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.

Smiths formed a subsidiary company called Synchronous Electric Clocks to produce these clocks as the first models carry this name.

Prior to this date calottes had been exclusively of foreign manufacture.

Also that year, Smiths introduced the Batriclock which was intended for areas where the synchronous clock could not be used.

They said it was the remarkable combination of a synchronous electric movement with the essential elements of a fine precision lever escapement.

If the electric supply failed the clock would run for up to six hours and rewind when the power returned.

Apparently the synchronous motor also corrected the mechanical time train at intervals.

Also the introduction by Smiths of a calotte clock with an alarm movement.

Timepieces, Alarms, Striking, Chiming, Wall and Marine Clocks.

Master Clock Systems, Time Recorders and Turret clocks; also Pocket, Wristlet and Stop Watches.

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.

This movement had three hairsprings which served to carry current to the coils.
