Citizen “Auto Dater 7” 19-jewel automatic wristwatch. According to the serial number, this piece was manufactured in May 1964, making it an early example from the first year of production. Introduced in 1964, the Auto Dater 7 series was the first Japanese watch to feature Citizen’s original Jet movement with an outer ball-bearing rotor – well known for its distinctive winding sound. This particular piece is the 19-jewel version, equipped with 40M water resistance for practical daily use. The dial is finished in a sunburst silver tone, with applied bar indexes and dauphine hands for a timelessly elegant look. Its separated calendar layout, with the day at 12 o’clock and the date at 3 o’clock, reflects Citizen’s characteristic design of the era. The screw-down caseback further enhances its durability and water resistance. The watch comes with a brand new leather strap, ready to wear. A significant piece marking the milestone of Japanese vintage watchmaking. The watch is in working condition, but accuracy, power reserve, and water resistance are not guaranteed.
