Brand: Seiko Model: 5 Actus Reference Number: 7019-7210 Serial Number: 371292 Movement: Automatic Caliber 7019A Dial: Emerald green sunburst with faceted crystal Case Size: 37 mm Case Material: Stainless Steel Production Year: 1973 Condition: Excellent vintage condition with a pristine dial and well-preserved case, showing healthy movement performance. Dial and Hands The dial is the centerpiece of this timepiece, presenting a deep emerald green tone with a rich sunburst finish that shifts shades depending on the lighting. It features polished applied baton hour markers that add depth and contrast against the green surface. The hands are polished silver-tone batons with luminous inlays that match the markers. A framed day and date window is positioned at the three o'clock position. The entire face is viewed through the original faceted mineral crystal, which features horizontal and vertical cuts that refract light dramatically, a signature design element of the premium Actus models from this era. Case and Crystal The stainless steel case features a classic 1970s cushion shape with brushed upper surfaces and polished sides, retaining its original sharp lines and geometry. The crown is recessed at the four o'clock position, a practical design choice often seen in Seiko's automatic range to ensure comfort during daily wear. The faceted crystal is in remarkable condition for its age, preserving the sharp edges of the glass cuts which are essential to the watch's character. The screw-down caseback is clearly engraved with the reference and serial numbers, along with the Suwa Seikosha factory logo. Movement Powering the watch is the reliable Seiko Caliber 7019A automatic movement, a 21-jewel mechanism renowned for its durability and efficiency. This movement features a quickset function for the date. The movement is clean and presents well, offering reliable vintage performance. Timegrapher testing indicates the watch is running at approximately 6 seconds per day, which indicates a very healthy movement operating well within, and indeed surpassing, typical vintage tolerances. Strap The watch is fitted with its original stainless steel link bracelet, which is a significant collector's detail. The bracelet features a folding clasp signed with the "Seiko 5 Actus" logo. It is currently sized to fit a wrist circumference of approximately 17.5 cm and complements the case design perfectly. Condition This timepiece is in excellent vintage condition. The dial is flawless with no visible staining or degradation. The case shows honest signs of light wear consistent with careful usage over five decades but retains its architectural integrity without signs of over-polishing. The faceted crystal is clear and sharp. The movement is running strong and accurate. Dimensions The case measures 37 mm in diameter, excluding the crown, making it a versatile size that sits comfortably on a variety of wrist sizes. The lug-to-lug distance ensures a balanced profile, while the thickness usually associated with automatic movements gives it a substantial yet wearable presence. Remarks The combination of the vibrant green dial and the cut glass crystal makes this specific reference one of the more desirable variations of the Actus line. It is a watch that embodies the funk and flair of the 1970s while maintaining the restrained quality Seiko is known for. Finding an example with the crystal and dial in such well-preserved condition is becoming increasingly difficult for collectors. History The Seiko Actus line was introduced in the late 1960s and ran through the 1970s, positioned as a stylish, slightly upmarket alternative to the standard Seiko 5, specifically targeting young professionals in Japan. Produced by the Suwa Seikosha factory, these watches were built to be both robust daily wearers and fashionable accessories. This specific example, produced in July 1973, captures the peak of this design philosophy, offering a glimpse into a golden era of Japanese horology where experimentation with color and case geometry was celebrated. / Second Vintage SKU: SEI-SAJ-0008
