Anyone who wears a mechanical watch with a date display will be familiar with the problems caused by months of differing lengths, particularly in leap years. Because simple, standard calendar mechanisms always switch from the 30th to the 31st, the date has to be moved forward manually to the first after months with fewer days.

A perpetual calendar mechanism, however, is able to correctly handle these transitions independently, even factoring in leap years. The complexity of this mechanism demands the ultimate in watchmaking craftsmanship, and is appropriately referred to as the “grand complication”. Manual correction will not be necessary until the year 2100, when – as in all years divisible by 100, but not by 400 – one leap year will be skipped.

For all lovers of this traditional masterpiece of the watchmaker’s art, Carl F. Bucherer now presents a limited edition of the Manero ChronoPerpetual featuring a unique combination of chronograph and perpetual calendar. The Manero ChronoPerpetual offers a perpetual calendar date display at 12 o’clock, day of the week at 6 o’clock, month and leap year at 9 o’clock, and moon phase at 3 o’clock – all of which do not require correction.

The functional module specially developed for Carl F. Bucherer also features a precision chronograph with the popular flyback function. A tachymeter scale on the bezel completes the range of practical functionalities for which Carl F. Bucherer is famous. A movement from Vaucher Manufacture, which features a contemporary design in the distinctive style of the Lucerne watch brand, forms an exclusive basis.

Despite this multiplicity of functions and displays, Carl F. Bucherer has ensured optimum readability of the dial on the Manero ChronoPerpetual Limited Edition. The designers met this challenge by giving it generous dimensions, different levels, and various surface finishes.
The chronograph counters for the hours (6 o’clock), minutes (9 o’clock), and small running seconds hand (12 o’clock) are distinctively and attractively integrated into the striking recessed calendar displays, while fine lines provide the necessary readability and the slender stopwatch hand in the center marks counted seconds.
