Two grand complications brought together: the Lange 1 Tourbillon Perpetual Calendar with its "asymmetrical" appeal places the calendar indications in a clearly legible position on the outer part of the dial, with the hours and minutes displayed at 3 o'clock and the large date at 11 o'clock. Only a small inscription at 12 o'clock reminds us of the tourbillon with its patented seconds stop device, which is displayed on the caseback side. The perpetual calendar requires a manual correction only on 1 March of the year 2100, while for the moon phase display, a correction of one day is only necessary every 122 years. The movement is the automatic L.0821 calibre. It is made of pink gold. Price: 240,000 euros.
