Vintage 60s Citizen Auto Dater 7 520 21J Automatic Day Date 37.5mm Gold Watch

About this watch

Day at twelve, date at three, a fluted gold-tone bezel and the small "7" emblem above six: this layout identifies Citizen's Auto Dater "Seven" of the mid-1960s at a glance. The silver-white dial has applied gold-tone baton markers, a framed day window at 12 (with Sunday shown in red) and a framed date window at 3, and is signed Citizen Auto Dater, 520, 7, 21 Jewels.

The 37.5mm gold-plated case is large for its period, with a finely fluted bezel and sharp lugs. The screw-down steel caseback is marked Citizen Auto Dater with the 7 emblem, Parawater and Star. Inside is a Citizen automatic movement with 21 jewels, its rotor signed "Citizen 21 Jewels".

Brand heritage

Citizen traces its roots to the Shokosha Watch Research Institute, founded in Tokyo in 1918. In 1924 it produced its first pocket watch, named "CITIZEN" by the mayor of Tokyo, Shinpei Goto, and in 1930 Citizen Watch Co. was established. In the 1960s Citizen's Auto Dater line brought automatic winding and calendar functions to everyday buyers, and the "Seven" day-date models of the mid-1960s were its answer to Seiko's Sportsmatic 5, leading on to the later Crystal Seven family.

Condition

Honest vintage condition. The dial shows spotting and age-related tonal changes, while the case and caseback show scratches, plating wear and general surface marks consistent with decades of use. The strap also shows wear. As with any vintage watch, it is sold as a collectible, is not guaranteed water resistant, and its timekeeping may differ from a modern watch. Please check all photos carefully as they are part of the description.
