Originally created to enable the watch wearer to determine the time in low light conditions, the chiming of the hours and minutes still represents a feat of technical virtuosity in the watchmaking industry. The Opera One watch incorporates a Westminster chime, which, for marking the hours, utilizes four hammers to play a melody of four different notes.
Another zest of the new Girard-Perregaux watch is a tourbillion. Engineered to eliminate the gravity effects on the timepiece's regulating organ, this complication reflects the best tradition cherished by the brand since the 19th century.
The Tourbillon with gold Bridges is one of the most remarkable achievements of Girard-Perregaux.
The three emblematic gold Bridges have been intentionally reinterpreted for the new watch in order to crown it with the chime mechanism. The Bridges exposes three of the four chime hammers - the fourth is seen when the watch chimes the hours.
The tinted sapphire dial of the Girard-Perregaux watch proudly exposes a sunburst finish. Its rays are stretching from the tourbillon, which is revealed at 6 o'clock. The hammers, striking the hours, are visible at 9 o'clock. The see-through case-back enables the watch owner to admire other exciting aspects of the watch’s extremely complex movement, which operates at a frequency of 21,600 vibrations per hour and incorporates 37 jewels. The movement provides a respectable 75-hour power reserve.
The entire mechanism is housed in a white gold case, which measures 40 mm in diameter. The timepiece is submersible to 30 meters.
The Girard-Perregaux Opera One Sapphire Dial watch is affixed to an alligator leather strap, which terminates in a folding buckle.
