First launched in 2009, the Senator Chronometer series expanded in 2016 with reference 1-58-01-05-34-XX, which features a white gold case and a blue-grainé varnished dial accented with Roman numerals. Powered by the manual-wind caliber 58-01, the watch displays hours, minutes, small seconds at six, a Panorama Date at three, and a power reserve indicator at twelve. It comes on an alligator strap, offered with a pin buckle (01), a folding clasp (30), or a shorter folding clasp (50).
