The Breitling Chronometre B-1, a robust and sophisticated chronograph, offers a compelling blend of functionality and style. Understanding its bezel and chronograph functions is key to fully appreciating its capabilities. This comprehensive guide delves into the intricacies of reading the Breitling Chronometre B-1's bezel, exploring its various components and their interaction to accurately measure elapsed time. We'll examine the three registers, the central chronograph hand, and the crucial role of the pushers in initiating, stopping, and resetting the chronograph function. We'll also touch upon related Breitling models and their manuals to provide a broader context for understanding chronograph operation.
I. Understanding the Breitling Chronometre B-1 Chronograph Function
The Breitling Chronometre B-1's chronograph mechanism allows for precise time measurement beyond the standard watch function. This is achieved through a combination of three registers (sub-dials) and a central chronograph seconds hand. The measurement is made in hours (totalizer 1), minutes (totalizer 2), seconds, and 1/4 of a second (hand 3). This multi-layered approach provides a highly detailed record of elapsed time, making it ideal for various applications, from timing sporting events to monitoring complex processes.
A. The Registers (Totalizers):
* Totalizer 1 (Hours): This register typically displays elapsed time in hours. It advances incrementally with each completed hour of chronograph operation. It's crucial for measuring longer durations where the minutes and seconds registers would cycle multiple times.
* Totalizer 2 (Minutes): This register tracks elapsed time in minutes. It moves forward with each completed minute of chronograph operation. This register provides a clear indication of the minutes elapsed during the timing process.
* Hand 3 (Seconds and 1/4 Seconds): This is the central chronograph hand, often a contrasting color for better visibility. It measures elapsed seconds and, in the case of the B-1, increments in 1/4 second intervals. This level of precision allows for highly accurate timing, a key feature for professionals and enthusiasts alike.
B. Operating the Chronograph:
The chronograph function is controlled by two pushers, typically located at 2 and 4 o'clock on the watch case.
* Pusher A (Start/Stop): Pressing this pusher initiates the chronograph function, starting the movement of all three registers and the central seconds hand. Pressing it again stops the chronograph, freezing the elapsed time displayed on the registers.
* Pusher B (Reset): Pressing this pusher resets the chronograph to zero, returning all registers and the central seconds hand to their starting positions. This is essential for beginning a new timing sequence.
II. MEASURING ELAPSED TIME WITH THE BREITLING CHRONOMETRE B-1:
To measure elapsed time using the Breitling Chronometre B-1, follow these steps:
1. Start the Chronograph: Press pusher A to begin timing. All three registers and the central seconds hand will start moving simultaneously.
2. Monitor the Elapsed Time: Observe the positions of the central seconds hand, the minutes register (totalizer 2), and the hours register (totalizer 1) to determine the elapsed time. Remember that the central seconds hand indicates seconds and fractions of a second, while the other registers provide the minute and hour components of the measurement.
