Smiths, then called as S. Smith and Sons (Motor Accessories) ltd. Entered the domestic clock market and formed a new company, Smiths English Clocks Ltd, as the clock and watch division with cricklewood as the main factory in 1931.
In 1956 Smiths offered clocks with the new floating balance movement invented by Hettich in Germany and licensed to Smiths. In 1960 they offered a smaller version to their own design, which was widely used as regulation was easy and precise . The floating balance had advantages over older escapements It is robust and less sensitive to disturbance, as for example when dusting, or to being out of level.
In 1970 they introduced a range of clocks using the Tensator movement in which a special spring provides constant torque and potentially better timekeeping.
