The Senator Chronometer was released in 2009, and in 2016, the current model (ref. 1-58-01-05-34-XX) joined the collection. This version boasts a white gold case and a sophisticated varnish blue-grainé dial with Roman numerals. It runs on a manual winding caliber 58-01, which displays hours, minutes, small seconds at six, the famous 'Panorama Date' at three, and a power reserve indicator at twelve. You can choose from three variations, each with a different alligator strap: one with a pin buckle, one with a folding clasp, and one with a shorter folding clasp.
