Patrimony retrograde day-date

An unprecedented “majestic blue” colour for Patrimony Patrimony retrograde day-date, self-winding Calibre 2460 R31R7/2 As original as it is technically complicated, the double retrograde display of the Patrimony retrograde day-date is a delight to observe during the transition from the 31st of one month to the 1st of the next, or from Sunday to Monday. At 42.5 mm in diameter and just 9.7mm thick, this horological wonder bears the imprint of the talented watchmakers within the Manufacture who have so skilfully preserved the pleasing proportions of the Patrimony collection.
