Dial and Hands The silver sunburst dial is the highlight of this timepiece, preserved in very attractive condition with a light, even warmth. It features substantial applied block indices that catch the light beautifully, complemented by polished sword-style hands. A framed day-date window is positioned at 3 o'clock, notably displaying the day in Kanji characters, a feature highly prized by collectors. The distinct "DX" and "25 Jewels" badging above 6 o'clock confirms its deluxe specification. Case and Crystal The stainless steel case features the classic "C-shape" or cushion profile that defines late 60s Seiko design. The case sits comfortably on the wrist at 38mm, offering a substantial vintage presence. The crown is recessed at the 4 o'clock position, a signature design element intended to streamline the case silhouette. The surface shows visible scratches and marks consistent with a watch that has been enjoyed over the decades, retaining its original geometry. The caseback proudly displays the "Waterproof" engraving, a detail specific to pre-1970 production models. Movement Powering the watch is the robust Seiko Caliber 6106 automatic movement, featuring 25 jewels. This movement series was a technological step up for Seiko, introducing hacking capabilities in many iterations to allow for precise time setting. Timegrapher testing indicates a rate of approximately +49 to +52 seconds per day, which indicates an active movement that is running and operational. Strap The watch is fitted with a black leather strap featuring contrasting white stitching. The strap is in good condition and complements the monochrome aesthetic of the silver dial and steel case, making it ready for immediate wear. Condition This timepiece is in Good vintage condition. The case shows normal vintage wear with scratches and small nicks visible throughout, characteristic of an honest 1960s tool watch. The dial is well-preserved, showing only minimal signs of aging. The movement is functioning, offering reliable vintage performance as indicated by the timegrapher results. Dimensions With a case diameter of 38mm, this Seiko 5 DX wears slightly larger than many dress watches of its era due to the cushion case shape. It offers a modern presence on the wrist while maintaining classic vintage proportions. Remarks The Seiko 5 DX (Deluxe) 6106-8131 is a standout reference for enthusiasts of JDM (Japanese Domestic Market) styling, particularly due to the Kanji day wheel. The combination of the recessed crown, the "Waterproof" proofed caseback, and the specific production date of November 1968 makes this a historically specific and collectible example. History Introduced in 1963, the Seiko 5 set the standard for affordable, robust automatic watches. The "DX" or Deluxe line was introduced subsequently to offer a higher tier of finish and specification, often including higher jewel counts and improved movements like the 6106. These watches were designed for the active professional of the 1960s and played a crucial role in establishing Seiko's global reputation for mechanical reliability. / Second Vintage SKU: SEIXH7KOE0000
