The 42 mm case of this timepiece features a somewhat slimmer bezel than previous Senator models, allowing the bezel to serve as an elegant frame for the fine lacquered gray grained dial. The dial visuals feature Roman numerals and a classic railroad chapter ring engraved in the surface which subsequently receives an elegant silver inlay. The distinctive Panorama Date is presented in white on a dark ground beneath hour 12, and the 'poire' hands in white gold enhance the transcendent elegance of the design. Taking pride of place on the dial is the superb Flying Tourbillon with seconds indicator, positioned at six o'clock in harmonious counterpoint to the Panorama Date.
At the heart of the Senator Tourbillon is the exquisite automatic calibre 94-03, which has a power reserve of 48 hours. The Flying Tourbillon mechanism can be admired through the anti reflective sapphire crystal protecting the dial. The screw balance in the tourbillon cage features 18 weighted gold screws.
