Four push-piece correctors set the perpetual calendar; the corrector at 9 o'clock sets "days of the week only, the " corrector at 11:30 sets "date and days of the week," the corrector at 12:30 sets "month," and the corrector at 6 o'clock sets "moon phase."

It features a temperature-adjustable monometallic Gyromax balance with five positions, a self-compensating Spiromax balance spring, an index regulator, and a 22k gold off-center micro-rotor.
