Perfect decorative wall clock for dining rooms, living rooms, family rooms, bedrooms, study room, kitchen, office, or conference room. Easy to read - large black bold numbers on a white background for easy viewing. The sturdy frame and glass lens prevent dust from entering the dial. Quiet frequency scanning and precise quartz movement ensure accurate timing and a good sleeping and working environment. Battery operated and easy to install - powered by AA batteries (not included), we do not recommend using high load batteries. The rear groove design is easy to install, just thread a small nail through the plastic hook, and it will hang firmly on the wall in a few seconds.
