The Breitling Caliber 17, often simply referred to as the B17, holds a unique position within the Breitling family. While Breitling is renowned for its in-house movements and high-end complications, the Caliber 17 represents a strategic approach to offering chronometer-certified accuracy at a more accessible price point. This article delves deep into the specifics of the Breitling Caliber 17, addressing its base movement, its certification, common misconceptions, and its place within the broader context of Breitling's horological offerings.
The Foundation: Sellita SW200-1 – Not an In-House Movement
Contrary to initial impressions, the Breitling Caliber 17 is *not* an in-house movement. It's based on the widely respected Sellita SW200-1 automatic movement. This is a crucial point to understand. Breitling, a brand synonymous with high-performance and innovation, often utilizes modified or enhanced versions of established movements from reputable suppliers. The Sellita SW200-1, a close relative to the ETA 2824-2 (a movement previously used extensively by many watch brands), provides a solid and reliable foundation upon which Breitling builds.
The choice to use a Sellita movement is a calculated one. Developing and producing in-house movements requires significant investment in research, development, manufacturing infrastructure, and skilled personnel. By using a proven and readily available movement like the SW200-1, Breitling can control costs and maintain a competitive price point for watches equipped with this caliber. This allows them to offer a chronometer-certified watch to a broader audience who might not otherwise be able to afford a Breitling with a fully in-house movement.
COSC Certification: The Hallmark of Accuracy
One of the most significant features of the Breitling Caliber 17 is its certification by the Contrôle Officiel Suisse des Chronomètres (COSC). This independent testing institute rigorously evaluates each movement for accuracy, subjecting it to a series of tests under varying conditions. Only movements that meet stringent criteria, typically maintaining a daily rate within a specific range (-4 to +6 seconds), receive the coveted COSC certification. This certification is a significant selling point, guaranteeing a high level of precision and reliability. The inclusion of COSC certification in a watch based on the Sellita SW200-1 is a testament to Breitling's commitment to quality, even within its more accessibly priced models. It elevates the Caliber 17 beyond a simple, mass-produced movement, positioning it as a serious contender in the entry-level luxury watch market.
Breitling's Modifications: More Than Just a Rebrand
While the Breitling Caliber 17 shares its DNA with the Sellita SW200-1, it's not simply a rebranded movement. Breitling engineers implement various modifications and enhancements to ensure it meets their exacting standards. These modifications often involve adjustments to the finishing, the addition of specific components, and potentially modifications to the regulating system to achieve the required accuracy for COSC certification. While the exact details of these modifications are often kept proprietary, the resulting movement is undeniably a Breitling product, carrying the brand's reputation for robust performance and reliability.
