How to Set an Audemars Piguet Perpetual Calendar

Setting an Audemars Piguet Perpetual Calendar isn't just about adjusting a few dials; it's a meticulous process that requires precision and patience. This guide will unravel the complexities of setting this prestigious timepiece, ensuring you understand every step to maintain its accuracy and functionality.

Understanding the Perpetual Calendar Mechanism

Before diving into the setting process, it’s crucial to appreciate the sophistication behind a perpetual calendar. Unlike standard calendars, a perpetual calendar takes into account the varying lengths of months and leap years. This means that once set correctly, it will not require adjustment until the year 2100, barring any adjustments for daylight saving time or other minor deviations.

Preparing the Watch

1. Ensure the Watch is Wound: Begin by winding your watch fully. This ensures that the mechanism has enough power reserve to function accurately. Use the crown to wind the watch gently until you feel resistance.

2. Pull Out the Crown: The crown is the small knob on the side of the watch. For setting, you will need to pull it out to the second position. This position is generally used for setting the date and time.

3. Select the Correct Position: Depending on your model, there may be two or three positions on the crown. Pull it to the second position if you need to adjust the date and time.

Setting the Date and Time

1. Set the Time: Turn the crown to set the current time. Ensure you do this in a clockwise direction. If your watch has a 24-hour format, make sure to set AM/PM correctly to avoid any confusion.

2. Set the Day of the Week: Move the crown to adjust the day of the week. The perpetual calendar will automatically adjust for the length of each month, but you must set the correct starting point.

3. Set the Date: Next, adjust the date. Turn the crown to set the correct day of the month. The perpetual calendar should account for months with 30 and 31 days. Make sure the date corresponds accurately with the day of the week.

4. Set the Month: If your watch requires manual adjustment of the month, turn the crown to set the current month. Some models might automatically adjust the month, but always double-check.

5. Set the Year: Some models may have an additional setting for the year. If this is the case, turn the crown to adjust the year. This is critical for the leap year calculations.

Adjusting the Moon Phase

1. Locate the Moon Phase Indicator: On many perpetual calendars, there’s a moon phase indicator. This is usually a sub-dial or a separate display on the watch face.

2. Adjust the Moon Phase: To set the moon phase, you will need to align the display with the current moon phase. This might involve turning the crown or a separate screw-down adjustment. Consult your watch’s manual for the exact procedure.

Final Checks

1. Verify All Settings: Double-check all the settings you’ve made. Ensure that the date, time, day of the week, and month are all correct.

2. Push the Crown Back In: Once you are satisfied with all the settings, push the crown back to its original position. Make sure it is fully pressed to ensure the watch is sealed correctly.

3. Observe the Watch for Accuracy: Over the next few days, observe the watch to ensure it keeps accurate time and the calendar functions correctly. Minor adjustments might be necessary.

Maintenance Tips

1. Regular Winding: Even if not worn daily, the watch should be wound regularly to keep the movement lubricated.

2. Service Intervals: Schedule periodic servicing with an authorized dealer to ensure the perpetual calendar mechanism remains in optimal condition.

3. Avoid Magnetic Fields: Keep the watch away from strong magnetic fields, which can affect its accuracy.

4. Water Resistance: If your watch is water-resistant, avoid exposing it to excessive moisture and ensure the crown is properly secured.

Troubleshooting Common Issues

1. Date Change Not Aligning: If the date does not change as expected, check if the watch has a manual setting override or consult the manual for troubleshooting tips.

2. Moon Phase Display Incorrect: If the moon phase display is off, recalibrate it according to the manual or seek professional assistance.

3. Crown Difficulties: If the crown is hard to turn or feels stuck, do not force it. Seek professional service to avoid damaging the movement.

Conclusion

Setting an Audemars Piguet Perpetual Calendar requires careful attention to detail. By following the steps outlined above, you can ensure that your watch remains accurate and continues to showcase its intricate craftsmanship.
