In 1936, Longines developed and patented what would become their most famous caliber: Caliber 13ZN. This chronograph movement was the most elaborate and was available in various versions, featuring a 30 or 60 minute counter and one or two pushers. The present reference 5699, bearing this prestigious caliber, displays a very specific feature. The watch features two central chronograph hands and is referred to amongst collector as the “Doppia Lancetta”, meaning two hands in English. These two centrally mounted hands not to be mistaken for a split seconds, serve to record the seconds and the minutes hence leading to the suppression of the minutes register. Produced for the American market, the movement of this watch is stamped with the Longines-Wittnauer import code: LXW. A noteworthy element to mention Longines’ specific numbering system where the case number was repeated on the upper left lugs, in this case 122. Reference 5699 further surprises by its considerable case size, measuring a dramatic 39.5mm in diameter. Rarely seen on the market, this “Doppia Lancetta” impresses not only by its size and presence but also represents tremendous value for the wise collector of vintage wristwatches.
