2460 R31R7/3 description
Minutes, retrograde hand-type day of the week, stop seconds device, retrograde hand-type date, Hours
The Patrimony retrograde day-date is driven by in-house self-winding calibre 2460 R31R7/3 operating at a rate of 28,800 vibrations per hour. It is fitted with a 22K gold openworked oscillating weight with a design inspired by the Maltese cross emblem and has an approximately 40-hour power reserve. In the grand tradition of in-house calibres, the bridges are finished with hand-polished angles. Straight-graining, which consists of perfectly smoothing the component flanks, is also performed by hand, while the screws are meticulously polished. The mainplate is circular-grained on both sides, while the bridges are adorned on the back with the Côtes de Genève motif.
