The Breitling Navitimer, a watch synonymous with aviation history and sophisticated design, boasts a rich lineage of movements. Among the most celebrated is the Venus 178, often referenced as the "Breitling 806" movement, a testament to its crucial role in the brand's iconic chronograph watches. This article delves deep into the intricacies of this manual-wind marvel, exploring its features, history, and its continuing desirability in the collector's market. We'll also examine pricing, availability, and the factors contributing to the value of vintage examples bearing this legendary caliber.
Movement & Features: The Heart of the Navitimer
The Breitling 806 movement, in reality the Venus 178, is far more than just a timekeeping mechanism; it's a piece of horological history. Produced by the renowned Venus Watch Company, this column-wheel chronograph movement is renowned for its reliability, precision, and elegant construction. Its key features include:
* Venus 178 Caliber: The heart of the matter. This manually wound movement is a testament to the craftsmanship of a bygone era. Its robust design ensured accuracy and longevity, qualities highly valued by pilots and adventurers who relied on their Navitimers in demanding conditions.
* Manual Winding: Unlike modern automatic movements, the Venus 178 requires manual winding. This interaction with the watch, the feeling of the crown turning and the mechanism springing to life, is part of its charm and contributes to the connection between wearer and timepiece.
* 45-Hour Power Reserve: A respectable power reserve for a manual-wind chronograph, allowing for several days of wear without rewinding. This extended power reserve speaks to the efficient design of the Venus 178.
* 18,000 vph (Vibrations Per Hour): This relatively lower beat rate compared to modern movements contributes to the smooth and steady operation of the chronograph function. The lower frequency is also associated with greater robustness and durability.
* Chronograph Function: The hallmark feature. The Venus 178 boasts a classic chronograph layout with independent start, stop, and reset functions. The precise operation of the chronograph is a testament to the quality of the movement's construction. The crisp action of the pushers and the clear indication of elapsed time are key elements of the user experience.
* Slide Rule Bezel: While not technically part of the movement itself, the slide rule bezel is inextricably linked to the Breitling 806's identity and functionality. This ingenious feature allowed pilots (and later, enthusiasts) to perform complex calculations, including speed, distance, fuel consumption, and conversion calculations, directly on the watch. The combination of the chronograph and the slide rule bezel made the Navitimer a uniquely practical and versatile tool watch.
