The world of vintage chronographs is a treasure trove of horological history, filled with iconic designs and groundbreaking movements. Within this world, certain pieces stand out, commanding attention and respect not just for their aesthetics but for their place in the narrative of watchmaking innovation. Among these highly sought-after timepieces is the Breitling Navitimer Pre-Series Cal. 11, a watch that represents a pivotal moment in the history of both Breitling and the automatic chronograph. This article delves deep into the allure and significance of this exceptionally rare and historically important watch, focusing on a specific example: a 1968 reference 1806, arguably from the very first production batch equipped with the groundbreaking Caliber 11.
This particular 1968 Breitling Navitimer ref. 1806 pre-series, with its Caliber 11 movement, is more than just a watch; it's a piece of living horological history. Its rarity is amplified by the fact that it hails from the very first production run of Navitimers fitted with this revolutionary movement. The term "pre-series" itself hints at the exclusivity and experimental nature of these early examples. These watches, produced before full-scale production commenced, often exhibit subtle variations in dial details, case finishing, and even movement construction, making each one a unique artifact. Finding an all-original, unrestored example like this is a feat in itself, a testament to the careful preservation it has received over the decades.
The Breitling Navitimer, in its own right, is an icon. Introduced in 1952, it quickly became a favorite among pilots and aviation enthusiasts for its ingenious slide-rule bezel, allowing for complex flight calculations at a glance. Its enduring design, characterized by its distinctive circular slide rule and easily recognizable dial layout, cemented its place as a timeless classic. However, the integration of the Caliber 11 movement into the Navitimer marked a significant evolution, transforming a celebrated mechanical masterpiece into a symbol of technological advancement.
The Caliber 11, a collaborative effort between Breitling, Heuer (now TAG Heuer), Buren, and Dubois-Dépraz, was a groundbreaking achievement. It represented the first commercially available automatic chronograph movement, a feat of engineering that overcame significant technical hurdles. Prior to its introduction, chronograph movements were predominantly manually wound, limiting their practicality and convenience. The Caliber 11's automatic winding mechanism was a game-changer, offering a more user-friendly and efficient chronograph experience. Its incorporation into the Navitimer, a watch already renowned for its functionality, created a truly exceptional timepiece, blending classic design with cutting-edge technology.
