Streamliner Tourbillon Concept CeramicThis absorbing material only enhances the fluid lines of the Streamliner. The watchs cushion shaped case and integrated bracelet are cast in a deep anthracite gray ceramic, offering a sumptuous contrast to the fire kissed Red fum Grand Feu enamel dial. This is a timepiece that burns with intensity. The flying tourbillon at six oclock, equipped with our signature double hairspring, completes one of our most radical watches yet.
