Vintage Sturdymaid Swiss Art Deco Ladies' Wristwatch

This is a diminutive Art Deco era ladies' wristwatch, likely dating from the 1920s to early 1930s. The piece features a characteristic tonneau-shaped (barrel) watch head made of a silver-toned metal, possibly white gold-filled or nickel-plated, which exhibits intricate floral and geometric engraving along the sides and integrated lugs. The rectangular dial is finished in a metallic silver or champagne tone with a central textured or sunburst motif, bordered by bold, black stylized Arabic numerals typical of the period. The hands are dark Breguet-style or catheter hands. A distinctive onion-style winding crown is positioned at the 3 o'clock mark. The watch is presented as the watch head and partial attachment linkage, missing its original cord or ribbon strap. Regarding condition, there is notable mechanical patina and surface wear consistent with age, including some oxidation on the metal casing and slight discoloration or 'foxing' on the dial plate. The brand 'Sturdymaid' indicates a Swiss-made movement housed in a case likely produced for the American market during the height of the Art Deco movement. The craftsmanship reflects the era's focus on jewelry-like utility for women's timepieces, emphasizing decorative engraving over pure functional minimalism.
