For the first time, a regulator with moon phases. The mechanical movement has been developed on an old calibre (P. 7046) that has been out of use for 30 years. Decorated and set with blued screws, it is visible through the transparent case back. The original dial with a regulator design (hours at 12 o’clock, centre minutes and small seconds at 6 o’clock) also features a date hand and a moon-phase indicator at 9 o’clock.
