Vintage Elgin Octagonal Ladies' Wristwatch

This is a vintage ladies' wristwatch produced by the Elgin National Watch Company, likely dating from the 1920s to early 1930s (Art Deco period). The watch features a characteristic octagonal (eight-sided) case made of yellow gold-filled or rolled gold metal. The bezel is elaborately decorated with a dense floral and scrollwork engraved pattern, a hallmark of Art Deco feminine horology. The dial is a cream or lightly aged champagne color, marked with 'ELGIN' below the 12 o'clock position. It utilizes black Arabic numerals and heat-blued steel hands. The crystal is significantly compromised, showing heavy yellowed residue (possibly old adhesive or sealant) and surface scratching over the 9 and 10 o'clock area. The case shows moderate wear with some loss of plating on high-relief edges and around the lugs. It is attached to a vintage gold-toned expansion-style bracelet with a twist-link design. The knurled crown appears to be original. The overall condition is fair to poor due to the dial contamination and crystal damage, needing professional restoration to determine movement functionality.
