Resetting your Breitling Endurance Pro most commonly refers to the precise calibration and alignment of its chronograph hands to their default zero (12 o'clock) position. This procedure is crucial for maintaining the watch's accuracy and ensuring its timing functions operate correctly, especially after events like a battery change or an impact.
Understanding Hand Alignment for Your Endurance Pro
Unlike a simple chronograph reset after timing an event, this process involves recalibrating the physical alignment of the watch's hands. This ensures they consistently return to the exact 12 o'clock mark.
Step-by-Step Hand Alignment Procedure
To precisely align the hands on your Breitling Endurance Pro, follow these steps:
- Pull the Crown: Gently pull the crown out to position 2. This action typically stops the watch's movement and puts it into adjustment mode.
- Select the Hand: Press push-button A (usually located at the 2 o'clock position on the watch case). Each press will select a different hand that can be adjusted. The selected hand (e.g., chronograph seconds hand, minute counter) will usually complete a full revolution to indicate it's ready for adjustment.
- Adjust to 12 O'clock: Once a hand is selected, press push-button B (typically at the 4 o'clock position) to move the hand. Continue pressing push-button B until the selected hand points precisely to the 12 o'clock mark. You may need to press multiple times for fine adjustments. Holding the button down can sometimes move the hand more quickly.
- Repeat for Other Hands: If other hands (like the chronograph minute or hour counters) also require adjustment, repeat steps 2 and 3 for each of them.
- Push the Crown Back In: Once all necessary hands are aligned to 12 o'clock, push the crown firmly back into position 0. This will restart the watch movement and lock in your adjustments.
When to Perform Hand Alignment
You might need to perform this hand alignment procedure in several situations:
- After a Battery Change: Replacing the battery can sometimes affect the precise calibration of the hands.
- Inaccurate Zero Return: If your chronograph hands do not return exactly to the 12 o'clock position after you've stopped and reset the chronograph, alignment is necessary.
- Following Impact: A significant knock or drop could cause hands to become misaligned.
- Periodic Maintenance: To ensure the highest level of precision for your timing functions.
Differentiating from Standard Chronograph Reset
It's important to distinguish between hand alignment and the regular use of your watch's chronograph function.
- Standard Chronograph Operation: When you use the chronograph to time an event, you typically press push-button A to start, push-button A again to stop, and then push-button B to reset the timing hands back to zero. This is a routine operational reset.
- Hand Alignment (Calibration): The procedure detailed above is for calibrating the home position of these hands, ensuring that their 'zero' point is truly 12 o'clock, which is fundamental for accurate timing.
Quick Reference: Button Functions for Hand Alignment
| Component | Function (Hand Alignment Mode) |
|---|---|
| Crown | Pulled to Position 2: Activates hand adjustment mode |
| Push-button A | Selects the specific hand to be adjusted (e.g., chrono seconds, minutes) |
| Push-button B | Moves the selected hand incrementally to the 12 o'clock position |
Tips for Best Results
- Stable Surface: Perform the alignment on a flat, stable surface to minimize movement.
- Good Lighting: Ensure adequate lighting to clearly see the 12 o'clock markers and hand positions.
- Consult Your Manual: While this guide provides a general procedure, always refer to the specific user manual for your Breitling Endurance Pro model for any unique details or additional functions. You can often find digital manuals on the official Breitling website.
By following these steps, you can ensure your Breitling Endurance Pro's chronograph hands are perfectly aligned, maintaining the precision and reliability you expect from your timepiece.
