The Palumbo Tompion is the earliest recorded Phase 3 spring clock, and the only one with a month-going movement. The only other extant month-going Tompion spring clock is No. 187, a Phase 2 example, the property of the National Trust at Lyme Park, Cheshire.

As with his month-going longcase movements, for this month-going spring clock, Tompion transposed the wheel trains with the going on the left and strike on the right.
