Elgin Art Deco Decagonal Pocket Watch

This is a vintage Elgin National Watch Company pocket watch featuring a distinctive Art Deco style from the early 20th century, likely dating between 1920 and 1935. The watch is housed in an attractive 10-sided (decagonal) case crafted from a silver-toned metal, possibly white gold fill or nickel-chrome. The case edges and bezel are intricately engraved with a textured foliate or geometric pattern characteristic of the period. The dial is a silvered or champagne-colored metal with a complex dual-finish: the center is embellished with an elaborate scrollwork engraving, while the numbered track has a brushed finish. It features bold Arabic numerals in a stylized font and a dedicated sub-dial for seconds located at the 6 o'clock position. The hands appear to be blued steel or a dark finish, with a cathedral or spade style. The crown is located at the 12 o'clock position with an arched bow. Regarding condition, the watch shows visible patina and oxidation on the dial and case. There is notable wear and light scratching on the crystal and case bezel. The movement state is unknown, but the overall craftsmanship suggests a high-quality decorative piece from a prominent American manufacturer.
