Speake-Marin Minute Repeater Flying Tourbillon "Légèreté"

The new Speake-Marin Haute Horlogerie masterpiece is called “Légèreté”, which means “Lightness” in English, to highlight the sapphire-crystal case, which allows to literally dive into the movement from the top, the sides or the case back. The case is made up of three parts: the bezel, the case back and the middle section. The process by which the sapphire is made into a finished watch case is extraordinarily difficult, involving many hours of machining and polishing. The most difficult part is the case finishing where one must avoid any scratches during manufacture: the case must be perfectly transparent.
