▼Management Number▼ 0426 344 ■Product Description This is a vintage model that follows in the footsteps of the "Business Week (Seikomatic)" series, which Seiko developed as a high-end model in the 1960s. It features a distinctive full-spelling display of the day of the week at the 12 o'clock position, and its intellectual design, a fusion of advanced technology and playfulness from that era, is its charm. The battery-free automatic movement still keeps time perfectly, allowing you to experience the charm unique to mechanical watches. The combination of the streamlined case form and silver dial exudes a timeless beauty that has not faded even after more than half a century. It is a highly popular antique Seiko, a masterpiece that evokes the golden age of Japanese watchmaking. 【Detailed Specifications】 Brand: Seiko Model Number: 6206-8040 Movement: Automatic / Working Gender: Men's Serial Number: 6209269 (Estimated to have been manufactured in February 1966) Remarks: Full-spelling day of the week display, Vintage item We will ship via DHL or FEDEX to arrive within 5 days.
