The watch shows honest signs of age and wear consistent with its production date, while the movement remains functional and the dial retains its vibrant character. Dial and Hands The dial features a captivating deep red sunburst finish that plays beautifully with the light, darkening towards the outer edges. It is adorned with applied gold-tone block indices that add a layer of sophistication and depth. The hands are gold-tone batons with luminous inserts that have aged naturally. At the six o'clock position, the distinctive Advan sun logo is proudly displayed in red and gold. A framed day-date window is positioned at three o'clock, featuring a white background for high legibility. The dial is protected by a faceted crystal which is a signature element of this model, creating interesting distortions and light reflections across the face. Case and Crystal The stainless steel case features a cushion-style design with hidden lugs, typical of the early 1970s aesthetic. The case exhibits visible signs of use, including surface scratches, dings, and marks on the bezel and case flanks, which is expected for a watch of this vintage. The geometry of the case remains defined. The caseback is a screw-down stainless steel type, clearly engraved with the reference number, serial number, and Seiko branding. The faceted crystal shows scratches and wear marks visible under certain lighting angles, consistent with the overall honest condition of the timepiece. Movement Powering this timepiece is the robust Seiko Caliber 6106 automatic movement. This 25-jewel movement is known for its durability and features the innovative "Magic Lever" winding system. Timegrapher readings show approximately -17 to -22 seconds per day which indicates healthy movement function for a watch of this era. The movement appears clean and free of significant corrosion in the images. Strap The watch is fitted with a brown leather strap featuring contrasting yellow stitching. The strap is in very good condition and complements the red tones of the dial and the vintage character of the watch effectively. It secures with a stainless steel buckle. Condition This timepiece is in good vintage condition. The case shows normal vintage wear including scratches and dings, particularly on the polished bezel areas and sides. The dial is well-preserved with no major spotting or damage. The hands and indices show light oxidation consistent with age.

Dimensions The case measures 38 mm in diameter excluding the crown, offering a comfortable and classic fit suitable for a variety of wrist sizes. Remarks This Seiko Advan represents a specific moment in horological history where design boundaries were pushed. The combination of the faceted glass and the red sunburst dial makes it a conversation starter. It is a genuine piece of Japanese domestic history, perfect for collectors who appreciate the eccentric side of Seiko's vintage catalog. History Introduced in the early 1970s, the Seiko Advan line was marketed toward a youthful demographic, emphasizing bold colors, unconventional case shapes, and faceted crystals. It utilized the reliable 6106 and 7019 movements, ensuring that while the exteriors were avant-garde, the internals remained dependable workhorses. These watches are now celebrated for their retro-futuristic appeal and serve as a testament to Seiko's willingness to experiment with design during the quartz crisis era.
