Brand: Seiko Model: Advan Reference Number: 6106-7570 Serial Number: 364244 Movement: Automatic, Caliber 6106C, 25 Jewels Dial: Teal sunburst with gold-toned chapter ring, applied logos, showing visible patina and oxidation on the hands Case Size: 38 mm (excluding the crown) Case Material: Stainless Steel Production Date: June 1973 Condition: Good vintage condition with honest wear and a striking dial presence Dial and Hands The dial is the undeniable focal point of this timepiece, featuring a vibrant teal sunburst finish that radiates from the center, beautifully contrasted by a broad, stepped gold-toned chapter ring. The typography is crisp, with the printed advan text complementing the applied Seiko logo and the signature applied Advan sun emblem. The faceted block indices add significant depth to the display, alongside a framed day-date aperture positioned at three o'clock. Carefully assessing the condition, the dial surface itself remains well-preserved and visually striking, maintaining its original luster. However, the original baton hands exhibit noticeable surface aging, oxidation, and spotting, presenting a clear, age-consistent patina that speaks to the vintage nature of the watch. Case and Crystal The stainless steel case features a distinctive, angular geometry characteristic of the Advan series, with a seamlessly integrated recessed crown located at the four o'clock position. The case displays honest signs of wear, including surface scratches, scuffs, and softened edges along the polished flanks and faceted lugs, indicative of regular use over the decades. The transition between the case surfaces retains the fundamental architectural spirit of the original design. The screw-down caseback is clearly engraved with the reference and serial numbers, alongside the Seiko medallion text. The watch is fitted with its characteristic faceted Hardlex crystal, adding dimensionality to the dial presentation; it shows minor signs of wear but provides a clear, unobstructed view of the vibrant display beneath. Movement Powering this watch is the Seiko caliber 6106C, a robust 25-jewel automatic movement. The movement components, including the rotor and bridges, are clearly stamped with the caliber designation, jewel count, and Seiko branding. The visual inspection of the open caseback shots reveals a clean and well-maintained mechanism, reflecting Seiko's enduring engineering standards and the reliable mechanical heart typical of their 1970s production. Strap The watch is fitted with a handsome black leather strap featuring contrasting white vintage-style stitching and a polished stainless steel pin buckle, comfortably complementing the bold aesthetic and substantial presence of the case. Condition Good vintage condition. The watch presents a highly attractive and bold appearance, with a beautifully preserved dial color that immediately draws the eye. The case shows normal, honest wear with surface marks and scuffs consistent with its age. The hands display distinct visible patina and oxidation, while the dial remains remarkably clean. Overall, it remains a structurally sound and visually compelling example of 1970s Seiko design. Dimensions The stainless steel case measures a substantial 38 mm in diameter, excluding the recessed crown, providing a prominent and era-accurate stance on the wrist that wears comfortably thanks to the integrated lug design.
