Remarks This Seiko Advan represents a specific moment in time when watch design broke free from tradition to embrace color and geometry. It is a fantastic example of JDM (Japanese Domestic Market) styling that has found a global following among collectors who appreciate the funkier side of the 1970s. History Introduced in the early 1970s, the Advan sub-brand was marketed towards a younger, style-conscious generation in Japan. Utilizing the reliable 6106 base calibers, Seiko created a line that prioritized avant-garde design, featuring faceted crystals and colorful dials that set them apart from the conservative dress watches of the previous decade. Today, these watches are celebrated for their unique aesthetic and their representation of 1970s pop culture influence on industrial design. / Second Vintage SKU: SEI1XOG175000
