Brand: Seiko Model: Seikomatic Reference Number: 6206-8010 Serial Number: 6304335 Movement: Automatic Caliber 6206B Dial: Silver Sunburst Crosshair Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1966 Condition: Excellent vintage condition. The watch presents beautifully with sharp case lines and a well-preserved dial. Dial and Hands The silver sunburst dial features a striking crosshair design that divides the face into four quadrants, adding depth and symmetry. It is adorned with multi-faceted applied block hour markers that catch the light beautifully. The polished dauphine hands are sharp and distinct. A framed full-day window is positioned at 9 o'clock, with the date window located at 3 o'clock, creating a unique and balanced horizontal layout. The applied Seiko logo and printed "Seikomatic Diashock 26 Jewels" text remain crisp and legible. Case and Crystal The stainless steel case measures 36 mm in diameter and features the signature hidden crown at the 4 o'clock position, a design choice that streamlines the case profile for a dressier appearance. The case retains strong lines and defined lugs. The snap-back caseback features the iconic dolphin emblem and crown engraving, signifying its water-resistant heritage, along with clearly visible reference and serial numbers. The acrylic crystal is domed and clear, providing excellent visibility. Movement Powered by the robust Seiko Caliber 6206B automatic movement, this 26-jewel mechanism features Diashock shock protection. The movement is finished with gold-toned plating on the rotor and bridges, creating an attractive visual contrast. Timegrapher testing indicates a rate of approximately +38 to +41 seconds per day, which indicates a healthy movement offering reliable vintage performance. Strap The watch is fitted with a black leather strap featuring contrasting tan vintage-style stitching near the lugs, secured by a polished steel buckle, complementing the vintage aesthetic of the piece. Condition This timepiece is in excellent vintage condition. The dial is remarkably clean with only very faint signs of aging visible under close inspection. The stainless steel case shows honest vintage wear with light surface scratches but no major dents. The caseback engravings are legible, though the central dolphin medallion shows some smoothing consistent with age and wear. Dimensions Diameter: 36 mm (excluding crown) Lug width: 19 mm Remarks The Seikomatic 6206-8010 is a definitive example of mid-century Seiko design, offering a refined aesthetic that rivals Swiss contemporaries of the era. Its combination of the crosshair dial, hidden crown, and separate day-date windows makes it a standout dress watch that exudes 1960s charm. History Introduced in the early 1960s, the Seikomatic line was Seiko's premier automatic luxury tier, serving as a technical and design precursor to the automatic Grand Seiko models. The 6206 caliber was a reliable high-jeweled workhorse of the era. The unique "Weekdater" layout, separating the day and date, became a signature look for Seiko's business watches during Japan's rapid economic growth in the 1960s. / Second Vintage SKU: SEI-SMD-0008
