The Arceau, designed by Henri d'Origny, celebrates its 35th anniversary and presents a new moon-phase complication in an elegant 38-millimetre model that is also suitable for women's wrists. The collection comes in two variants, with a white mother-of-pearl dial with iridescent reflections or a black dial. The hours are elegantly marked out in a sequence of slanted Arabic numerals, whose handwriting is faithful to that of the original model. The moon phases, on a blue background and rhodium-plated decoration, are positioned between 10 and 11 o'clock. The Arceau Petite Lune has a steel case and is equipped with a self-winding mechanical movement with a Dubois Dépraz moon phase module and 42-hour power reserve.
