Breitling's B20 caliber has been a subject of considerable discussion within the horological community since its introduction in 2017. Advertised as an "in-house" movement, its origins and design raise questions about the true meaning of the term and the implications for consumers. This article will delve into the details of the Breitling B20 movement, examining its performance, reported problems, and the controversies surrounding its classification, covering various Breitling models that utilize this caliber, including the Breitling Superocean B20 Automatic 42 and the Breitling Superocean Heritage B20 42mm.
Breitling B20 Movement Review: A Technically Capable but Debated Caliber
The Breitling B20 is an automatic movement, boasting a robust 70-hour power reserve, a significant improvement over many competitors in its price range. It features a silicon balance spring, known for its anti-magnetic properties and resistance to shock, contributing to enhanced accuracy and reliability. The movement also incorporates a COSC chronometer certification, a testament to its precision and adherence to stringent testing standards. On paper, the B20 presents a compelling case: a high-performance movement with a lengthy power reserve and a prestigious certification. Its relatively simple architecture contributes to its robustness and ease of maintenance.
However, the "in-house" label attached to the B20 has been the source of much debate. While Breitling assembles the movement in its own facilities, the fundamental design is based on a Tudor movement, co-developed and produced by Kenissi, a joint venture between Tudor and Breitling. This collaborative effort, while beneficial in terms of cost-effectiveness and economies of scale, muddies the waters when it comes to branding the B20 as wholly "in-house." Many enthusiasts argue that a truly in-house movement should be conceived, designed, and manufactured entirely within the brand's own facilities, without significant external contributions. This distinction is crucial for many consumers who value the heritage and craftsmanship associated with genuinely in-house movements.
The B20's performance in real-world use is generally positive. Many owners report excellent timekeeping, consistent with its COSC certification. The 70-hour power reserve is a practical advantage, allowing for extended periods without the need for winding. The movement's relatively straightforward construction contributes to its reliability and ease of servicing. However, like any mechanical movement, the B20 is not immune to potential issues.
Breitling B20 Movement Problems: Addressing Reported Issues
While the Breitling B20 generally enjoys a positive reputation for reliability, several issues have been reported by users. These are not widespread, but they're important to consider. Some owners have reported instances of minor timing inconsistencies or deviations from COSC standards over time. These minor discrepancies are often attributed to factors such as variations in temperature, wear, and individual movement tolerances. It's crucial to remember that even COSC-certified watches can exhibit slight variations in accuracy.
