Frederique Constant refines its iconic Classics Heart Beat Moonphase Date design

Frederique Constant’s Classics Heart Beat Moonphase Date, which was first released eight years ago, is back in a new edition that is both classic in spirit and contemporary in execution. Its 40 mm stainless steel case houses a deep blue dial, giving pride of place to the emblematic Heart Beat aperture. A Maison signature, it offers a view of the balance wheel at 12 o’clock, which powers the self-winding FC-335 mechanical calibre.

The Classics Heart Beat Moonphase Date is the embodiment of one of Frederique Constant’s most iconic designs. The piece was designed to transcend styles, trends and decades—a mission carried out successfully, particularly thanks to its aperture at 12 o’clock, known as the Heart Beat, a testament to the aesthetic mark Frederique Constant has made on the noble watchmaking tradition.

Frederique Constant’s latest timepiece showcases perfect balance in both function and form. At 12 o’clock lies the iconic “Heart Beat” aperture—an emblem of the brand’s watchmaking legacy for nearly 30 years—revealing the escapement of the self-winding FC-335 mechanical movement, beating at 28,800 vibrations per hour. In true Frederique Constant fashion, the watch is engineered for simplicity: all functions—winding, hours, minutes, date, and moon phase—are adjusted using a single crown. The positions are intuitive, with special care advised to set the moon phase at 10:10 to preserve the mechanism.

In elegant symmetry, the moon phase rests at 6 o’clock—a once-feminine complication now universally admired for its cosmic charm. A nod to horology’s astronomical roots, this 29.5-day cycle connects fleeting seconds with sidereal time, Earth with cosmos. Set against a rich blue backdrop, the design draws inspiration from 19th-century flame-blued finishes and features a “Clou de Paris” guilloche—a centuries-old motif that reflects light beautifully, adding depth and timeless allure to the dial.

At the centre of the dial are four hands. The first two, the hours and minutes, end in a so-called “hollowed apple” motif—in Breguet style—, a subtle historical nod to the traditional aesthetic canons of early watchmaking. The next, the seconds—long and slim—keeps the time of the self-winding FC-335 movement with a 38-hour power reserve, visible through the sapphire caseback. The final hand, standing out with its arrow motif, points towards the date, shown in a circle on the flange. It is all worn on a blue leather bracelet, with white topstitching and a steel pin buckle.
