It is adorned with applied silver-tone block indices and matching baton hands with luminous inlays.

The applied Seiko and 5 Actus SS logos remain crisp and elevated above the dial surface. The dial is in excellent condition with no significant aging or blemishes. Case and Crystal The stainless steel case measures 37 mm and features the characteristic sharp geometry of the 1970s with a recessed crown at the four o'clock position. The defining feature of this reference is the original faceted mineral glass crystal, which features multiple geometric cuts that catch the light and create a prism effect over the dial. The case shows visible scratches and signs of wear consistent with its age, retaining its original lines without over-polishing. Movement Powering this timepiece is the robust Seiko caliber 6106C automatic movement featuring 23 jewels. This movement includes the "SS" or Second Setting feature, which allows the seconds hand to halt when the crown is pulled, enabling precise time synchronization. The movement appears clean and free of corrosion. Timegrapher testing indicates a rate of -50 to -55 seconds per day which indicates a healthy movement. Strap The watch is fitted with its original stainless steel link bracelet featuring a signed Seiko 5 Actus folding clasp. The bracelet matches the case finish perfectly and is sized to fit a wrist of approximately 18 cm. The links show normal stretch and surface wear commensurate with the age of the timepiece. Condition This timepiece is in Good vintage condition. While the case and bracelet show honest wear with surface scratches and handling marks, the watch retains its structural integrity and aesthetic appeal. The dial is remarkably well preserved, and the faceted crystal remains the visual highlight despite minor wear. Dimensions The case measures 37 mm in diameter excluding the crown, offering a classic vintage presence that is both comfortable and visually impactful on the wrist. Remarks The Seiko 5 Actus SS with a faceted crystal is becoming increasingly sought after by enthusiasts who appreciate the bold experimentation of 1970s design. The combination of the brown vignette dial and the "cut glass" crystal gives this watch a unique character that changes depending on the lighting conditions. It is a fantastic representation of the JDM (Japanese Domestic Market) style from a golden era of horology. History Introduced in the late 1960s, the Seiko 5 Actus series was a step up from the standard Seiko 5, offering higher jewel counts and hacking capabilities in the "SS" models. These watches were designed to be durable yet fashionable, incorporating exotic dial colors and case shapes that defined the disco era. Produced in January 1974, this specific watch houses the 6106 movement, a legendary caliber known for its durability and for serving as the base architecture for some of Seiko's most famous diver and chronograph movements. / Second Vintage SKU: SEINIBJGN0000
