The Bovet Retrograde Perpetual Calendar Récital 21 has an atypical perpetual calendar display and features the brand’s “writing slope” case. Aside from the perpetual calendar in the Grand Récital tourbillon, this complication is being introduced in the Dimier Collection for the first time.

This is an atypical perpetual calendar display

The handiwork of brand owner Pascal Raffy, the “writing slope” case features a bezel inclined at 6 o’clock. This architecture helps Bovet play with various types of displays by using domes, rollers, discs, and three-dimensional hands. Inspired by his grandfather’s writing desk, this inclined case construction was a hallmark of the Astronomy trilogy, which featured the Aiguille d’Or Grand Prix-winning Grand Récital 22 timepiece.

The inclined case is 44.4 mm wide and 15.5 mm thick and is available in titanium or 18K red gold. The watch offers a completely different take on the classical style codes of a perpetual calendar. The minute and hour hands are located in the center on Bovet’s now characteristic circular-brushed blue dial. The dial is first circular brushed and then colored before eight layers of lacquer are applied to it. These are then polished to provide the luster and depth. Thanks to the inclined case, the dial-makers have plenty of volume to play with and consequently the seconds hand sweeps under the hours and minutes dial.

The small seconds hand sweeps under the blue dial

The space around the dial is rhodium-plated it features circular Geneva stripes and buyers can choose between a circular “Côtes de Genève” motif or the “Fleurisanne” motif hand-engraved by the Maison’s engravers. The days of the month are displayed by a retrograde index that rotates around the hours and minutes while the days and months appear in vertical apertures at 12 o’clock and 6 respectively.

The leap year cycle is displayed in a circular aperture at 3 o’clock and a seconds hand is placed at 9 o’clock bringing a sense of balance to the dial. For improved reliability and longevity, the watchmakers developed a mechanism that slows down the indicator during its retrograde jump.

Notice the asymmetric flange that frames the caseback

The caseback reveals an asymmetric flange that frames the movement. A patented double coaxial seconds mechanism, as well as the power reserve indicator is visible here. When fully wound, the movement supplies five days power from a single barrel. Though there are correctors to adjust the perpetual calendar’s indications, Bovet’s engineers have included an ingenious system that streamlines adjustments. There are dedicated correctors for the days, date, and month functions-simultaneously.

So, if a user wishes to adjust their timekeeper after it has been stopped for several days, they simply have to activate this unique corrector until the correct date is shown. Adjusting all the functions of the Récital 21 are thus fully synchronized. The hand-finished movement has been executed to the levels of quality that you expect from a Bovet movement. This watch is priced at CHF72,000 (without taxes).
