The perpetual calendar recognizes the different lengths of the months and knows when the next leap year is imminent, and is thus able to counter the arbitrary features of the Gregorian calendar. No manual correction will be necessary until 2100, when – as in all years that are divisible by 100, but not by 400, – one leap year will be missed out.
The capacities of the Manero ChronoPerpetual are by no means limited to the perpetual calendar with correction-free display of the date at 12 o’clock, the day of the week at 6 o’clock, the month and leap year at 9 o’clock and the moon phase at 3 o’clock. They also feature a precise chronograph with flyback function and a tachymeter scale.
In spite of this multiplicity of functions and displays, the dial of the Manero ChronoPerpetual offers optimum readability, thanks epecially to different levels and surface finishes. With the wedge-shaped index marks, the expressive letters and numbers so characteristic for Carl F. Bucherer, and the tapering Superluminova-coated hours and minutes-hands, the traditional complication of the perpetual calendar has been reinterpreted for our times. The moon phase indication also has a contemporary design, with an anthracite-colored background and a silver-colored moon disk.
The timepiece comes in a 42,5mm fine rose gold or modern stainless steel case, which has been subtly reworked for the Manero ChronoPerpetual: satin finish contrasts with polished elements, the lugs are more angular than in earlier models, the bezel has a concave shape, the sapphire crystal is domed, the crown and chronograph push-pieces are polished. The case back with integrated sapphire crystal permits a clear view of the automatic calibre CFB 1904 with its 22ct rose gold oscillating weight.
The exclusivity of the Manero ChronoPerpetual is enhanced by its strictly limited edition: 150 pieces have been manufactured in stainless steel, while the rose gold versions are limited worldwide to just 100 pieces each.
