It has a three time zone display, two on one dial and one on the other face. Mechanical ingenuity. All these displays work with a single movement, a single barrel. The watch consists of two main parts: a base in the form of a «cradle» in which sits the mobile case. A wheel at 12 o'clock releases the case. Just lift to make it pivot on an axis at 6 o'clock, then «reseat» it in its cradle, and screw the wheel back. The first dial of INSTRUMENTO DOPPIO TRE displays both a double time zone and the full date in a window at half past seven. The two time zones are displayed on superimposed counters. This highly geometrical design is beautiful. The contrasting materials in the smooth central zone give a dynamic look to the wavy guilloché-work. The case of INSTRUMENTO DOPPIO TRE pivots to reveal a third time zone with analogue hours and minutes display. INSTRUMENTO DOPPIO TRE is the first double faced watch to display the time at three points of the globe. The second dial here is located under the rotor, bearing the inscription INSTRUMENTO DOPPIO TRE. The hands cross the oscillating weight of the automatic movement. The rotor, constantly moving, covers some of the figures, depending on the position of the watch."
