The intricate mechanisms and workings of a timepiece have forever fascinated me. As if the already existing models are not complicated enough, Girard-Perregaux Manufacture has unveiled yet another complex timepiece. The timepiece, a unique version of the Opera One model with Tourbillon and minute repeater, was originally developed to allow the time to be determined in the dark. The unique version of the Opera One timepiece has achieved a technical feat, boasting of a Westminster chime, which marks the hours using four hammers to play a melody of four different notes! The shape of the three signature Girard-Perregaux gold Bridges on this watch is tactfully redesigned to incorporate the chime mechanism, revealing three of the four chime hammers with the fourth appearing when the chime sounds.
Featuring an 18ct white gold case (measuring 40mm), this timepiece is powered by a manual-wind Girard-Perregaux caliber GP9899 with 37 jewels, 21,600 vph movement. What distinguishes this timepiece from its original version is the semi-transparent tinted sapphire dial, which offers a remarkable view of its impressive movement. The alligator strap adds the finishing touches to this beautiful mechanical genius timepiece with an 18ct folding buckle.
A collector’s edition, this timepiece is water-resistant up to 30 meters and has a power reserve of 72 hours.
