The DD 4900 is an advanced chronograph module with grande date (two date discs at 12:00) and a 4-year calendar with month display at 4:30. This sophisticated complication was notably used by TAG Heuer in their Carrera MP4-12C. The 4-year calendar only requires adjustment at the end of February, making it nearly a perpetual calendar.
