The Breitling 1806, specifically those housing the legendary Caliber 11 movement, represent a pivotal moment in horological history and a highly sought-after piece for vintage watch collectors. This article will explore the intricacies of the Breitling 1806 Cal. 11, delving into its design, history, technical specifications, and the factors that contribute to its enduring appeal and substantial value in today's market.
The reference 1806 embodies the classic Breitling Navitimer design, synonymous with aviation history and precision timekeeping. Its distinctive circular slide rule bezel, a hallmark of the Navitimer line, allows for complex calculations essential to pilots – from fuel consumption to flight time and distance. This functionality, combined with its chronograph capabilities, makes the 1806 a highly versatile and historically significant timepiece. But it's the Caliber 11 nestled within its case that truly elevates this watch to iconic status.
The Caliber 11 is not just any chronograph movement; it represents a significant technological leap in the late 1960s and early 1970s. Developed as a joint venture between Breitling, Heuer (now TAG Heuer), Buren, and Dubois-Dépraz, the Caliber 11 was one of the first commercially successful automatic chronograph movements. This collaborative effort was a response to the burgeoning popularity of quartz technology, which threatened the dominance of mechanical watches. By creating a high-quality, reliable automatic chronograph, these companies aimed to solidify the position of mechanical movements in the face of this new challenge. The success of the Caliber 11 proved instrumental in the survival and continued evolution of mechanical chronographs.
The architecture of the Caliber 11 is a testament to its innovative design. Unlike traditional column-wheel chronographs, the Caliber 11 utilized a cam system for chronograph actuation. This design, while less elegant in some respects, allowed for a more compact and cost-effective construction, making the automatic chronograph more accessible to a wider market. This pragmatic approach did not compromise performance; the Caliber 11 offered robust functionality and accuracy, exceeding the expectations of the time.
The 1806 models equipped with the Caliber 11 frequently featured a distinctive dial layout, often characterized by three sub-dials arranged in a tri-compax configuration. The sub-dials typically displayed running seconds, 30-minute counter, and 12-hour counter. These dials, usually in a contrasting color against the main dial, provided a clear and legible display of chronograph functions. The overall aesthetic is one of classic elegance and purposeful design, reflecting the functional nature of the watch and its intended use in the cockpit.
