Offered in this auction by Second Vintage This is a remarkable example of mid-century Japanese horology, showcasing the elegance and technical prowess of Seiko during the 1960s. The Seikomatic series played a pivotal role in establishing Seiko as a global leader in automatic watchmaking, serving as the foundation for the brand's future high-end automatic tiers. With its distinctive day-date layout and sophisticated crosshair dial, this piece captures the essence of the "Weekdater" era. Brand: Seiko Model: Seikomatic Reference Number: 6206-8010 Serial Number: 5702875 Movement: Automatic Caliber 6206 Dial: Silver sunburst crosshair Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1965 Condition: Good vintage condition, showing honest signs of age on the dial periphery and normal wear to the case, while running reliably with healthy amplitude. Dial and Hands The watch features a sophisticated silver sunburst dial characterized by a distinct crosshair design that divides the face into quadrants. The layout is unique to this era, featuring a full day window display at the 9 o'clock position and a date window at 3 o'clock. The applied block indices are multi-faceted to catch the light, complementing the sharp dauphine hands. The dial shows signs of vintage aging, particularly along the outer edges between the 4 and 7 o'clock positions, where some patina and degradation have occurred over the decades, adding to its authentic character. Case and Crystal The 36mm stainless steel case features the classic grammar of design lines with strong, angled lugs. A defining feature of this model is the recessed crown positioned at 4 o'clock, designed to sit flush with the case to emphasize the automatic nature of the movement, as manual winding was deemed unnecessary. The caseback displays the iconic Seiko Dolphin (or Sea Lion) emblem, which remains visible along with the serial and reference numbers. The case shows moderate surface scratches consistent with a watch from 1965, preserving its original geometry. Movement Powering this timepiece is the robust Seiko Caliber 6206 automatic movement, featuring 26 jewels and Seiko's Diashock protection system. This movement is a workhorse of the era, known for its efficiency and durability. The movement presents well visually with its gold-tone rotor. Based on timegrapher testing, the watch is currently running between -10 and -19 seconds per day, which indicates healthy movement function within acceptable vintage tolerances. Strap The watch is fitted with a black leather strap featuring white contrast stitching. The strap is in excellent condition and provides a sporty yet elegant contrast to the silver dial, making it ready for immediate wear. Condition This timepiece is in good vintage condition. While the dial shows visible patina and aging around the periphery, the central text and crosshair lines remain crisp. The stainless steel case retains its shape without signs of over-polishing, showing honest wear. The movement is functioning correctly and the timekeeping is solid for a 60-year-old mechanical instrument. Dimensions With a diameter of 36mm excluding the hidden crown, the watch offers a classic vintage proportion that sits comfortably on a variety of wrist sizes. The lug-to-lug length ensures a balanced presence, suitable for both formal and casual attire. Remarks The Seikomatic 6206-8010 is often celebrated by collectors for its unique "Weekdater" configuration and the hidden crown design. It represents a specific moment in Seiko's history where practical luxury was becoming accessible. The crosshair dial variant is particularly desirable for its added visual depth and mid-century aesthetic. History Introduced in the early 1960s, the Seikomatic line was Seiko's upper-mid-range automatic offering, sitting just below the Grand Seiko and King Seiko lines. It was instrumental in popularizing automatic movements in Japan and abroad. The use of the Dolphin icon on the caseback symbolizes the water-resistant capabilities touted during this era, marking Seiko's commitment to durability alongside elegance. This specific example, produced in July of 1965, is a tangible piece of that rich history. Payment and Shipping Payment must be completed within 1-3 days after purchase.
