De Bethune: De Bethune DB25 QP Perpetual Calendar
De Bethune's perpetual calendar brings poetic beauty to the finest mechanics.
De Bethune has built on the Manufacture's research and technology to develop for this timepiece the DB 2324 QP automatic calibre. It incorporates a perpetual calendar, spherical moon phases with a precision of one day in 122 years, a self-regulating twin barrel, a triple pare-chute shock-absorbing system, and a titanium-platinum balance wheel.
An avant-garde mechanism that is poetry in motion.
