This perpetual calendar watch, with a pink gold case and smoked dial, has succeeded in apparently simplifying the extreme complexity of its movement.
While the date is displayed in the usual way, the month display is as ingenious as it is discreet with the twelve hour-markers playing a double role representing the 12 months of the year, which are indicated by a short central arrow hand.

As for the leap years, they are discreetly shown on the movement side through the transparent case back.
Hand-wound mechanical in-house HMC 341 calibre.
Hours, minutes, seconds, perpetual calendar, power-reserve indicator.
Pink gold case. Smoked dial.
