About the Seth Thomas “Chime Clock No. 55” Clock
Introducing the “Chime Clock No. 55” by the Seth Thomas Clock Co., a noteworthy mantel clock produced around 1914-1915. This timepiece, characterized by its 8-day movement and 4-bell Sonora chime, stands at a height of 9.5 inches, making it the smallest Sonora chime model manufactured by Seth Thomas.
The clock is housed in a mahogany case with an alligatored original finish, although some minor scratches are present. The silvered dial, while relatively free of scratches, has undergone tarnishing. The dial plate may require tightening upon disassembly. The original hands remain intact.
The clock’s striking mechanism and movement are marked with stamps 89Z and 90I respectively. Notably, this model is extensively documented in various editions of Tran Ly’s books on Seth Thomas clocks. Despite being in storage, the clock retains its charm and, with a proper cleaning, can produce its tune effectively. The beveled glass in the bezel remains undamaged, adding to the overall appeal of this collectible piece.
