The dauphine-style hands are sharp and polished, complementing the minimalist aesthetic. A subtle yet elegant detail is the fine fluted ring surrounding the dial, adding depth and texture to the visual presentation. The text "Seikomatic-R" and "Diashock 30 Jewels" is crisp and legible. Case and Crystal The stainless steel case measures a substantial 38mm, offering a significant wrist presence for a watch from this era. The case design features a recessed, hidden crown at the 4 o'clock position, a signature trait of the Seikomatic line intended to emphasize the automatic winding capability, rendering manual winding unnecessary. The case is in honest vintage condition, showing visible scratches and surface marks on the lugs, bezel, and sides, expected from a watch of this age. The caseback features the iconic Seiko "Dolphin" emblem and clearly visible reference engravings, though some tool marks are present. The acrylic crystal is clear with no distracting flaws. Movement Powering this timepiece is the robust Seiko Caliber 8305B automatic movement. This high-grade mechanism features 30 jewels, significantly more than the standard 17 or 21 jewels common in the era, ensuring reduced friction and longevity. The movement is clean and visually appealing. Timegrapher results show the watch is running between -20 and -29 seconds per day, which indicates healthy movement function. Strap The watch is fitted with a new black leather strap featuring an alligator grain pattern and a silver-tone steel buckle. The strap is in unworn condition and provides a classic, dressy contrast to the stainless steel case, making it ready for immediate wear. Condition This timepiece is rated in Good vintage condition.

The movement is operational and offering reliable vintage performance. Dimensions With a diameter of 38mm excluding the hidden crown, the watch wears larger than many of its 34-36mm contemporaries. The lug-to-lug length ensures a comfortable fit on a variety of wrist sizes, balancing vintage elegance with modern wearability. Remarks The Seikomatic-R 8305-9010 is a testament to Seiko's golden era of mechanical watchmaking. The combination of the hidden crown, the coin-edge bezel detail, and the high-jewel movement makes this a technically and aesthetically interesting piece for collectors. The distinct Dolphin caseback confirms its heritage as a water-protected model designed for durability. History Introduced in the mid-1960s, the Seikomatic range was Seiko's primary automatic line, showcasing their mastery of self-winding technology. The "R" designation in Seikomatic-R typically indicated a refined or robust version, often utilizing the 83xx series movements which were thinner and more efficient than earlier calibers. Produced in May of 1965, this specific watch predates the widespread quartz revolution, representing the peak of accessible mechanical luxury from the Suwa Seikosha factory. / Second Vintage SKU: SEI-SMD-0006
