A framed day-date window is positioned at 3 o'clock, featuring the desirable Kanji and English day wheel, a signature of JDM models. The dial is protected by the original faceted "cut glass" crystal, which creates unique light distortions and adds significant depth to the watch face. Case and Crystal The stainless steel case measures 36mm and features a classic C-shape cushion design with a recessed crown at the 4 o'clock position, creating a streamlined silhouette. The case retains good definition on its curves and edges, though it shows surface scratches and marks typical of a watch worn and enjoyed over decades. The faceted mineral crystal is a standout feature, though it exhibits visible scratches and wear along the faceted edges, which is common for this specific crystal type. The screw-down caseback is clearly engraved with the reference and serial numbers. Movement Powering the watch is the robust Seiko Caliber 6106C automatic movement. This 23-jewel movement features the "SS" or Second Stop hacking capability, allowing for precise time setting. The movement appears clean and visually well-maintained, offering reliable vintage performance and running within vintage tolerances. Strap The watch is fitted with a stainless steel link bracelet that complements the case design perfectly. It features a signed Seiko 5 Actus folding clasp. The bracelet is currently sized to fit a wrist of approximately 19cm. A vintage calendar sticker from 1982 is adhered to the clasp, a charming artifact added by a previous owner that adds to the unique history of the piece. Condition This timepiece is in good vintage condition. While there are visible signs of wear throughout the case and bracelet, including surface scratches, the watch remains structurally sound and attractive. The faceted crystal shows wear and scratches, but the dial underneath remains in excellent condition. The movement is functioning correctly, and the day-date quickset mechanism operates as intended. Dimensions The case measures 36mm in diameter excluding the crown. The lug width accommodates the bracelet comfortably, and the watch sits with a balanced presence suitable for various wrist sizes. Remarks The Seiko 5 Actus SS series represents a golden era of affordable luxury from the Suwa Seikosha factory.

The combination of the faceted crystal, orange dial accents, and Kanji date wheel makes this a quintessential example of 1970s watchmaking culture. History Introduced in the late 1960s and produced through the 1970s, the Seiko Actus line was targeted at Japan's young professionals who desired a watch that was both stylish and technologically advanced. The "SS" designation was a significant selling point, highlighting the hacking seconds hand which was a premium feature at the time. These watches have since garnered a cult following for their durability and their bold, retro-futuristic designs. / Second Vintage SKU: SEI-SAS-0001
