Dial and Hands The dial is a stunning example of 1970s design, featuring a gradient finish that transitions from a bright gold-bronze in the center to a deep chocolate brown at the periphery. It is adorned with applied silver baton hour markers that remain crisp and reflective. The baton-style hands are well-preserved, complementing the indices perfectly. A framed day and date window is positioned at 3 o'clock, displaying the day in Kanji, which confirms the Japanese Domestic Market heritage of this piece. The applied "Seiko" and "5 Actus" logos are intact and sharp, floating above the "SS" and "23 Jewels" text. Case and Crystal The stainless steel case features a distinct geometric shape typical of the period, often referred to as a helmet or C-shape profile. The case lines remain sharp and defined, showcasing the original brushed finish on the top surfaces and polished sides. There are nominal signs of vintage wear consistent with careful usage. The defining feature of this watch is the original faceted Hardlex crystal, which features horizontal and vertical cuts that play with the light and distort the dial markers in a charming, kaleidoscopic manner. Movement Powering the watch is the reliable Seiko Caliber 6106C automatic movement, a 23-jewel workhorse known for its durability. This "SS" variant includes the hacking feature, allowing the seconds hand to stop for precise time setting. Timegrapher testing indicates a rate of +36 to +46 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a matching dark brown leather strap that complements the warm tones of the gradient dial. The strap is in excellent, clean condition and secures with a stainless steel buckle, offering a comfortable fit ready for immediate wear. Condition This timepiece presents in excellent vintage condition. The dial is exceptionally clean, free from blemishes or spotting. The case retains its factory geometry with very respectable preservation, showing only minor handling marks. The movement is clean and correct, and the overall presentation is that of a well-cared-for collector's piece. Dimensions The case measures 38 mm in diameter excluding the crown, offering a substantial yet wearable presence on the wrist typical of 1970s sizing. The lug width accommodates standard straps, making it versatile for future styling changes. Remarks The Seiko 5 Actus line was originally marketed towards the young, upwardly mobile Japanese generation of the 1970s, blending style with technology. This specific reference, with its "SS" designation and faceted crystal, is among the more desirable configurations. It perfectly captures the transition era of Seiko design where experimentation with texture and light was at its peak. History Produced in November 1975 based on the serial number, this watch hails from the Suwa Seikosha factory. The 6106 movement largely paved the way for the legendary 6139 chronograph movements and is revered for introducing the "magic lever" winding system's efficiency. The Actus series remains a cult favorite today for offering some of the most adventurous dial and crystal combinations in Seiko's vast archive. /Second Vintage SKU: SEISAVPNC0000
