A quietly idiosyncratic perpetual calendar, this Endeavour captures H. Moser and Cie's talent for making serious watchmaking feel remarkably pared back. The 40.8mm white gold case and silver dial give it a cool, restrained presence that suits the line's clean architecture. Beneath that calm exterior is a manual-wind movement with perpetual calendar and date. At 11.1mm thick, it wears with the balanced proportions collectors expect from a complicated dress watch.
