Clocks are machines, just like your car. But unlike your car, clocks run all the time. Literally 24/7. So it's little wonder that in 5 years' time, your clock's fastest moving gear has spun around more than 2.5 million times! Homes can be dusty places, even though you don't usually see the dust in the air. And dust is abrasive stuff. It gets into the movement and gets into the pivots causing wear. You need to have your clock serviced to make sure that wear doesn't become excessive. If it does, the wear will eventually stop the clock as gears get misaligned and friction overcomes the power the clock can provide.
Clock repair can be a tricky business. There are lot of moving parts! And when it's done, everything has to not only function, but it has to look good, too. Also, every clock has a history that began when it was manufactured. In most cases, you don't want to disturb that history. Restoration should be gentle. Nick of Time will repair problems with your clock and preserve the clock's history.
