The hands are baton-style with white inserts for legibility. A framed day and date window is positioned at three o'clock. The dial is viewed through the original faceted crystal, a signature element of the Advan series, which remains in presentable condition with some light signs of age that do not obscure the view. Case and Crystal The stainless steel case features a robust and angular design that is typical of the 1970s "Grammar of Design" era, measuring 38mm in diameter. The case retains its sharp original lines and brushed surfaces, showing only moderate surface wear consistent with a watch of this vintage. The crown is recessed at the four o'clock position, maintaining the sleek and symmetrical silhouette of the watch. The caseback screw-down design is clean with clearly visible engravings including the reference and serial numbers. Movement Powering this watch is the reliable Seiko Caliber 6106C automatic movement. This 25-jewel movement is highly regarded for its durability and features a push-crown quickset function for the day and date. The movement appears clean and well-maintained, offering reliable vintage performance and running within vintage tolerances. Strap The watch is fitted with its original Seiko Advan stainless steel bracelet, featuring the unique cutout link design specific to this model. The clasp is signed with the distinct Advan logo. The bracelet fits a wrist size of approximately 18cm and shows normal stretch and wear consistent with the age of the piece, adding to its authentic character.

Remarks The Seiko Advan series represents a fleeting moment in horological history where experimentation and bold design were paramount. This specific reference, with its gold textured dial and faceted glass, is a quintessential example of 1970s Japanese cool. History Introduced in the early 1970s, the Advan sub-brand was marketed by Seiko as an "advanced" line for the youth market, featuring designs that broke away from traditional dress watch norms. These watches utilized high-grade automatic movements like the 6106, ensuring that while the exteriors were fashion-focused, the internals remained robust and high-quality. Today, the Advan line is celebrated by collectors for its daring aesthetics and historical significance within the JDM landscape. / Second Vintage SKU: SEI-SAJ-0010
