The Girard-Perregaux 1966 collection
has been enriched by a new Annual Calendar and Equation of Time model which combines the range’s elegance and purity of line with the originality of a
ruthenium dial.
In 1966 Girard-Perregaux received the Neuchâtel Observatory’s Centenary Prize in recognition of its developments in the field of research and precision. The Girard-Perregaux line was thought to pay homage to the brand’s innovative spirit and achievements.
The annual calendar presenting the date and month automatically takes the length of the month into account, requiring only the occasional correction every 28th February of non-leap years. With its hand at 4.30, the equation of time indicates the difference between the real solar time and the mean or civil time. The length of a solar day actually varies daily due to the elliptical shape of the Earth’s orbit. This astronomical complication is based on an ingenious mechanism incorporating an annual disc with an elliptical cam that reproduces the Earth’s movement around the Sun.
Taking technical sophistication even further, corrections to the calendar are made with the crown, in both directions. The system is simple to use and the absence of a corrector on the case leaves the purity of its harmonious curves intact.
The ruthenium-adorned dial was designed to offer an original, harmonious display. Delicately sunray-brushed, it is enhanced by baton-type applied hour markers and fine leaf-shaped hands that add to its clarity. The counters with their precise markings increase the readability of the functions. The curved case is 40 mm in diameter and its profile presents a remarkable silhouette.
The open case-back reveals the movement and its oscillating weight.
The movement, the GP033M0, is composed of 287 parts and was entirely developed and produced by the Girard-Perregaux Manufacture.
