Having seen all sorts of watches whilst browsing Seiko I came across some very fancy ones displaying paintings on the dials and I got interested in the origin and meaning of these. There is very little information online but I managed to find out that these watches are mostly from the 70's and they are actually mod's (modified watches) made back then. On these watches only the dial has been modified though and they display various motifs from the Ukiyo-e artform that was prevalent during the Japanese Edo era.
