watch is equipped with an automatic self-winding mechanical movement. This means the watch is powered by the natural motion of your wrist. When fully wound, the watch has a power reserve of approximately 40 hours.
- Initial Winding: If the watch has stopped or has not been worn for an extended period, manually wind it by rotating the crown clockwise approximately 20-30 times while it is in its normal (pushed-in) position. This will provide sufficient power to start the movement.
- Daily Operation: Once started, wearing the watch for at least 8-10 hours a day will keep it sufficiently wound. If worn less frequently, occasional manual winding may be necessary.
Setting Time and Date
To set the time and date on your watch:
- Setting the Date: Gently pull the crown out to the first position. Rotate the crown either clockwise or counter-clockwise (depending on the movement) to adjust the date. Avoid setting the date between 9 PM and 3 AM, as this can damage the movement.
- Setting the Time: Pull the crown out to the second (outermost) position. The second hand will stop. Rotate the crown to set the hour and minute hands. To ensure accurate time setting, synchronize with a reliable time source. Push the crown back into the normal position to restart the second hand.
- Secure the Crown: Always ensure the crown is fully pushed back into its normal position after setting to maintain water resistance.
Operating
Wearing the Watch
Ensure the watch strap is comfortably fitted to your wrist, allowing for slight movement without being too loose or too tight. A proper fit ensures the automatic movement can function effectively.
Water Resistance
Your watch is water resistant to 50 meters (165 feet). This rating means it is suitable for short periods of recreational swimming. It is not suitable for diving, snorkeling, or prolonged water immersion. Always ensure the crown is fully pushed in before any contact with water. Do not operate the crown or pushers while the watch is wet or submerged.
Maintenance
Cleaning and Care
- Cleaning: Use a soft, dry cloth to wipe the case and crystal regularly. For the leather strap, avoid excessive moisture and harsh chemicals.
- Avoid Extremes: Protect your watch from extreme temperatures (hot or cold), strong magnetic fields, and severe shocks.
- Chemicals: Avoid contact with solvents, detergents, perfumes, and cosmetic products, as these can damage the case, strap, or gaskets.
Professional Servicing
For optimal performance and longevity, it is recommended to have your mechanical watch serviced by an authorized Frederique Constant service center every 3-5 years. Regular servicing includes cleaning, lubrication, and adjustment of the movement, as well as checking and replacing gaskets to maintain water resistance.
Troubleshooting
Watch Not Running
- Ensure the watch has been manually wound (20-30 turns of the crown) if it has stopped.
- Confirm the watch is being worn regularly for sufficient periods to allow the automatic movement to self-wind.
Inaccurate Time
- Automatic movements may have slight variations in daily accuracy. If the watch is consistently gaining or losing a significant amount of time (e.g., more than +/- 20 seconds per day), it may require adjustment.
- Exposure to strong magnetic fields can affect accuracy. If suspected, a professional watchmaker can demagnetize the watch.
- If accuracy issues persist, consult an authorized service center.
