Datograph Perpetual
4 references catalogued.
The Datograph with a perpetual calendar and moonphase added, which is the harder combination it sounds like — a flyback chronograph and a calendar both want the same space under the dial, and the outsize date has to coexist with a date the calendar also tracks. Lange's answer keeps the chronograph's precisely jumping minute counter, so nothing is given up to make room.
