Vintage Zenith Automatic Rectangular Wristwatch

This is a vintage Zenith automatic wristwatch, likely dating from the 1960s to early 1970s. The watch features a distinctive rectangular gold-toned case, possibly 14k or 18k gold filled or solid gold, with sharp, chamfered lugs that reflect the geometric design aesthetic of the mid-century era. The dial is a champagne or light gold sunburst finish, displaying applied gold baton hour markers and a centered Zenith star logo above the brand name. Below the brand name, the text 'Automatic' and 'DATE' is visible. A notable feature is the trapezoidal date window positioned between the 4 and 5 o'clock markers, a characteristic layout for certain Zenith movements of this period. The hands are thin gold batons with a matching central seconds hand. The crystal appears to be acrylic and shows minor surface scratches consistent with the age of the piece. The case displays some light patina and micro-abrasions, particularly on the bezel edges, but retains its structural integrity. It is paired with a cognac-colored leather strap that shows slight wear at the lugs. The overall craftsmanship suggests a high-quality Swiss mechanical movement, likely from the reputable 25xx series, known for durability and precision.
