Model T's did not have optional clocks after about 1910. Phinney Walker clocks were the brand used by Stewart and Clarke in those days. A Stewart & Clarke clock would have been mounted in a brass bezel that matched the Stewart & Clarke speedometer on the same car.
Yours is later, perhaps from the 1920's. I think it may be specific to some car of that era judging by the styling of the bezel. It's definitely not from or for a Ford.
