The dial furniture is meticulously executed, featuring applied gold-tone faceted baton indices with distinct black center stripes that enhance legibility. At twelve o'clock, the applied Seiko Sportsmatic 5 shield sits proudly above crisp, black serif and sans-serif typography denoting the "Deluxe," "WATER 30 PROOF," and "DIASHOCK 23 JEWELS" specifications. A framed day-date aperture is positioned at three o'clock. The time is indicated by sharp, gold-tone dauphine hands and a slender sweeping center seconds hand. Upon close inspection, the dial remains in stunning condition, appearing remarkably clean and free of moisture marks, spotting, or discoloration, showcasing an exemplary level of preservation for its age. Case and Crystal The 37mm case features a classic mid-century profile, executed in heavy gold plating (EGP) over a base metal, capped with a stainless steel snap-on caseback. The design incorporates a recessed crown at the four o'clock position, emphasizing the automatic nature of the movement, alongside a dedicated pusher at three o'clock for the date quickset function. The case exhibits clear, honest signs of vintage wear. There is noticeable brassing and plating loss along the outer edges of the bezel and the tips of the lugs, revealing the base metal beneath and telling the story of decades of faithful wear. The lugs maintain their fundamental shape without heavy over-polishing. The stainless steel caseback displays the faint, classic Seiko dolphin motif, alongside clearly stamped reference and serial numbers. A domed acrylic crystal protects the dial, remaining clear and offering an undistorted view of the pristine display beneath. Movement Powering this timepiece is the Seiko Caliber 7606A, a 23-jewel automatic movement renowned for its reliability and efficient winding. Visual inspection of the movement reveals clean plates and a rotor distinctively stamped with red "SEIKO SPORTSMATIC 23 JEWELS" typography, alongside the clearly engraved caliber designation. Performing well within expected vintage tolerances; running strong and steady. Timegrapher results indicate an output of +20 to +24 seconds per day.

The dial and hands are in exceptional, near-mint condition, having been perfectly protected over the decades. The exterior case shows fair to good vintage condition, with clear signs of daily use, specifically the aforementioned plating wear and brassing around the bezel lip and lug edges. This honest wear provides a charming, authentic patina that vintage enthusiasts often appreciate, while the pristine dial ensures the watch remains incredibly attractive on the wrist. Dimensions The watch measures a versatile 37 mm in diameter, excluding the recessed crown. This dimension provides a substantial yet elegant presence on the wrist, wearing true to the classic proportions of 1960s dress watches. Remarks This Seiko Sportsmatic 5 Deluxe is a highly wearable piece of horological history. It offers the collector a chance to own a watch with a dial that looks nearly as fresh as it did in the 1960s, paired with a case that carries the authentic, unpolished marks of a life well-lived. The reliable 7606A caliber and the striking contrast of the yellow-stitched leather strap make this a versatile and charismatic addition to any vintage collection. History Introduced in the early 1960s, the Sportsmatic line was instrumental in defining the core tenets of the now-iconic Seiko 5 collection: an automatic movement, a day-date display, water resistance, a recessed crown, and a durable case. The "Deluxe" variant was introduced as a premium offering within this family, featuring higher jewel counts, elevated dial finishing, and sophisticated case designs. These watches were aimed at the upwardly mobile professional, offering Swiss-rivaling technology, such as the Diashock anti-shock system and the Magic Lever winding mechanism, at an accessible price point. Today, they are celebrated by collectors as prime examples of Seiko's golden age of mechanical watchmaking. / Second Vintage SKU: SEI-SSD-0052
