How to Change the Date on a Breitling Navitimer Watch

Changing the date on a Breitling Navitimer watch requires careful attention to detail to ensure accuracy and prevent damage to the watch's movement. Here is a comprehensive guide on how to do it properly:

1. Prepare Your Watch:

• Check the Time: Before adjusting the date, make sure your watch is showing the correct time. If not, set the time to the correct hour and minute.
• Avoid the Danger Zone: Avoid setting the date between 8 PM and 4 AM, as the date-change mechanism is engaged during this time, and manual adjustment can cause damage.

2. Pull Out the Crown:

• Locate the Crown: The crown is the small knob on the side of the watch case.
• Pull Out the Crown: Gently pull the crown out to the second position. This is typically the farthest position from the watch case and is used for changing the date.

3. Adjust the Date:

• Turn the Crown: Rotate the crown clockwise or counterclockwise to change the date. The exact direction can vary depending on the model, so if unsure, consult the user manual for your specific Navitimer model.
• Advance the Date: Continue turning the crown until the correct date appears in the date window.

4. Set the Time:

• Pull the Crown to the First Position: If you need to adjust the time, pull the crown out to the first position (the position closest to the watch case).
• Adjust the Time: Turn the crown to set the correct time. Make sure to align the time correctly to avoid any issues with the date mechanism.

5. Push the Crown Back:

• Ensure Proper Positioning: After setting the date and time, push the crown back in flush with the watch case.
• Secure the Crown: If your Navitimer has a screw-down crown, make sure to screw it back in to ensure water resistance.

6. Check the Date Transition:

• Advance the Time: To ensure the date changes correctly, advance the time to a few hours past midnight and check if the date has updated. This ensures that the date-change mechanism is functioning properly.

7. Regular Maintenance:

• Avoid Over-Adjusting: Frequent manual adjustment of the date can put stress on the mechanism. Try to adjust the date only when necessary.
• Service Your Watch: Regularly service your Breitling Navitimer to keep the movement in optimal condition and to prevent potential issues.

By following these steps, you can safely and accurately change the date on your Breitling Navitimer watch, maintaining its functionality and longevity.
