Presented for auction by Second Vintage This distinguished Seiko timepiece exemplifies the golden era of mid-century Japanese watchmaking, capturing the elegant aesthetic and mechanical ambition of the 1960s. The Seikomatic Weekdater stands as a historically significant model for the brand, celebrated by collectors for its perfectly balanced dial architecture, most notably the distinctive placement of the day display at the six o'clock position. This layout not only provided practical daily functionality but also maintained a refined, symmetrical dress watch appearance that remains highly sought after today. Brand: Seiko Model: Seikomatic Weekdater Reference Number: 6206-8990 Serial Number: 4305437 Movement: Automatic, Caliber 6206A, 26 Jewels Dial: Silver sunburst dial with applied faceted indices, showing light age-consistent spotting and crisp typography Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1964 Condition: Good vintage condition with honest signs of wear and a beautifully preserved sunburst dial Dial and Hands The watch features a striking silver sunburst dial that catches the light beautifully, providing a dynamic backdrop to the elegant layout. The typography is exceptionally crisp, featuring the elegant "Seikomatic Weekdater" script below twelve o'clock and the "WATER 30 PROOF / DIASHOCK 26 JEWELS" designation cleanly printed above the six o'clock day window. The dial furniture consists of prominent applied faceted rectangular indices, each detailed with a central black stripe for enhanced legibility. The day of the week is displayed in a charming blue font within a recessed window at six o'clock, complementing the framed date window at three o'clock. The classic Dauphine hands retain their original luminous material, which has gracefully aged to a creamy, slightly greenish hue. Upon close inspection, the dial exhibits light, age-consistent spotting near the outer edges, and the metal surfaces of the hands and indices show minor oxidation and micro-scratches indicative of an honest vintage life, presenting a highly attractive and authentic overall appearance. Case and Crystal The 37 mm stainless steel case offers a substantial and modern presence on the wrist, characterized by a smooth, polished bezel and sweeping lugs. The case lines remain well-defined, with the transition between the polished surfaces and the lug profiles retaining good structural integrity. As expected for a timepiece of this vintage, the case and bezel display honest signs of wear, including scattered surface scratches, handling marks, and minor softening along the outer edges. The domed acrylic crystal protects the dial effectively, showing only light superficial wear that does not detract from the clear visibility of the dial beneath. The smooth caseback is clearly engraved with the serial number 4305437, remaining fully legible despite standard wear marks from previous use. Movement Powering this timepiece is the Seiko Caliber 6206A automatic movement, a robust 26-jewel mechanism renowned for its reliability. The movement features a distinctive gold-tone finish across the rotor and main plates, clearly stamped with the Seiko branding, jewel count, and caliber designation. Visually, the movement displays noticeable age-related patina, including spotting and oxidation on the rotor and bridges, which is consistent with the watch's mid-century origins. Performing well within expected vintage tolerances; running strong and steady. [-21s to -25s/day]. Strap The watch is fitted with a period-correct black textured strap featuring a distinct crosshatch pattern and contrasting white perimeter stitching. The strap is secured with a classic stainless steel pin buckle, offering a comfortable and stylish complement to the silver-toned dial and case. Condition This timepiece is presented in good vintage condition. The case exhibits normal vintage wear with moderate handling marks while retaining its fundamental shape. The dial is a standout feature, boasting a vibrant sunburst finish with only minor, acceptable spotting and light oxidation on the handset. The movement shows visible cosmetic patina but operates steadily within stated parameters. Dimensions The stainless steel case measures 37 mm in diameter, excluding the crown, providing a highly versatile and wearable profile that bridges the gap between classic vintage sizing and modern preferences. Remarks The Seikomatic Weekdater remains a quintessential example of vintage Seiko design language. Its combination of the Caliber 6206 automatic movement and the iconic six o'clock day window makes it a compelling acquisition for both seasoned Seiko enthusiasts and those looking to add a character-rich vintage dress watch to their collection. History Introduced in the early 1960s, the Seikomatic line represented Seiko's dedication to producing high-quality, self-winding timepieces for the discerning professional. The Weekdater variant, with its expanded calendar complication, was marketed as the ultimate daily companion for the modern businessman. By positioning the day of the week at six o'clock, Seiko achieved a harmonious dial balance that distinguished the Weekdater from its Swiss contemporaries, cementing its legacy as a masterpiece of functional mid-century Japanese design. / Second Vintage SKU: SEI-MWJ-0001
