The RGM Model 501-PC Perpetual Calendar is a watch we have wanted to make for many years.
It marks an important return for RGM, being our first perpetual calendar since the Model 103-R Minute Repeater Perpetual of the late 1990s. For me, bringing a perpetual calendar back into the RGM collection has always been something I wanted to accomplish. It is a complicated and demanding form of watchmaking, but it is also one that represents so much of what I value about traditional horology.
The design is unmistakably RGM—classical in character, restrained in its proportions, and rooted in the traditions of watchmaking. The fired enamel dial is inspired by perpetual calendar pocket watches from the late 1890s, a period when complicated watches were made with a wonderful combination of technical ingenuity and elegance.
