The Opera Two model from the Girard-Perregaux Opera series was introduced in 2001.
The Girard-Perregaux Opera watch two combines three of the most distinguished and complex complications: the minute repeater, perpetual calendar and Tourbillon. It also offers the minute repeater function chimes with a “Westminster” carillon consisting of the use of four different gongs.
The cut out dial displays three of the four chime hammers, with the fourth only visible when the chime is active. The extraordinary complexity of the mechanical manual winding movement can be admired through the case’s transparent back. The mechanism has a power reserve exceeding 75 hours.
This extra-ordinary watch is an evolution of Girard-Perregaux Opera One, which incorporates a minute repeater with the “Westminster” chimes (mi-do-re-sol) and tourbillon with Three Gold Bridges. In the Opera two watch, the Manufacture has added the perpetual calendar function.
The Girard-Perregaux Opera Two watch is available in gold and platinum versions. It has a case diameter of 42mm.
