Visible through the sapphire caseback, this 275-part movement features a circular-grained mainplate and a 22K gold oscillating weight engraved with a compass rose. It includes a moon phase display at 6 o'clock that tracks the moon's age and requires adjustment only once every 122 years, while the upper dial displays a retrograde date. All functions, including winding, time-setting, and calendar corrections, are managed conveniently via the crown.
