Vintage Audemars Piguet & Co. Open-Face Pocket Watch

This is a significant horological piece representing an early 20th-century open-face pocket watch by the prestigious Swiss manufacture Audemars Piguet & Co. The watch features a slim, circular case, likely constructed of white metal or steel with gold plated or solid gold accents seen on the inner bezel and crown assembly. The dial exhibits a textured, brush-finished silver-tone surface that has developed a visible and heavy aged patina, including spotting and oxidation consistent with a mid-century origin. It features applied gold-tone Arabic numeral hour markers in a classic serif font and an outer 'pearl' minute track. The handset consists of elegant, open-tipped cathedral or Breguet-style hands in a matching gold finish. The signature 'AUDEMARS, PIGUET & CO.' is printed clearly below the 12 o'clock position. The watch is topped with an unusual hexagonal-shaped bow and a knurled winding crown at the 12 o'clock position. Condition-wise, the timepiece shows significant surface wear, scratching on the crystal, and heavy tarnishing on the dial surface that suggests moisture ingress or natural aging of the lacquer. Despite the condition issues, the high-quality craftsmanship is evident in the applied indices and precise brand typography, typical of the Art Deco or post-war era production.
