The 1/10^thSecond Chrono with Rare Bracelet

We are offering a rare and unusual Longines Chronograph – the Nonius Fly-Back. Named after the Portuguese mathematician P Nunes, the Nonius is a minutes, seconds and 1/10th second timer. Housed in a robust, 41mm pillow-form steel case, this watch houses the original single minutes sub-register dial in perfect condition. The yellow chronograph hand features a unique attached-scale that can measure 1/10ths of a second. The watch houses the high-quality calibre 538, which is based on the iconic 30ch movement, the successor to the iconic 13ZN movement. Not all Nonius models have this movement, which makes this the most desirable version. The watch comes on the original steel bracelet, which is exceedingly rare to see. The watch has been fully serviced by our watchmaker.
