The Breitling Navitimer, a watch synonymous with aviation history and horological excellence, boasts a rich and complex lineage. Within that lineage, the first-generation Navitimer 806 holds a particularly coveted place, largely due to its association with a range of movements, most notably the hand-wound Venus 178 chronograph caliber. This article delves deep into the fascinating story of the Breitling Navitimer 806, focusing specifically on those models equipped with the legendary Venus 178 movement, exploring its technical intricacies, historical significance, and the variations found within this iconic watch family.
The Breitling Navitimer 806: A Brief Overview
The Breitling Navitimer 806 represents a pivotal moment in the Navitimer's evolution. Preceding the more widely recognized later iterations, the 806 marked a transition period for the brand, experimenting with different case designs, dial configurations, and, crucially, movements. While the iconic circular slide rule bezel remained a constant, the internal mechanisms varied considerably. This variability contributes significantly to the collectability and allure of the 806, making each example unique and worthy of detailed examination. The 806's production period is generally understood to span the late 1950s through the mid-1960s, although precise dates are difficult to pin down due to the staggered introduction of different movements and case variations.
The watch's design itself is a testament to Breitling's commitment to functionality and readability. The prominent slide rule bezel, designed for complex aviation calculations, remains the defining feature. The dial, typically featuring contrasting subdials and clear Arabic numerals, ensured quick and easy interpretation of time and flight data, even under challenging conditions. The case, usually stainless steel, provided robust protection for the delicate movement within. This combination of form and function solidified the Navitimer's reputation as the quintessential pilot's watch.
The Venus 178 Movement: A Mechanical Masterpiece
The Venus 178 is a hand-wound chronograph movement that holds a special place in watchmaking history. Produced by the Venus Watch Company, a prominent Swiss movement manufacturer, the 178 caliber was renowned for its reliability, robust construction, and distinctive column-wheel architecture. This column-wheel mechanism, a hallmark of high-quality chronograph movements, ensured smooth and precise operation of the chronograph functions – start, stop, and reset. Unlike cam-actuated systems, the column wheel provides a more refined and tactile feel, contributing to the overall pleasure of using the chronograph.
The Venus 178's design was characterized by its compact size and relatively high beat rate for its time, contributing to improved accuracy and smoothness of operation. Its intricate construction, visible through the case back on some models, is a testament to the craftsmanship of the era. The movement's intricate bridges, meticulously finished gears, and precisely adjusted components are a visual delight for any horological enthusiast. The use of the Venus 177 and Venus 178 movements in the Breitling Navitimer 806 cemented the watch's reputation for quality and precision, appealing to professional pilots and watch collectors alike.
