Breguet Classique Tourbillon et quantième perpétuel squelette

Created in platinum, the stunning skeleton watch features a tourbillion and a perpetual calendar. The fruit of much labour, the timepiece features an off-centre chapter ring, an arc displaying the date of the moon with a jumping retrograde mechanism, and two sub- dials for the days and months. The perpetual calendar mechanism, with leap-year indicator, is at 3 o'clock and the tourbillion cage with seconds on its shaft is positioned at 6 o'clock. The hand-wound movement houses 21 jewels and is engraved entirely by hand.
