Method for manufacturing watch dials of murrino glass and dials obtained with this method

Abstract

A method for manufacturing a glass watch dial made of "murrino" glass, said method comprising a phase for the axial drilling of the "murrina" disc, the hole resulting therefrom having a diameter to allow the passage of the watch-hand supporting shaft therethrough, one or more honing phases whereby the two surfaces of the "murrina" disc aare made to become parallel to each other, while the disc itself acquires a thickness which is compatible with its use as a watch dial, a phase for trimming of the outer edge of the "murrina" disc and a phase for polishing at least one of the two visible surfaces of the "murrina". The method achieves the manufacturing of watch dials by using "murrinas", i.e., objects constituted by a plurality of small glass cylinders melted together to form desired patterns.
