The Breitling Caliber 17, often referenced as the B17 movement, represents a significant chapter in the brand's history. While not a wholly in-house movement like some of Breitling's more recent offerings, the Caliber 17 holds a special place due to Breitling's meticulous finishing and enhancement of a high-grade ETA ébauche. This article will explore this fascinating movement in detail, addressing its specifications, performance, history, and its place within the broader Breitling lineup, particularly within watches like the Breitling Superocean A17366. We will also delve into common questions surrounding the Caliber 17, such as its jewel count and its self-winding capabilities.
Breitling Caliber 17 Movement Review: Unpacking the Swiss Precision
The Breitling Caliber 17 isn't a movement Breitling designed from the ground up. Instead, it begins its life as a high-grade ETA ébauche, a semi-finished movement blank. This is a common practice in the watch industry, allowing brands to leverage existing, reliable bases while focusing their resources on finishing, regulation, and incorporating their unique design elements. What sets the Caliber 17 apart is the significant work Breitling performs on this base movement. It's not simply a matter of slapping on a Breitling rotor and calling it a day. The Caliber 17 undergoes a rigorous process at Breitling Chronométrie in La-Chaux-de-Fonds, Switzerland. This involves meticulous assembly, careful adjustment, and rigorous testing to ensure the movement meets Breitling's exacting standards of quality and performance.
This process elevates the ETA base movement beyond its standard specifications. While Breitling remains tight-lipped about the precise nature of their modifications, the resulting Caliber 17 demonstrates a noticeable improvement in accuracy, reliability, and overall robustness compared to a standard ETA movement. This commitment to quality is a hallmark of Breitling's approach, even when utilizing a third-party ébauche. The result is a movement that performs admirably and reflects the brand's dedication to delivering a superior product.
Breitling 17 Movement Review: Beyond the Basics
The Caliber 17 is a self-winding automatic movement, meaning it utilizes the natural movement of the wearer's wrist to wind the mainspring. This eliminates the need for manual winding, providing convenience and consistent power reserve. The self-winding mechanism is typically highly efficient, ensuring that the watch maintains power even with moderate daily wear. The power reserve of the Caliber 17 is generally cited as around 42 hours, though this can vary slightly depending on individual usage and conditions. This power reserve is sufficient for most daily wear scenarios, allowing the watch to continue running even if it's removed for a period overnight.
The movement's automatic winding system operates smoothly and silently, a testament to Breitling's meticulous assembly and quality control. The rotor, which is responsible for transferring the kinetic energy of the wrist movement into the mainspring, is typically decorated with the Breitling logo and other aesthetic embellishments, adding a touch of luxury to the movement's visible components.
