Case and Crystal The stainless steel case features the classic "Grammar of Design" influence with sharp lines and separate polished and brushed surfaces.

The caseback is a screw-down type in stainless steel, clearly displaying the reference and serial details. The crystal is clear and provides excellent visibility of the dial.

The movement appears clean and well-maintained, offering reliable vintage performance. Strap The watch is fitted with a new black leather strap featuring contrasting white stitching. The matte finish of the leather complements the high-polish elements of the case and the silver tones of the dial, giving the watch a versatile and sporty appearance suitable for daily wear. Condition This timepiece is in excellent vintage condition. The case retains sharp edges with only minor surface handling marks consistent with its age. The dial is exceptionally well-preserved, showing no visible signs of patina or degradation. The hands and indices are bright and clean. Timegrapher readings indicate an accuracy of +1 to +4 seconds per day with strong amplitude, which indicates a healthy movement and exceptional performance for a watch of this vintage, typical of a recently serviced mechanism. Dimensions The case measures approximately 37 mm in diameter, providing a classic vintage sizing that sits comfortably on a variety of wrist sizes. The lug-to-lug length ensures a balanced profile, while the thickness is moderate, allowing it to slide easily under a shirt cuff. Remarks This 5 Actus represents the golden era of Seiko mass-luxury production. The combination of the Kanji day wheel, the specific 7019-7060 case geometry, and the flawless silver dial makes this a standout piece. It is rare to find everyday pieces from 1971 preserved with such dial clarity and mechanical precision. History Introduced in the late 1960s, the Seiko 5 Actus series was marketed as a step up from the standard Seiko 5, offering higher manufacturing quality and more adventurous designs. The "Actus" name (Latin for "action" or "impulse") reflected Japan's rapid economic growth and the energetic lifestyle of the younger generation. Produced at the Suwa Seikosha factory, these watches have since gained a cult following for their robust build quality and distinct mid-century modern styling. /Second Vintage SKU: SEI-SAN-0001
