Today's offering showcases a cool and classic original telemeter scale chronograph. The black dial and chrome and steel case give the watch a great let's get down to business look. The dial has a telemeter scale for easily calculating the distance of phenomena that can be both seen and heard, such as munitions blasts and thunderclaps. Powering the watch is a Landeron movement. For those unfamiliar with vintage chronographs, due to their complexity, in vintage times most brands, including firms like Rolex, Breitling, and Heuer, did not fully manufacture their own movements but rather purchased them from companies who specialized in making the mechanisms. Landeron was one of the well-known chronograph movement makers of the period. Their movements are best known for powering some of Heuer's and Baume et Mercier's chronographs, as well as watches from Gallet.
