Available now on auction by Second Vintage This is a remarkable example of Seiko's domestic Japanese design philosophy from the 1970s, featuring one of the most striking dials produced for the Actus line. The Seiko Actus SS is highly collectible today for its robust build quality and adventurous dial variants, and this specific piece boasts a mesmerizing teal blue dial with a vertical brushed texture that catches the light beautifully. Paired with its original signed bracelet and powered by the higher-specification 6306 hacking movement, this is a vintage piece that combines distinct 1970s aesthetics with practical daily wearability. Brand: Seiko Model: Actus SS Reference Number: 6306-7010 Serial Number: 6N3289 Movement: Automatic Caliber 6306A Dial: Teal blue with vertical brushed texture Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1976 Condition: Excellent vintage condition with a pristine dial and honest wear to the case. Timegrapher readings indicate active movement health. Dial and Hands The dial is the absolute highlight of this timepiece, presenting a vibrant teal blue hue with a deep vertical brushed finish that resembles a fine woodgrain or denim texture. It features rare applied Arabic numeral hour markers in a crisp white finish, giving the watch a legible and slightly field-watch aesthetic unique to this reference. The baton-style hands are polished and retain their original luminous inserts, matching the small lume plots at the outer track. The day and date window is framed in steel at the 3 o'clock position, with the "SS" (Stop Second) logo prominently displayed above the 6 o'clock mark. Case and Crystal The stainless steel case features the classic Seiko geometry of the mid-1970s, with a blend of polished surfaces and sharp lines. The case remains in very good condition with defined edges, showing only minor surface scratches consistent with careful vintage usage. The crown is recessed at the 4 o'clock position, a signature design choice for the Actus line to ensure comfort on the wrist. The crystal is clear and allows the textured details of the dial to stand out without distraction. Movement Powering the watch is the desirable Seiko Caliber 6306A, a 21-jewel automatic movement known for its robustness and the inclusion of a hacking feature (seconds hand halts when setting time), which was an upgrade over the standard Actus 7019 movements. The movement is clean and currently running between +25 and +30 seconds per day based on timegrapher results, which indicates healthy movement providing reliable vintage performance. Strap The watch comes fitted on its original stainless steel bracelet, complete with the correct "Seiko Actus" signed folding clasp. The bracelet design complements the case perfectly and accommodates a wrist size of approximately 19cm. It remains tight and comfortable, preserving the original look and feel of the watch as it was sold in 1976. Condition This timepiece is in excellent vintage condition. The dial is exceptionally well-preserved with no visible staining, oxidation, or damage to the texture. The case shows honest signs of age in the form of light hairline scratches but lacks any significant dings or deep impact marks. The movement is functioning correctly with the day and date quickset working as intended. Dimensions The case measures 35 mm in diameter excluding the crown, offering a classic vintage fit that slides easily under a cuff. The lug-to-lug distance ensures a balanced presence on a variety of wrist sizes. Remarks Finding a Seiko Actus with this specific teal texture dial and Arabic numeral configuration is becoming increasingly difficult. The combination of the vibrant color, the rare "SS" specification 6306 movement, and the original bracelet makes this a comprehensive collector's package. It is a stunning representation of why vintage Seikos are so revered, offering incredible dial complexity and mechanical reliability. History The Seiko Actus line was introduced in the late 1960s and ran through the 1970s as a dedicated series for the younger Japanese domestic market. It was positioned as a stylish yet durable watch for the emerging white-collar professional. The "SS" designation on this model refers to "Second Setting," highlighting the hacking capability of the 6306 movement, a feature that was considered a premium technical specification at the time. This specific example, produced in November 1976, captures the peak of Seiko's creative dial manufacturing during the golden era of mechanical watchmaking.
