de GRISOGONO Instrumento Doppio

Introduced in 2002, this exceptional mechanical timepiece has been baptised Instrumento Doppio’ by virtue of its double-faced case, giving a choice of either a dial with chronograph functions/big date or a dial showing a second time zone.

Born two years after Instrumento N° Uno as a tribute to the numeral 2, Instrumento Doppio features an ingenious pivoting-case construction that enables two complications based on a single movement, each displayed on opposite dials: an oversized date calendar (in twin apertures) and a second time zone.

The chronograph dial displays hours, minutes and chronograph functions along with a particularly legible oversized date calendar in twin apertures at 12 o’clock. On the opposite side, the second time-zone dial features an analog display of hours and minutes. Its strikingly unorthodox construction has the hands rotating directly through the oscillating weight that winds the movement. In contrast to a traditionally cased-up movement, this time the dial is under the rotor, which is inscribed with the words “Instrumento Doppio”, and briefly obscures some of the dial figures as it moves constantly.

From a technical point of view, the Instrumento Doppio broke new ground. Both of its analog displays are driven by the same movement and barrel, on which de GRISOGONO’s watchmakers have fitted an auxiliary chronograph module.

On the other side, they developed an exclusive, integrated mechanism made of two modules: one displays a time zone and the other resets it. 83 new components had to be designed for this now-patented device. For the first time ever, it combines a double analogue display and a hands system that goes through the oscillating weight.
