Seiko Seikomatic 夢則 (Yumusoku) 6206-8040 (1965)

Offered in this auction by Second Vintage This Seiko Seikomatic reference 6206-8040 is a quintessential example of mid-1960s Japanese design, representing the golden era of Seiko's automatic dress watches. Often referred to as the "Weekdater" due to its distinctive layout, this timepiece combines practical utility with timeless elegance, featuring a high-grade movement and a sophisticated aesthetic that rivals Swiss contemporaries of the period. Brand: Seiko Model: Seikomatic Reference Number: 6206-8040 Serial Number: 5000896 Movement: Automatic Caliber 6206B Dial: Silver Sunburst Case Size: 36 mm (excluding the crown) Case Material: Gold Plated and Stainless Steel Production Year: 1965 Condition: Good vintage condition. Timegrapher results included. Dial and Hands The silver sunburst dial is the highlight of this timepiece, preserved in beautiful condition with a radiant finish. It features multi-faceted applied gold baton hour markers and sharp gold dauphine hands that catch the light elegantly. The layout is defined by the framed date window at three o'clock and the full day aperture located at the six o'clock position, a signature of the Weekdater line. The applied "Seiko" logo and printed "Seikomatic Diashock 26 Jewels" text are crisp and intact. Case and Crystal The case is finished in gold plating with a stainless steel caseback. It retains its classic form, showing honest signs of wear and age throughout. There is a visible mark on the bezel distinct near the 12 o'clock position, along with general wear to the plating consistent with a watch from 1965. The screw-down caseback features the iconic and desirable dolphin emblem, which remains clearly legible. The crystal is clear and presents well. Movement Inside beats the robust Seiko Caliber 6206B automatic movement, a 26-jewel workhorse known for its durability. The movement presents very cleanly with a bright gold-tone rotor. Timegrapher testing shows the watch running between -2 and -7 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a brown leather strap featuring a crocodile grain pattern and contrasting stitching. It is secured by a gold-tone buckle that complements the case, providing a comfortable and classic fit on the wrist. Condition This timepiece is rated in good vintage condition. While the dial and hands are in excellent, highly attractive preservation, the case reflects its history with moderate surface wear and the specific mark noted on the upper bezel. The movement is performing exceptionally well for its age. Dimensions With a case diameter of 36 mm, this watch offers a perfectly balanced vintage presence. It sits discreetly and comfortably on the wrist, making it an ideal choice for formal or daily wear. Remarks The Seikomatic 6206-8040 is highly regarded by collectors for its successful integration of the day-date complication in a balanced, vertical layout. Finding one with such a clean dial and a movement running this accurately is a distinct pleasure for the vintage enthusiast. History The Seikomatic line was introduced in the early 1960s as Seiko's premier automatic watch collection, essentially serving as the automatic equivalent to the manual-wind Grand Seiko and King Seiko lines of the time. The 6206 series played a pivotal role in solidifying Seiko's reputation for producing high-quality, accurate, and beautifully finished automatic movements for the global market. /Second Vintage SKU: SEI-SMD-0005
