The Breitling Caliber 45, often referred to as the B45, isn't a groundbreaking, in-house creation boasting revolutionary technology. Instead, it represents a pragmatic approach by Breitling, leveraging a robust and reliable base movement from ETA, a renowned Swiss movement manufacturer, and modifying it to meet their specific needs and branding. This article will delve into the specifics of the Breitling Caliber 45, exploring its origins, specifications, the watches it powers, and its place within the broader context of Breitling's movement history, including a comparative look at other Breitling calibers like the Caliber 23, 17, and 13.
Who Makes Breitling Movements? A Look at In-House and External Sources
Before we dissect the Caliber 45, it's crucial to understand Breitling's approach to movement production. While Breitling has increasingly focused on developing its own in-house movements in recent years, signifying a commitment to independent manufacturing, a significant portion of their catalog has historically relied on modified ETA movements. The Caliber 45 exemplifies this strategy. Breitling's in-house movements, a testament to their horological expertise, are a subject of considerable interest among watch enthusiasts. These movements represent a higher level of vertical integration and often incorporate unique features and finishing. However, using established, reliable movements like the ETA 2834-2 allows Breitling to offer high-quality watches at a more accessible price point while maintaining quality control.
The Breitling Caliber 45: A Closer Look at the ETA 2834-2 Base
The Breitling Caliber 45 is essentially a modified ETA 2834-2. The ETA 2834-2 is a well-respected automatic movement known for its robustness and reliability. It's a workhorse movement, powering numerous watches from various brands. Breitling takes this proven base and customizes it, adding its own finishing touches, decoration, and potentially minor modifications to better suit the aesthetic and functional requirements of their watches. This customization extends to the rotor, bridges, and potentially the escapement, resulting in a movement that retains the reliability of the ETA base while reflecting Breitling's design language.
Specifications of the Breitling Caliber 45:
* Base Movement: ETA 2834-2
* Type: Automatic, self-winding
* Jewels: Typically 25
* Frequency: 28,800 vibrations per hour (4 Hz)
* Power Reserve: Approximately 38-42 hours (depending on specific modifications)
* Functions: Hours, minutes, seconds, date
* Finishing: Breitling typically applies its own finishing touches, including côtes de Genève, perlage, and possibly other decorative elements, depending on the watch model.
Watches Utilizing the Breitling Caliber 45:
A comprehensive list of all watches powered by the Caliber 45 would require access to Breitling's complete historical production records, which are not publicly available in a readily searchable database. However, identifying specific models requires detailed research through Breitling's official website, archival materials, and specialized watch databases. This is a task best suited for dedicated watch enthusiasts and researchers. Generally, the Caliber 45 has been used in Breitling's more entry-level to mid-range collections, offering a balance of quality and affordability.
