One of the most important factors when dealing with wall clocks is the fixing of them to the wall. Most will hang from the wall on a screw, fixed into the wall with a rawl plug. Wall clocks do not just sit immobile on the wall. They are under stress and strain whilst being wound and set to time as well as polishing and dusting etc. Therefore the screw needs to be large enough and strong enough to withstand this. In addition the screw should be screwed into the wall with the screw head pointing upwards to allow the clock to slide down the shank of the screw and nestle against the wall. Whilst the door or bezel is open for winding and hand setting some wall clocks will tip side ways on the wall. Some clocks have an extra bracket to allow them to be screwed to the wall top and bottom. Others have thumbscrews on flat brackets at the bottom rear of the case. These are pointed and should be screwed into the wall so that they dig in to the wall slightly to prevent the case tipping. Another method is to glue small pieces of cork to the back of the clock case facing the wall to provide extra friction.
Some wall clocks such as Vienna regulators will also have lines and weights. The winding of these follows the same principle as for the eight day longcase above. Others such as lantern clocks, cuckoo clocks or hooded wall clocks can have rope or chain. These are wound in the same manner as for a thirty hour longcase clock. Others are spring driven, and are usually wound by inserting a key into the winding holes on the dial. As with all clocks it is essential that the winding key is a good fit on the winding square. These clocks can have one, two or three winding holes and it is essential that all three are wound.In the case of an eight day clock, once a week and a thirty hour clock once a day. Most wall clocks will wind clockwise. However this is not always the case. Some can wind anti clockwise in all winding holes or in the case of American wall clocks the left and right hand winding holes will wind in different directions. For instance a spring wound American wall clock will wind clock wise in the left hand winding hole and anti clockwise in the right hand winding hole. For a weight driven American wall clock this will be reversed.
