This piece represents a golden era of Seiko manufacturing where durability met sophisticated design, making it a highly collectible piece for enthusiasts of vintage Japanese horology. Brand: Seiko Model: 5 Actus SS Reference Number: 6106-8680 Serial Number: 5N5077 Movement: Automatic Caliber 6106C Dial: Deep blue sunburst with applied indices Case Size: 38 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1975 Condition: Near-mint vintage condition. The watch presents exceptionally well with sharp case lines and a vibrant dial. Measurements on the timegrapher indicate a rate of +19 to +25 seconds per day. Dial and Hands The dial is finished in a striking deep blue sunburst texture that radiates from the center and changes tone depending on the viewing angle. It is adorned with blocky, faceted applied silver hour markers that catch the light efficiently. The baton-style hands are polished silver with central luminous inserts providing excellent contrast against the dark background. A framed day-date window sits at the three o'clock position, featuring the desirable Kanji and English day wheel characteristic of JDM models. The dial is marked with the applied Seiko 5 Actus logo and the printed SS 23 Jewels designation. Case and Crystal The stainless steel case features the classic 1970s cushion geometry with a recessed crown tucked neatly at the four o'clock position. The case finishing is excellent, displaying strong brushing on the upper surfaces and polished flanks that remain sharp and well-defined. The watch is fitted with a flat mineral glass crystal rather than the faceted variety often found on Actus models, providing a cleaner look and superior legibility. Both the case and crystal show minimal signs of handling and preserve the original architecture of the watch. Movement Powering this timepiece is the robust Seiko Caliber 6106C automatic movement. This 23-jewel mechanism is renowned for its durability and features the "Second Setting" hacking function, which stops the seconds hand when the crown is pulled out for precise time setting. The movement also offers a quickset feature for the day and date which is activated by pushing the crown in. Timegrapher results show an accuracy of +19 to +25 seconds per day. Which indicates healthy movement offering reliable vintage performance. Strap The watch is paired with a high-quality brown leather strap with an alligator grain pattern. The rich brown tone of the leather provides a sophisticated contrast to the cool tones of the blue dial and steel case. It is finished with a polished stainless steel buckle that complements the case design. Condition This timepiece is in near-mint condition. The dial is exceptionally clean with vibrant color and no visible spotting or damage. The stainless steel case retains its original factory lines with distinct brushing on the top surfaces and mirror-polished sides showing almost no wear. The movement is clean and functions correctly. Dimensions With a case diameter of 38 mm, the watch sits prominently on the wrist while maintaining a comfortable profile typical of vintage Seiko dress watches. The lug design integrates smoothly into the case shape, ensuring a balanced fit on a variety of wrist sizes. Remarks The Seiko 5 Actus SS occupies a sweet spot in vintage collecting, offering higher specifications than the standard Seiko 5 of the era thanks to the hacking 6106 movement. This specific example, with its flawless blue dial and sharp case preservation, is a collector-grade specimen that captures the essence of 1970s JDM style. History Introduced in the late 1960s and produced through the 1970s, the Seiko 5 Actus line was marketed as a stylish and durable watch for the young, active professional. It bridged the gap between the entry-level Seiko 5 and the higher-end Lord Matic series. The "SS" designation highlighted the technological advancement of the hacking second hand, a feature that was becoming standard in higher-grade watches of the time. These pieces were primarily sold in Japan, making well-preserved examples with Kanji date wheels highly sought after by international collectors today.
