The Breitling B13050.1, a reference number designating a specific model within the iconic Breitling Chronomat line, houses a sophisticated automatic movement that's crucial to understanding its performance and value. While the exact caliber isn't explicitly stated in the provided reference ("Caliber/movement: ."), we can deduce much from the watch's characteristics and similar Breitling models. This article will explore the B13050.1's likely movement, delve into its specifications, compare it to related models, and examine its place within the Breitling Chronomat lineage, addressing common searches like "breitling b13050 specs," "breitling chronomat b13050 price," and "breitling 13050.1."
Identifying the Movement: A Deductive Approach
The absence of a specific caliber number in the original description requires a bit of detective work. Given the "Chronomat Bicolor Date" designation and the era suggested by the listing (a used watch), we can reasonably assume the B13050.1 utilizes a movement from Breitling's own family of automatic chronographs. Several possibilities exist, and pinpointing the exact one requires examining the watch physically or consulting detailed service records. However, we can analyze likely candidates based on Breitling's history and the Chronomat's typical specifications.
During the period when the B13050.1 was likely produced, Breitling predominantly used ETA-based movements, often heavily modified and decorated to meet their exacting standards. It's highly probable that the B13050.1 houses a modified version of an ETA Valjoux 7750 or a closely related caliber. The ETA 7750 is a workhorse movement known for its reliability, robustness, and modularity, making it a perfect base for a chronograph. Breitling's modifications would likely involve enhanced finishing, adjustments for precision, and potentially the addition of Breitling-specific components.
Exploring Potential Calibers and their Features:
Several ETA-based movements could be candidates for the B13050.1:
* Modified ETA Valjoux 7750: This is the most likely candidate. The 7750 is a highly versatile automatic chronograph movement with a column-wheel mechanism, known for its smooth operation and accurate timing. Breitling's modifications would likely focus on enhancing the aesthetics (Côtes de Genève decoration, perlage, etc.), improving timekeeping accuracy through regulation, and integrating it seamlessly into the Chronomat case. The date complication mentioned in the original description is a standard feature of the 7750.
* Variations of the 7750: Breitling often tweaked ETA bases, leading to slight variations. These variations might involve changes to the rotor design, adjustments to the power reserve, or modifications to the chronograph mechanism. Pinpointing the exact variation without access to the movement itself is impossible.
* In-House Movements (Less Likely): While Breitling has increasingly focused on in-house movements in recent years, during the period the B13050.1 was likely manufactured, the use of modified ETA movements was far more common. Therefore, an in-house movement is less probable, but not entirely impossible.
