A masterpiece of elegance and technology, the Girard-Perregaux 1966 Minute Repeater unveils a magnificent mechanism that produces an intense sound. Its acoustic merits and the purity of its lines rely on over 220 years of tradition and excellence of Girard-Perregaux watches. The timepiece symbolises all the expertise associated with Girard-Perregaux timepieces that pushes back the boundaries of watchmaking with grandes complications.

It is one of the few watches to combine mechanical excellence with exceptional musical qualities to such a degree. The Girard-Perregaux 1966 Minute Repeater model pays homage to the most prestigious of Haute Horlogerie traditions. Pure design, noble materials and a beautiful complication: the piece from Girard-Perregaux displays all the signs of an exceptional timepiece.

 

The classic, elegant exterior of this Girard-Perregaux watch houses one of the greatest of grandes complications: the minute repeater. The invention of repeater watches was originally intended to meet the need to strike the hours during the night before the existence of electric lighting. Today, the charm of striking the hours, quarters and minutes makes it one of the best-loved complications for enthusiasts of beautiful watchmaking.

The construction of the Girard-Perregaux 1966 Minute Repeater watch fully respects the great watchmaking tradition. The creation of the sound relies on a device that requires the presence of two circular gongs coiled inside the case and small hammers that strike them at regular intervals. In order to create a vibration to produce the sound that comes closest to perfection, the tuning of the chimes remains one of the most delicate elements; one that Girard-Perregaux takes particular care in refining.

The watch’s special design required thorough research into acoustic qualities. In particular, the Girard-Perregaux worked on three construction points on the case. The diameter of the calibre and the interior diameter of the case are perfectly balanced, a ratio that guarantees maximum resonance. The case-back is curved in order to increase the volume of air between the movement and the case, which significantly improves the propagation of the sound in this Girard-Perregaux watch. Finally, the lower part of the case-back is diamond-polished, an operation that allows acoustic interference to be reduced.
