De Bethune brand was founded in 2002 by David Zanetta and the French watchmaker Denis Flageollet.

The watch case is made of 18-carat rose gold, has a diameter of 44 mm and a thickness of 12.5 mm, has hollow lugs and a sapphire case back. The matte silver-plated dial with a central lotus motif is surrounded by a convex ring with dark blue printed Roman numerals. The leaf-shaped hands are made of blued steel, and the spherical moon phase indicator in palladium and flame-blue steel is set on a subdial encrusted with gold stars. The watch is completed with a black leather strap.

De Bethune patented a four-arm titanium balance with platinum weights, a self-compensating free spring hairspring with a flat terminal curve, a double barrel, and a mechanism providing a 5-day power reserve. The watch’s functions include: time display in hours and minutes, a perpetual calendar showing the date at 6 o’clock, the days of the week in the aperture at 9 o’clock, the months in the aperture at 3 o’clock, and the leap year in the aperture at 12 o’clock. A De Bethune spherical moon phase indicator is located at 12 o’clock.
