Antoine Preziuso is a watchmaker belonging to the Swiss independent watchmaker academy. He handles his own brands and also gets requests from Breguet, Harry Winston and others to make super-complicated watches. He used to have 17 staffs at the time, but now he manufactures watches alone at a studio in the outskirts of Geneva (still cooperating with craftsmans etc). In 2015 he announced the Triple Tourbillon, which he collaborated with his son Florian for the Basel Fair.
