This is a model from Seiko's Five series, the "Sportsmatic Deluxe," which was sold as a higher-end model. Its features include the five main functions of the "Five" series (shock resistance, automatic winding, date display, day of the week display, and 30m water resistance), plus a crown-recessed design that prioritizes styling, without a manual winding function. It's also characterized by its efficient winding even with just the movement of the wrist, reflecting Seiko's confidence in its automatic watches at the time. The indices and the "5" logo are applied, and the day-date display is positioned at the 3 o'clock position. Manufactured in 1964, the year of the Tokyo Olympics, it was a high-end product that cost a considerable 12,000 yen at the time. In addition, the gold-plated bracelet type was produced in small numbers and is extremely rare. It is a working item, but the date change button has a defect. Automatic winding is possible! Please consider it as a junk item!!
