This clock comes from St Peter's Church, Martley, Worcestershire. Iron is generally used for the frames of turret clocks, but wood has occasionally been employed in English turret clocks. The working parts of the clock are made of iron, the driving weights are made of sandstone and the frame is oak. Timekeeping control is by a pendulum with an anchor escapement. This clock would have been made by a local blacksmith and a carpenter to the design of a profesional clockmaker.
