Chelsea 8 1/2" Library Clock for Tiffany & Co., New York. Ships Bell. Library clocks are exceedingly rare in any dial size. 8 1/2" dial examples are almost never seen. Note the symmetrical base with fine beading and the unusual bezel and back flange with coin edges. Library clocks are attractive from any angle. Serial number 70897 on the movement and the wood insert in the bottom of the case dates the clock to 1911. The dial has been resilvered. The case has been polished and lacquered. The movement has been serviced. A fine example of a very desirable Chelsea shelf clock.
