Now available at auction from Second Vintage This is a quintessential example of Seiko's daring 1970s design philosophy, capturing the vibrant energy of the Japanese Domestic Market during the golden era of watchmaking. The Seiko Advan series was created to appeal to a younger, style-conscious generation, and this specific reference stands out with its incredible textured dial and faceted crystal. With a distinct case geometry and a hypnotic blue vortex dial pattern, this timepiece is not just a watch but a piece of wearable kinetic art that commands attention on the wrist. Brand: Seiko Model: Advan Reference Number: 6106-7670 Serial Number: 340075 Movement: Seiko Automatic Caliber 6106C Dial: Textured blue vortex with applied indices and Advan logo Case Size: 38 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1973 Condition: Good vintage condition. The watch shows honest signs of age and wear consistent with a piece from the early 1970s, particularly on the faceted crystal. Timegrapher testing shows the movement running between +40 and +45 seconds per day, indicating a running movement within acceptable parameters for an unserviced vintage piece. Dial and Hands The dial is the absolute highlight of this timepiece, featuring a mesmerizing deep blue hue with a concentric swirl or vortex texture that catches the light beautifully. It is adorned with the applied "sun" Advan logo in red and gold at the six o'clock position and features chunky, multi-faceted applied hour markers that reflect the 1970s aesthetic. A day-date window is positioned at three o'clock, featuring both Kanji and English days, confirming its JDM heritage. The hands are original batons with luminous inserts, showing visible signs of aging and patina consistent with the age of the watch. Case and Crystal The stainless steel case features a distinct semi-tonneau shape with hidden lugs, giving it a streamlined and integrated appearance. The case lines remain relatively sharp, though there are visible surface scratches and contact marks throughout, consistent with a life of honest wear. The watch is fitted with its original faceted cut glass crystal, a signature of the Advan line. The crystal shows noticeable scratches and chipping along the faceted edges, which is common for these elevated geometric crystals, yet it does not obscure the visibility of the stunning dial beneath. Movement Powering this timepiece is the robust and highly regarded Seiko Caliber 6106C automatic movement. Known for its durability and engineering quality, this 23-jewel movement features a hacking seconds function and a quickset date mechanism by pushing the crown. The movement presents cleanly in photographs and offers reliable vintage performance. Strap The watch comes fitted on a stainless steel link bracelet that complements the case design. The bracelet is comfortable and retains its period-correct aesthetic. It is sized to fit a wrist of approximately 19 cm. Condition This timepiece is in good vintage condition. It is an honest survivor that has been worn and enjoyed. The most notable wear is present on the faceted crystal and the hands, which show oxidation. The dial itself remains in excellent condition with no major blemishes to the textured surface. The case retains its architectural integrity despite surface wear. Dimensions The case measures 38 mm in diameter excluding the crown, making it a very wearable size for modern standards while retaining its vintage charm. The wrist presence is enhanced by the thick faceted crystal and the integrated bracelet design. Remarks This Seiko Advan is a fantastic collector's piece for those who appreciate the avant-garde designs of the 1970s. The combination of the "whirlpool" dial texture and the faceted glass makes it a visually dynamic watch that changes character depending on the lighting. It is a rare opportunity to own a distinct piece of JDM history. History Introduced in the early 1970s, the Seiko Advan line was marketed as a premium, fashion-forward collection targeting the "mod" culture and the youth of Japan. These watches were characterized by their bold use of color, faceted crystals, and unconventional case shapes. The Advan series represents a time when Seiko was experimenting heavily with design, resulting in some of the most memorable and collectible vintage watches available today. / Second Vintage SKU: SEI-SAX-0019
