Timegrapher: +28s+30s/day, running strong and steady. Dial and Hands The watch features a well-preserved and attractive silver dial with a clean sunburst finish. The applied gold-tone indices remain in excellent shape, providing a sharp contrast against the silver background. Crisp printing is maintained throughout the dial, prominently displaying "DIASHOCK 17 JEWELS" with no significant loss or staining. The gold-tone dauphine hands exhibit honest aging consistent with the watch's era, showing light oxidation and minor spotting visible under magnification. Case and Crystal The gold-plated case is heavily worn, showing significant plating degradation. There is noticeable plating loss on the lugs and case edges, alongside moderate scratches throughout the case flanks. Corrosion and pitting are visible on the rear edges of the case. The integrated smooth bezel shows scratches and noticeable plating wear along its periphery. A recessed crown is positioned at 4 o'clock, which also shows some plating wear, keeping the case profile sleek. The domed acrylic crystal remains clear with no major cracks or chips, though some light surface scratches are visible at certain angles. Movement Powering the watch is the automatic Seikosha caliber 603. The movement appears relatively clean, featuring engravings that read "SEIKOMATIC 20 JEWELS", "SEIKOSHA", and "603". There are some light scratches present on the rotor. The rotor is stamped 20 jewels, which conflicts with the 17 jewels printed on the dial, indicating a parts mismatch. Measuring +28s+30s/day on the timegrapher. Performing well within expected vintage tolerances; running strong and steady. Strap The watch is paired with a complementary black leather strap featuring contrast stitching. The strap shows light wear and creasing, providing a comfortable and traditional aesthetic. Condition Good vintage condition. The dial is the clear highlight, remaining exceptionally clean with well-preserved indices and crisp printing. The case exhibits heavy wear, with significant plating loss on the lugs and edges, moderate scratches on the flanks, and pitting on the rear edges. The hands show light, honest oxidation. The acrylic crystal has mild surface scratches, and the smooth bezel displays noticeable plating wear.

Dimensions The case measures 35 mm (excluding the crown). Remarks This Seikomatic offers an extremely clean and attractive sunburst dial paired with the classic, streamlined 4 o'clock crown case design. While the case shows heavy wear and the movement features a parts mismatch, the strong dial presentation and steady mechanical performance make it a charming vintage wearer. History The Seikomatic line was introduced in the early 1960s as a premium automatic offering from Seiko, showcasing the brand's advancements in self-winding technology. The recessed crown at 4 o'clock became a signature design element for these models, emphasizing that the watch did not require daily manual winding. The Seikosha caliber 603 is a reliable automatic movement characteristic of Seiko's robust engineering during this period, built to provide dependable daily performance.
