The Breitling Caliber 45, often simply referred to as the B45, represents a significant chapter in Breitling's history, showcasing the brand's commitment to robust, reliable, and aesthetically pleasing automatic movements. While not a wholly in-house manufactured movement like the prestigious B01, the Caliber 45 nonetheless holds a prominent place in Breitling's lineup, powering several popular models within their diverse collection. This article will delve into the specifics of the Breitling Caliber 45, exploring its specifications, origins, applications, and place within the broader context of Breitling's movement strategy.
Understanding the Breitling Caliber 45: Specifications and Origins
The Breitling Caliber 45 (B45) is an automatic mechanical movement, a hallmark of Breitling's commitment to traditional horological craftsmanship. Its core is based on a modified ETA movement, a practice common among many watch manufacturers, allowing for cost-effective production while still maintaining a high standard of quality and reliability. While Breitling doesn't publicly specify the exact ETA base movement used, it's understood to be a robust and well-regarded caliber known for its durability and accuracy. This foundation allows Breitling to focus on their design and finishing processes, incorporating their distinctive aesthetic and functionality.
The key specifications of the Breitling Caliber 45 generally include:
* Caliber: Breitling 45 (B45)
* Movement Type: Automatic Mechanical
* Base Movement: Modified ETA (exact model not publicly disclosed)
* Power Reserve: Typically around 42 hours, although this can vary slightly depending on the specific watch model and individual variations in the movement.
* Frequency: The standard frequency is likely 28,800 vibrations per hour (4 Hz), consistent with many ETA calibers.
* Jewels: The exact number of jewels is not always explicitly stated but is likely in the range typical of ETA movements of similar complexity.
* Functions: The basic Caliber 45 offers hours, minutes, and seconds. However, depending on the watch model it is integrated into, additional complications like a date window (as seen in the Breitling Premier Day & Date) or day/date functionality (as in the Aviator 8 Automatic Day & Date 41) might be incorporated.
