We made these clocks as promotional items for our retailers and to supply to military bases for use in the mess but interest has been so great we have decided to retail them too. The wall clocks are 17 x 17 x 4 cm (6.5\" x 6.5\") in a strong and robust High Impact Polystyrene case. They have a genuine glass lens and a high accuracy quartz movement, They are supplied ready to go and complete with battery. If you want something different for your home or office this has to be it!
