This Farringdon wall clock has been designed with 3D effect metal roman numerals to make a statement in any home. Silent Tick. Batteries not included, require 1 x AA battery. Insert battery as indicated in the battery holder - the movement will be damaged if the battery is not properly inserted as instructed. We recommend replacing the battery once a year, even if the clock is still running. Remove the battery when the clock is not in use. Set the time by turning the dial on the movement.
