The watch shows honest signs of age, particularly to the case plating, while the dial remains in spectacular condition. Timegrapher results show -10s/day which indicates healthy movement. Dial and Hands The silver sunburst dial is the highlight of this timepiece, presented in remarkable condition with a crisp, radiating finish. It features the signature "Seikomatic" script and "Diashock 26 Jewels" text, which remain sharp and legible. The layout is characterized by the framed day window positioned at 6 o'clock, displaying Kanji characters, and a separate date window at 3 o'clock. The applied gold-tone baton indices are multi-faceted to catch the light, complemented by sharp gold-tone dauphine hands that add to the dressy aesthetic. Case and Crystal The 36mm case is finished in gold plating, featuring the distinctively recessed crown at the 4 o'clock position, a design choice intended to streamline the silhouette and emphasize the automatic nature of the movement. The case shows visible vintage wear, with plating loss evident on the high edges of the lugs and bezel, revealing the base metal underneath, consistent with a watch that has been enjoyed over the decades. The screw-down stainless steel caseback prominently features the embossed Seiko Dolphin logo, a symbol of water resistance standards of the era, along with the reference and serial numbers. The crystal is clear and presents well. Movement Powering the watch is the robust Seiko Caliber 6206B, a 26-jewel automatic movement known for its reliability and efficiency. This mechanism features Seiko's proprietary Diashock anti-shock system. The movement is running within vintage tolerances, with a timegrapher reading of -10 seconds per day, offering reliable vintage performance. Strap The watch is fitted with a new black leather strap featuring contrasting stitching, which complements the black details of the indices and adds a casual elegance to the gold-tone case. Condition This timepiece is rated in Good vintage condition. While the case demonstrates evident wear and patina, specifically the softening of the gold plating on the lug edges and general surface marks, the dial has been preserved to a standard that borders on stunning. The overall appearance is honest, balanced, and retains the strong character of a genuine vintage piece from 1965. Dimensions With a diameter of 36mm excluding the crown, the watch sits comfortably on the wrist, embodying the classic mid-century dress watch proportions that work perfectly in modern contexts. Remarks The Seikomatic line was a premium offering in the 1960s, often serving as a testing ground for technologies that would eventually find their way into the Grand Seiko line. This specific "Weekdater" configuration, with its Kanji day wheel and 6206 movement, represents a specific moment in Seiko's history where functional durability met high-end design. History Introduced in the early 1960s, the Seikomatic series was pivotal in establishing Seiko's reputation for automatic watches. The "Weekdater" models were designed for the busy salaryman, providing essential calendar information at a glance. The use of the Dolphin logo on the caseback signifies the "Water Proof" specification of the time, marking these watches as practical daily wearers that helped Seiko dominate the Asian market before expanding globally. / Second Vintage SKU: SEI-SNX-0001
