Girard-Perregaux Opera two is an exceptional watch that combines three of the most distinguished and complex complications: the minute repeater, perpetual calendar and Tourbillon. As an additional sophistication, 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 refined Tourbillon movement can be admired through the case’s transparent back. The manual winding mechanism has a power reserve exceeding 75 hours.
