Antique French Black Slate Marble Clock Garniture Set Mercury Pendulum Running

This 19th century antique French black slate and green marble mantel clock garniture set features a large architectural case with twisted brass columns, open Brocot escapement dial, glass front viewing door, and an authentic mercury pendulum. Standing as a substantial table piece, the clock set comes complete with its original pair of matching black marble side tazzas and a winding key. The mechanical movement runs when wound, though the chime function requires service, and there are small chips and edge wear to the marble and slate case visible throughout. Please inspect all photographs carefully for exact dimensions, physical wear, chip locations, and movement details before purchasing.
