Remarks The Seiko Advan series was marketed towards a younger, style-conscious generation in Japan during the 1970s, resulting in some of the most creative designs in Seiko's back catalog. This specific reference 6106-7680 captures that spirit perfectly with its intricate dial and cut glass. It is a fantastic conversation piece for enthusiasts of Japanese design. History Introduced in the early 1970s, the Advan line was a sub-brand of Seiko designed to showcase "advanced" styling. These watches were strictly for the Japanese Domestic Market (JDM) and utilized high-grade automatic movements like the 6106 and 7019. They are characterized by their colorful dials, faceted crystals, and the signature sun logo, marking a period where Seiko experimented heavily with avant-garde aesthetics. / Second Vintage SKU: SEIOCUE2U0000
