Late 19th or Early 20th Century Black Mantel Clock with Corinthian Columns

This is a classic architectural-style mantel clock, often referred to as a 'Black Mantel' or 'Adamantine' clock, likely dating from 1880 to 1910. The case is constructed with a dark finish, possibly black-lacquered wood or Adamantine veneer, meant to mimic slate or marble. It features a rectangular tiered base and a pediment top adorned with an ornate bronze or brass-toned scrolled applique. The central clock face is flanked by two fluted Corinthian-style columns with metallic-finished capitals and bases. The round dial features an ivory-colored chapter ring with Arabic numerals, an ornate brass-toned center disc with scrolled patterns, and a decorative pressed metal bezel. Two winding holes are visible, suggesting an eight-day movement with a chime or gong striking mechanism. Regarding condition, the piece shows significant age-related wear; there is visible dust accumulation, surface grime, and oxidation on the decorative metal elements. Small chips and abrasions appear on the black finish, particularly along the sharp edges of the base and pediment. The glass covering the dial appears intact, though the hands show slight signs of surface patina. No specific maker's mark is visible on the front, but this style was characteristic of major American manufacturers such as Seth Thomas, Gilbert, or Ansonia. The craftsmanship is typical of high-volume Victorian-era production, emphasizing neoclassical architectural aesthetics.
