Brazilian aviator Alberto Santos-Dumont changed the course of modern timekeeping when he tasked Louis Cartier with designing a wearable alternative to a pocket watch that he could rely on mid-flight. Defined by the iconic square shape, this extra-large model has a satin-finish sunray-effect dial framed by a layered 18-karat gold and stainless steel case complete with signature exposed screws. A blue cabochon crown nods to the Maison's storied heritage.For warranty information, please refer to details & care
