The Breitling Calibre B20, introduced in 2017, represents a significant chapter in the brand's history, marking a shift in their approach to movement manufacturing. While Breitling proudly proclaims it as an "in-house" movement, a closer look reveals a fascinating story of collaboration and strategic partnerships that ultimately deliver a reliable and robust automatic caliber. This article will delve into the intricacies of the Breitling Calibre B20, exploring its origins, specifications, performance, and its place within the broader Breitling watch ecosystem. We'll cover aspects ranging from its technical specifications to its use in various Breitling models, addressing common queries surrounding the B20, including the often-misunderstood nature of its "in-house" designation.
Breitling B20: More Than Just a Movement
The Breitling Calibre B20 is more than just a collection of gears and springs; it's a key component in several popular Breitling watch lines, most notably the Avenger and Navitimer collections. Its robust construction and reliable performance make it a perfect fit for these tool watches, known for their durability and precision. Understanding the B20 is crucial to appreciating the overall quality and value proposition of these timepieces.
Breitling B20 Caliber: A Technical Overview
At its core, the Breitling Calibre B20 is an automatic movement designed for optimal reliability and longevity. While Breitling markets it as an in-house movement, it’s important to clarify that it's based on a movement design developed in collaboration with Kenissi, a joint venture between Tudor and Breitling. This collaboration allows Breitling to leverage the expertise and manufacturing capabilities of Kenissi, resulting in a high-quality movement at a competitive price point. The shared design philosophy between Tudor and Breitling allows for economies of scale, benefiting both brands.
The Calibre B20 is a self-winding movement, meaning it automatically winds itself through the natural motion of the wearer's wrist. This eliminates the need for manual winding, offering convenience and ease of use. The movement boasts a significant power reserve, typically around 70 hours, ensuring the watch continues to run even if it's not worn for an extended period. This extended power reserve is a significant advantage over movements with shorter power reserves, offering greater practicality for everyday wear.
The Calibre B20 features a high frequency of 28,800 vibrations per hour (4 Hz), contributing to its accuracy and precision. This frequency is common in high-quality automatic movements and ensures smooth, consistent timekeeping. The movement is constructed with high-quality components, ensuring durability and resilience against the rigors of daily wear. The use of modern manufacturing techniques and material selection further enhances the movement's reliability and longevity.
Breitling B20 Automatic Movement: A Deeper Look at Functionality
The automatic winding mechanism of the Calibre B20 uses a bidirectional rotor, meaning it winds the mainspring whether the watch is rotated clockwise or counterclockwise. This efficient design maximizes the energy generated from the wearer's wrist movements, contributing to the extended power reserve. The movement also incorporates a date function, displayed neatly in a window at the 3 o'clock position, a practical and user-friendly feature.
