The UNDONE Nippon Erotica: Shunga Collection offers a modern reinterpretation of the erotic watch design that was a hallmark of high society in the 17th century. The front of the Shunga: Edo watch displays only the upper bodies of figures, invoking a sense of mystery and leaving much to the imagination. Turning the piece over reveals the watch’s “practical” side: an intricately detailed scene of a couple engaged in coitus, visible through a patterned glass case back. This hidden artwork adds a layer of intrigue to the timepiece. The dial features “當世風俗通” (the Ukiyo custom of pleasure-seeking) elegantly positioned below the 12 o’clock mark, while “春” (Shunga), meaning the picture of spring—a poetic euphemism for sex—is visible on the chronograph counter at 9:00. Designed with a vintage look, the watch is paired with a brown strap that perfectly complements the dial. The UNDONE Shunga: Edo is a limited edition, with only 300 pieces available, each uniquely serialized to emphasize its exclusivity and uniqueness. This collection not only celebrates the rich heritage of Shunga art but also brings it into the modern era with elegance and style.
