Carl F. Bucherer Manero ChronoPerpetual

 

Limited Edition of 150 Pieces in Stainless Steel and 100 Pieces in 18kt Rose Gold

In the year 46 B.C., Sosigenes, the astronomer from Alexandria, developed the basic principles for the calendar we use today. He divided the year into twelve months: seven months of 31 days, four months of 30 days and one of 29 days, resulting in 365.25 days per year, with one additional day every four years by way of correction. Subsequently, this system became widespread through the entire known world at the time thanks to the Roman Emperor Julius Caesar. However, this so-called “Julian” calendar contained an error of 0.0078 days per year. This discrepancy was corrected in 1582 by Pope Gregory XIII. The system, which is named after him misses out a leap year every 100 years, except in complete centuries where the number of years is divisible by 400. The Gregorian calendar is still used today and forms the basis for the way we measure time.

The functional module which has been specially developed for Carl F. Bucherer by Vaucher also features a precise chronograph with the popular flyback function. A tachymeter scale completes the range of practical functions A Manufacture movement from Vaucher, with contemporary decoration in the distinctive style of the Lucerne watch brand, forms an exclusive basis. In spite of this multiplicity of functions and displays they have ensured optimum readability of the dial on the Manero ChronoPerpetual. This was a challenge which the designers met by making the design as generous as possible, and by incorporating different levels and surface finishes. The chronograph counters for the hours (6 o’clock) and minutes (9 o’clock) as well as the small running seconds hand (12 o’clock) have been clearly integrated into the recessed calendar displays; fine black lines ensure the necessary delimitation between the displays. A narrow hand from the center indicates the stopped seconds. With the wedge-shaped index marks, and the tapering Superluminova-coated hours and minutes-hands, the traditional complication of the perpetual calendar has been reinterpreted. The chronograph hands are in a discreet black. The center of the classical silver-colored dial is matte, while the chronograph counters and the minute division ring are brushed, creating a play of light. The moon phase indication also has a contemporary design, with an anthracite-colored background and a silver-colored moon disk. 

This timeless presentation is expertly continued in the fine rose gold or modern stainless steel case. The case has been subtly reworked for the Manero ChronoPerpetual: Satin finish and polished elements are excitingly contrasted, the lugs are more angular than in earlier models, the bezel has a concave shape while the sapphire crystal is domed, the crown and the polished chronograph push-pieces are elegantly simple. The caseback with integrated sapphire crystal permits a clear view of the mechanical jewel with its 22 kt rose gold oscillating weight.

Specifications:

The case measures 42.5mm x 14.3mm. It has double AR-coated sapphire crystals. It is water resistant to 30 meters.
