Longines pushed the boundaries with the Chronostop in terms of both its aesthetic design and technical ingenuity. Longines chronographs are considered amongst the world’s best crafted, most attractive and, consequently, collectible watches. In addition to its excellent and original state of preservation, this single-button chronograph impresses with its unrestored glossy black dial and red center-minute recorder hand. Whereas most chronographs have two subsidiary dials, this reference Chronostop only features one. The result is greater legibility and better user friendliness. The largest variant of the model, its oversized “Brevet” (patented) case houses the Longines in-house, fly-back caliber 12.68Z. Similar to other Longines watches from this time era, one can still partially see on the underside of the lug a stamped ‘2’ to match the inside caseback number. The watch was developed for military use, making them very difficult to find in a good state of preservation. The condition of this single-button chronograph from 1949 is extraordinary, and combined with its technical excellence, attractiveness and exclusivity, it is a highly desirable timepiece for the connoisseur.
