This refers to Henri Jacot-Burmann’s patented calendar design. It displays the date, day of the week and the month.

The movement is a good quality swiss lever example, with thin construction. It has a cut compensated balance. It is unique, with the modification for the calendar function. The movement has recently been serviced and is keeping accurate time.
