Vintage Waltham Open-Face Pocket Watch with Decagon Case

This is a vintage American pocket watch manufactured by Waltham, likely dating to the 1920s or 1930s based on its Art Deco design influences. The watch features an open-face configuration with a distinct decagon (ten-sided) bezel and case, which is heavily embellished with an engraved scrolling or foliate pattern along the edges. The dial is multi-textured, showcasing a central circular section with vertical pinstripe guilloché engraving. It employs stylized gold-tone Arabic numerals applied to an outer silvered track. A sub-dial for seconds is located at the 6 o'clock position, featuring fine concentric circular graining. The hour and minute hands are dark blue or black 'cathedral' style, providing high contrast. The 'Waltham' brand name is visible in a small cartouche below the 12 o'clock marker. The case material appears to be gold-filled or brass with a gold-tone plating, showing signs of aged patina and minor surface wear. The crystal appears intact but may have light scratches commensurate with age. The crown at the top is fluted with an ornate bow, typical of dress watches from the early 20th century. This piece reflects high-quality American industrial craftsmanship from the peak of domestic watchmaking.
