From 1967 to 1978, the Canadian Air Force entrusted Breitling with crafting an exclusive single-pusher chronograph tailored for their elite pilots. This collaboration birthed five distinct models, each limited to a run of 1,000 pieces, culminating in a total of just 5,000 units. The subtle differences between these models are reflected in the unique engravings on the case back and movement bridges. We are delighted to present an exquisite 5th model from the late 1970s, distinguished by its rare NATO code "6645/21/802/1267." The dial exudes understated elegance, free from the manufacturer's logo, making it a true aficionado's treasure. Its Breitling lineage is subtly revealed only through the engraving on the crown. Despite being a single-pusher chronograph, this watch features a hacking function, offering the full capabilities of a two-pusher design. The case remains in remarkable condition, with flawless proportions and no evidence of prior polishing, only minor scratches from storage. The dial is immaculate, showing minimal signs of dirt or aging, preserving a clean and sharp appearance. The prints and textures are exceptionally well-maintained, with no signs of water damage. The luminous material has aged uniformly, adding to its vintage allure. Our skilled team has meticulously overhauled this timepiece, confirming a power reserve that exceeds 48 hours. Given its exclusive military origin, no civilian versions were ever produced, making this watch a genuine rarity. Finding such a piece in pristine condition is extraordinarily uncommon, amplifying its desirability. This is an extraordinary opportunity to own a piece of horological history that is as rare as it is functional. Seize the chance to add this historically significant and impeccably preserved Breitling to your collection.
