The Breitling Navitimer, a horological icon renowned for its sophisticated slide-rule bezel and intricate movement, can sometimes present a slight challenge to new owners when it comes to adjusting the date. Unlike many modern watches with independent date-setting mechanisms, the Navitimer often requires a specific procedure to accurately advance or rewind the date. This article will provide a comprehensive guide on how to change the date on your Breitling Navitimer, covering various models and addressing common questions. We'll delve into the mechanics behind the date-changing mechanism and offer troubleshooting tips, drawing parallels with information found in the official Breitling Navitimer user manual, owner's manual, and specific model instructions like the Breitling Navitimer A24322 manual and the Breitling Navitimer B01 manual. While the Breitling Emergency instructions are irrelevant to date setting, understanding your watch's specific manual is crucial. This guide aims to clarify the process, eliminating any confusion and ensuring you can confidently manage this aspect of your prized timepiece.
Understanding the Navitimer's Date Mechanism
The date-changing mechanism in a Breitling Navitimer is typically integrated with the hour hand movement. This means there isn't a separate crown or pusher dedicated solely to adjusting the date. This design choice, while perhaps less intuitive than independent date-setting mechanisms, contributes to the watch's overall robustness and classic aesthetic. The date wheel advances only once per day, at midnight. This is why simply turning the crown forward or backward won't directly change the date; you must carefully manipulate the hands to trigger the date-changing mechanism.
The Standard Method: Advancing the Date
The most common method for changing the date on a Breitling Navitimer involves the following steps:
1. Locate the Crown: Identify the crown on the right side of your watch case. This is the small knob used to wind the watch and set the time.
2. Pull the Crown to the Time-Setting Position: Gently pull the crown out to the first position. This will allow you to adjust the time. The number of clicks required to reach this position varies depending on the model, so refer to your specific Breitling Navitimer user manual or owner's manual for precise instructions.
3. Advance the Hands Past Midnight: Carefully rotate the crown clockwise to advance the hour and minute hands past midnight (12:00). This is crucial; the date will only change when the hands pass through midnight. Do this slowly and deliberately to avoid damaging the movement. Observe the date window; you should see the date change as the hands pass midnight.
4. Adjust the Time: Once the date has changed, continue rotating the crown to set the correct time.
5. Push the Crown Back In: Once the time is correctly set, gently push the crown back into its original, fully recessed position.
The Standard Method: Rewinding the Date
Rewinding the date requires a slightly more nuanced approach, and it's where many users encounter difficulties. The "fast forward, then rewind" method is commonly employed:
1. Pull the Crown to the Time-Setting Position: As before, pull the crown out to the time-setting position.
