The Tonda GT Chronograph with its substantial 42 mm diameter case in 18ct rose gold houses an integrated self winding chronograph calibre operating at a rate of 5 Hertz, i.e. 36,000 vibrations per hour, beneath the silver toned guilloché dial with its "triangular hobnail" motif. Short-time measurements are read off on the "Quantum Grey" or "Granata" subdials, judiciously positioned to structure the space harmoniously arranged and nicely balanced by the big date display appearing in a twin aperture at 12 o'clock.
