RGM Unveils Perpetual Calendar Model 501‑PC
The RGM Perpetual Calendar Model 501‑PC marks the American independent watchmaker’s return to the complex perpetual calendar complication after decades, combining a 39 mm stainless‑steel case with a white Grand Feu enamel dial and classic Roman numerals. Powered by a heavily modified ETA 2892‑A2 movement with a custom Dubois Dépraz calendar module, the watch features a moon‑phase display, day, date and month indicators, and a solid‑gold winding rotor, all finished with traditional Côtes de Genève, perlage and blued screws visible through a sapphire‑backed case. Priced at USD 39,900, it is offered on a brown alligator strap and showcases RGM’s dedication to American watchmaking heritage and technical mastery. The design draws inspiration from late‑1800s pocket watches, employing brushed and polished steel, curved lugs, and a raised box‑style sapphire crystal that enhances visual depth. The dial’s white enamel backdrop highlights the blued steel hands and red Arabic numerals on the minute track, while the month display uses crosshairs and color cues for leap years. With a 50 m water resistance, 28,800 vph frequency, and a power reserve of 52–56 hours, the 501‑PC delivers both aesthetic elegance and functional precision, reinforcing RGM’s reputation among collectors and enthusiasts.
