This ingenious mechanism is programmed to take account of the varying lengths of each month from March 1st to the end of February in the following year. This is the first automatic wristwatch in which the calendar needs to be adjusted only once a year.A similar watch is published in "Patek Philippe Wristwatches", by Martin Huber and Aan Banbery, 1998 Edition, p. 323.
