Abstract
A method for producing metal decorations on a curved dial made of insulating material includes forming, by a method of the LIGA-UV type, a mould made of photosensitive resin and of galvanically depositing a layer of at least one metal from the conductive layer in order to form a block substantially reaching the upper surface of the photosensitive resin.
