Dial and Hands
The dial of this Seikomatic is a radiant silver with a fine sunburst finish that catches the light beautifully. It features applied, faceted gold-tone baton indices that provide excellent contrast and legibility. The typography is crisp, with the "Seikomatic Self Dater" script elegantly placed below the Seiko gyro logo at twelve o'clock, and "Diashock 24 Jewels" printed above six o'clock alongside the Suwa Seikosha symbol. The framed date window at three o'clock adds practical functionality. The gold-tone dauphine hands are sharp and well-preserved, complementing the indices perfectly. Upon close inspection, the dial remains exceptionally clean, showing only the faintest, most microscopic signs of age, presenting a truly stunning vintage face.
Case and Crystal
The 36mm case is constructed of gold-filled material, offering a warm, classic appearance. The lug profile retains its definition, though honest signs of wear, such as light surface scratches and minor softening of the edges, are visible, consistent with its vintage nature. The transition between the case flanks and the lugs shows the natural patina of a watch that has been worn and enjoyed. The crystal is domed and clear, providing an unobstructed view of the dial beneath, with no major scratches or scuffs to detract from the overall aesthetic. The snap-on caseback is marked "EGP BACK GOLD FILLED" and features the Seikomatic dolphin motif, along with the serial number 15022 and reference 3704863.
Movement
Powering this timepiece is a Seikosha 24-jewel automatic movement, proudly displayed in the provided images. The rotor is clearly engraved with "SEIKOMATIC 24 JEWELS" and "SEIKOSHA" in gold lettering, contrasting beautifully against the brushed steel of the movement plates. The movement appears clean and well-maintained. Running in vintage operational condition. Maintains the authentic mechanical character of the era. The timegrapher result is -40 to -49 s/d.
Strap
The watch is fitted with a handsome black textured leather strap featuring contrasting tan stitching. This strap complements the vintage character of the gold-filled case and provides a comfortable and stylish wearing experience. The gold-tone buckle matches the case material nicely.
Condition
This Seikomatic is in good vintage condition. The dial is exceptionally well-preserved, standing out as a highlight of the piece. The gold-filled case shows normal, honest wear expected from a watch of its age, including minor surface marks and light patina, but no severe damage or deep gouges. The movement is clean and fully operational. Overall, it is a highly attractive and wearable vintage Seiko.
