Available now on auction by Second Vintage The 1970s marked a period of boundless creativity for Seiko, perfectly encapsulated by the Advan collection. Short for "Advanced," the Advan line was aimed squarely at a youthful, fashion-forward demographic, resulting in some of the most daring and architecturally fascinating watches of the era. This particular example is a masterclass in retro-futuristic design, featuring a highly unconventional asymmetrical case, a complex multi-textured dial with towering indices, and a dramatic faceted crystal that fractures light into a mesmerizing display. It is a bold, unapologetic statement piece that captures the vibrant spirit of Japanese watchmaking in the seventies. Brand: Seiko Model: Advan Reference Number: 6106-7570 Serial Number: 233150 Movement: Automatic Caliber 6106C, 25 Jewels Dial: Gold and olive sunburst center with a textured outer track, monumental architectural applied indices, day-date aperture, and red Advan sun logo; dial shows significant wear. Case Size: 39 mm Case Material: Stainless Steel Production Year: 1972 Condition: Honest vintage condition, with pronounced dial wear and clear case wear complemented by a dramatic faceted crystal. Dial and Hands The dial of this Advan features a dynamic landscape of textures and levels, with its radiating sunburst finish shifting between warm gold and olive tones. The unique design includes a distinctly brushed, textured outer chapter ring and monumental, stepped applied indices reminiscent of a brutalist cityscape. The applied Seiko logo is balanced beneath twelve o'clock, with the vibrant red Advan sun emblem and stylized text below. A framed day-date complication is positioned at three o'clock. The handset is comprised of polished, flat-profile baton hands with white center stripes for legibility, along with a slender sweeping seconds hand. Notably, the dial reveals prominent wear across its surface, with visible fading, patina, and marks that attest to decades of use, firmly distinguishing this as a watch with genuine vintage character. Case and Crystal The stainless steel case boasts a highly unconventional, shield-like asymmetrical silhouette that defies traditional watchmaking geometry. It features brushed flat upper surfaces that transition sharply into polished, sloping flanks. A recessed crown is cleanly integrated into the case side at the four o'clock position, maintaining the uninterrupted flow of the case lines. Sitting above the dial is a spectacular faceted mineral crystal, featuring a profound diagonal cut across the upper section that creates a split, prismatic reflection, adding immense depth to the viewing experience. The case displays honest surface scratches, light scuffs, and handling marks, but retains its fundamental factory architecture without heavy polishing. The solid screw-down caseback is crisply engraved with the Suwa Seikosha logo, reference numbers, and serial data. Movement Powering this distinctive timepiece is the Seiko automatic Caliber 6106C, clearly marked on the mainplate in the provided close-up images. The rotor is cleanly stamped with the Seiko branding and denotes its 25-jewel construction. The movement presents well visually, with typical signs of vintage age on the surrounding casing ring. Timegrapher results reflect current performance at -20 to -27 seconds per day. Running and operational, offering reliable vintage performance. Strap The watch is fitted with a period correct black leather strap featuring contrasting white stitching at the lugs and a stainless steel pin buckle, complementing the bold aesthetic of the case and dial. Condition This Seiko Advan is offered in honest vintage condition, with pronounced case wear and a notably worn dial revealing extensive signs of age, including fading and patina. Despite the wear, the multi-level architecture and indices remain visually impactful under the dramatic faceted crystal. The movement functions steadily, making this a wearable and characterful vintage piece for those who appreciate true survivor watches. Dimensions 39 mm case diameter. Remarks The Seiko Advan series represents a uniquely adventurous chapter in the brand's history, and references featuring this level of dial complexity and crystal faceting are highly prized by collectors of vintage Japanese horology. Its commanding wrist presence and undeniable retro charm make it a standout addition to any collection focused on seventies design. History Introduced in the early 1970s, the Seiko Advan line was a deliberate departure from the conservative styling of the Grand Seiko and King Seiko ranges. Designed to appeal to a younger, trend-conscious audience in Japan, Advan watches embraced the psychedelic and space-age aesthetics of the era. They became renowned for their brightly colored dials, asymmetrical cases, and deeply faceted crystals. Today, they serve as vibrant time capsules of a creatively uninhibited era in watch design, celebrated for their daring execution and reliable in-house mechanicals.
