The gold-tone dauphine hands are crisp and legible, complementing the applied Seiko logo and the framed date window at the three o'clock position. The text, including the "Diashock 30 Jewels" designation, remains distinct and perfectly preserved. Case and Crystal The watch is housed in a gold-plated case measuring a substantial 37mm, which offers a modern presence for a vintage dress watch. The case exhibits honest signs of age and wear, with visible plating loss on the high edges of the lugs and bezel, revealing the base metal underneath in a manner typical for gold-plated watches from this period. The caseback features the iconic Seiko Dolphin emblem, a symbol of the Seikomatic line, along with clearly legible reference and serial engravings. The crystal is clear and presents well. Movement Powering the watch is the Seiko Caliber 8305B, a robust automatic movement featuring an impressive 30 jewels, which was a high specification for the era. The movement appears visually clean and well-maintained. Timegrapher testing displays a rate of approximately -56 to -60 seconds per day, which indicates the movement is operational and running. Strap The watch has been fitted with a black leather strap featuring contrasting gold-tone stitching. This strap choice perfectly accents the gold-plated case and dial indices, enhancing the overall vintage dress appeal of the timepiece. Condition This timepiece is in good vintage condition. While the case shows expected wear and patina to the gold plating consistent with a watch from the mid-1960s, the dial remains in stunning condition. The movement is functioning, and the overall structural integrity of the watch is sound. Dimensions The case measures 37mm in diameter excluding the crown, making it a very wearable size for contemporary tastes while retaining its vintage proportions. Remarks The Seikomatic-R series is often celebrated by enthusiasts for bridging the gap between Seiko's mid-range offerings and their high-end Grand Seiko lines of the time. The inclusion of a 30-jewel movement in this reference 8305-0020 demonstrates Seiko's commitment to quality and longevity. This specific example, with its beautiful dial and honest case character, is a charming representative of 1965 production.
