Its main difference from porcelain enamel lies in the way it is polished after firing, a process that is particularly challenging on a watch dial that is no more than 1 mm high. The Presage Shippo enamel dial is made by Ando Cloisonne, a specialist manufacturer in Nagoya with over 100 years of history. Craftsman Wataru Totani paints the glaze by hand onto the surface of the dial. To ensure that the dials comply with Seiko’s high ecological and safety standards as well as the EU’s RoHS Directive, he uses a lead-free glaze specially developed for these watches. The dial is then fired at 800 degrees Celsius. The painting and firing processes are repeated several times to ensure the evenness of the enamel. Only when Totani is completely satisfied is the dial polished so that the delicate pattern emerges and a perfect, smooth surface is achieved.
