There are 2 Killinchy Clock Designs. The Traditional Farmhouse Clock designed by Joseph Thompson and The Model 3K Clock which has a celtic design . Both are powered by gravity and with the long pendulum taking a full second to swing in each direction, an irish farmhouse clock will provide a focal point in any home or office. There is no need for lubrication in the clock movement. So precise is the crafting that each part of the wooden mechanism is free moving and interchangeable. As such, routine maintenance is unnecessary. Wear is minimal and there is no doubt that Killinchy Clocks will still be keeping time a hundred years from now.
