had mechanical movements, powered by an electric remontoire. A low power drive spring would be wound every few minutes by a plunger in a solenoid, powered by the vehicle's service battery and activated by a switch when the spring tension got too low. Such clocks were, however, notoriously inaccurate, typically being made as cheaply as possible. Many Rover (P4 to P6), Ford (Mk1 Escort, Mk2 Cortina, and Mk1 Capri GT/RS), and Triumph (Dolomite, 2000/2500, and Stag), as well as some Jaguar (S2 E-type), Daimler (DS420), and Aston Martin (V8) cars were fitted with Kienzle clocks that were wound by such electric remontoires.
