The new Jaquet Droz Tourbillon Skelet Sapphire Opal ref. J0135270091 is a unique piece with a sapphire crystal case that bathes a translucent opal dial. Vibrant and radiant, this 42 mm piece, paired with a pristinely white strap, changes appearance with the light. Draped in sapphire, beneath a veil of opal, the piece subtly allows some of its usually hidden mechanism to be glimpsed. Its skeleton movement suspended in space is powered by an automatic self-winding movement with a flying tourbillon and an outstanding power reserve of eight days.
