The Shippo enamel dials, crafted especially for these Presage limited editions add further depth to the Presage collection by blending Japanese aesthetics, traditional craftsmanship and Seiko’s skill in mechanical watchmaking. Shippo is a particular type of enamel that was developed in Japan in the 17th century. Shippo is distinguished from porcelain enamel by its transparency and in the way it is polished after firing – a process that is particularly challenging on a watch dial that is no more than 1mm thick.
