It uses the Caliber L086.8 automatic movement with a 72 hour power reserve, 21.6k bph frequency, 40 jewels and a big date complication visible at the 12 o’clock.
According to A. Lange – “Since the re-establishment of the A. Lange & Söhne manufactory and presentation of its first new collection in 1994, there has been one complication that persistently characterises the design of many of our timepieces: the patented A. Lange & Söhne outsize date, which enables a date display with digits around three times as large as those in watches of comparable dimensions. “
