The Breitling Calibre 45, while not as widely discussed as some of its sibling movements like the Breitling 17, represents a significant piece of the brand's horological history. While lacking the extensive online reviews and detailed specifications readily available for other calibres, its position within the Breitling family merits a closer examination, especially when considering its context within the broader landscape of Breitling automatic movements. This article will delve into the known aspects of the Calibre 45, comparing and contrasting it with the more frequently discussed Breitling 17, and exploring its place within the brand's legacy of robust and reliable timepieces.
Understanding the Breitling Calibre 45: A Foundation in ETA
The Breitling Calibre 45 is an automatic mechanical movement, a designation signifying its self-winding capability through the wearer's natural movements. Crucially, it's based on an ETA movement, a practice common among many watch manufacturers, including Breitling. ETA, a subsidiary of the Swatch Group, produces a wide array of reliable and cost-effective movements that serve as the foundation for numerous brands' timepieces. This reliance on established base movements allows Breitling to focus on its design and finishing, integrating these movements into their signature aesthetics and functionalities.
While the exact ETA base movement for the Calibre 45 isn't explicitly detailed in readily accessible public information, its classification as an "automatic mechanical" indicates a lineage within ETA's range of automatic calibres. This points towards a robust and proven mechanism, likely incorporating features such as a central rotor for winding and a balance wheel for regulating the timekeeping. The lack of specific ETA model identification highlights a common practice: manufacturers often modify and enhance base movements to meet their specific requirements, resulting in a final product that, while based on an existing calibre, possesses unique characteristics and performance attributes.
Comparing the Calibre 45 with the Breitling 17: A Tale of Two Calibres
The Breitling 17, frequently searched for under terms like "Breitling caliber 17 movement review," "Breitling 17 movement review," "Breitling caliber 17 review," "Breitling b17 movements," and even "Breitling 17 jewels," occupies a significantly more prominent position in online discussions and enthusiast forums. This is likely due to its broader use across various Breitling models, including popular series like the Superocean (e.g., Breitling Superocean A17366). The Breitling 17, also based on an ETA movement, is known for its reliability and relatively straightforward design. Its popularity stems from its successful integration into numerous Breitling watches, offering a balance of functionality and affordability.
The key difference between the Calibre 45 and the Breitling 17 lies primarily in their usage and the specific watches they powered. While both are automatic mechanical movements with ETA foundations, the Calibre 45 appears to have been used in a more limited range of models, resulting in less readily available information and fewer user reviews. This isn't necessarily indicative of inferior quality; rather, it simply reflects its smaller market presence compared to the widely adopted Breitling 17.
