De Bethune DB25 Perpetual Calendar with a Green Dial

The Manufacture De Bethune is enriching its collection of classic watches with a state-of-the-art interpretation of the perpetual calendar.

The De Bethune perpetual calendar is tinged with poetry and combines the finesse of watchmaking with the precision mechanics of the Manufacture by bringing together moon phase, starry sky and perpetual calendar in an exceptional timepiece. Inspired by the drum, the round case with a diameter of 44 mm, with its fine and resolutely classic lines, is subtly enhanced by the hollowed-out horns characteristic of the DB25 collection.

A poetic timepiece

The finesse of the decorations and the purity of the green hand-guilloche dial, radiating in 12 sectors, underline the legibility of the dial, which is built up by the assembly of ring-shaped appliques delimiting the sub-dials and the hour circle. At 12 o'clock, a sphere in palladium and black oxidized zirconium sits in a sky set with gold stars, also incorporating a leap year indicator in a gold pastille in the starry sky at 12 o'clock. The date can be read on a dial located at 6 o'clock, while the windows indicating the day of the week and the month are located at 9 and 3 o'clock respectively.

Unparalleled comfort

The round case of the new DB25QP retains the harmonious lines that contributed to the success of the original DB25QP but is offered for the first time in titanium. This further enhances the practicality and comfort of this timepiece.

A refined movement

Developed in the Manufacture's Haute Horlogerie workshops in Sainte Croix in the Swiss Jura, the automatic DB2324 caliber benefits from De Bethune's research and technology know-how, including a perpetual calendar, a spherical moon indicating the moon phases with a precision of 1 day/122 years, a self-regulating double barrel, a triple pare-chute system and a titanium/grey gold balance.

A sapphire caseback allows one to admire the complexity of the movement as well as the refinement of its finishing: ¾ platinum bridge with star decoration, sandblasted and hand-colored, blued titanium balance bridge and oscillating weight arm, hand-colored white gold weight, hand-beveled and mirror-polished steels.

New reference

This new perpetual calendar comes with a green textile strap with a polished titanium buckle and pin. A second leather strap accompanies it. A perfect illustration of the technical and aesthetic know-how of the Manufacture, this new reference DB25QPATIS4 is destined to replace all the DB25QPs previously presented in the current De Bethune collection.
