Vintage Art Deco Rectangular Ladies' Wristwatch

This is a vintage ladies' wristwatch head from the Art Deco era, likely dating from the 1920s to the 1930s. The watch head features a distinctive rectangular or tonneau-shaped case with clipped corners. The dial is a vibrant gold-tone with an intricate textured or etched pattern throughout the center. It displays stylized Arabic numerals positioned vertically on the right side, a hallmark of early deco designs. The case itself appears to be made of a silver-toned metal, possibly white gold filled, platinum-plate, or stainless steel, exhibiting a thin bezel that frames the ornate dial. Two dark-colored hands are present, showing slight misalignment. There are visible signs of aging including surface scratches on the crystal and metal casing, as well as significant tarnishing and some possible mechanical separation between the case and the internal movement components. The watch head is currently detached from its strap, though a separate expandable metal bracelet with a safety chain is visible in the background. No maker's mark is immediately legible on the face, but the craftsmanship suggests a mid-tier production from the early 20th century.
