The Breitling Caliber 23 isn't a name that immediately leaps to mind when discussing iconic watch movements. However, this robust and reliable chronograph caliber, essentially a Breitling-modified version of the venerable Valjoux 7753, forms the backbone of several noteworthy Breitling timepieces. Its versatility and robust construction have cemented its place as a significant player in the Breitling catalog, powering both classic and limited-edition models. This article will delve into the specifics of the Caliber 23, exploring its specifications, variations, related calibers, and its presence in some of Breitling's most popular watches.
Breitling Caliber 23: The Foundation
The Breitling Caliber 23 is, at its core, a derivative of the ETA/Valjoux 7753, a well-regarded automatic chronograph movement known for its reliability and relatively straightforward design. Breitling, however, didn't simply adopt the movement; they significantly enhanced and modified it to meet their stringent quality standards and integrate it seamlessly into their watch designs. This involved adjustments to the finishing, decoration, and potentially some internal components to align with Breitling's aesthetic and performance goals. The result is a movement that shares the fundamental architecture of the 7753 but boasts a distinct Breitling identity.
One of the key features distinguishing the Caliber 23 is its availability in two primary configurations: with or without an hour totalizer. The version *with* the hour totalizer displays elapsed time up to 12 hours, adding a practical layer of functionality for longer timing events. The version *without* the hour totalizer prioritizes a cleaner, less cluttered dial layout, often preferred in sportier or more minimalist designs. This flexibility allows Breitling to tailor the movement to the specific aesthetic and functional requirements of each watch model.
Breitling Caliber 23 Specs:
* Base Movement: Modified ETA/Valjoux 7753
* Type: Automatic Chronograph
* Jewels: Typically 25 jewels (though this can vary slightly depending on specific modifications)
* Frequency: 28,800 vibrations per hour (4 Hz)
* Power Reserve: Approximately 42-48 hours (depending on specific implementation and usage)
* Functions: Hours, minutes, seconds, chronograph (seconds, minutes, and often hours), date.
* Variations: With or without hour totalizer.
The precise specifications might vary slightly depending on the specific watch model and any minor modifications implemented by Breitling over the years. However, the core specifications remain consistent across the Caliber 23 family.
Breitling 23 Movement: Variations and Derivatives
While the Caliber 23 itself is a modified 7753, it serves as the basis for other Breitling calibers. Unfortunately, Breitling's internal naming conventions aren't always transparent to the public, making it difficult to definitively list every derivative. However, we can confidently say that the Caliber 23's architecture has influenced subsequent Breitling movements. Further research and access to Breitling's internal documentation would be required to provide an exhaustive list of all related calibers.
