Wall & Mantel Spring Driven Clocks
A spring driven clock is powered by metal springs that are wound either daily, weekly, every two weeks or monthly. They are generally either mantel or wall clocks. Some floor clocks are spring driven, but that's not the norm. You can tell if your clock is spring driven because it will have one, two, or three holes which a key can be inserted into to wind the clock and you won't see any weights inside the case.

-
Wind it on a regular basis depending on if it's a one, eight, 14 or 31 day clock
-
Your wrist naturally, makes a half turn with each wind. Keep track of how many turns you make. For example, many 8 day clocks require 14 half turns per week.
-
With each wind, keep pressure on the key until you don't feel any "push-back" from the spring. Then reset your hand and take the next half wind. This prevents the "click" from wearing.
-
It is a misconception to "overwind" a clock. For most clocks, the spring is meant to be wound tight and to open up as the clock runs. If a clock is fully wound and won't run, that usually means it needs to be serviced.
-
Never move the clock with the pendulum on. It it can't be removed easily, secure the pendulum so it will not move. Failing to do this can either break the suspension spring that it hangs on, or more likely it will put the clock "out of beat." If the beat or tic toc is off enough the clock won't run.
-
A clock that has been serviced properly, should be set up to run level. Before installing the pendulum, level the case.
-
Clock timing can vary depending on temperature, humidity, and elevation. Most likely you will need to tweak the timing of the clock. Antique spring driven clocks that are with 5 minutes accuracy for a week, is normal. When winding, adjust the time accordingly.
-
A general rule of thumb when winding a clock is to move the minute hand clockwise stopping whenever the clock wants to strike. After it's finished striking continue until the next striking or the proper time has been reached.
-
Most oils today will maintain their viscosity for at least 10 years, so they should not need oiling every year. In fact, too much oil will have an adverse effect on the clock.
-
If a clock has been acting a certain way for years, and suddenly starts acting "strange" such as the timing is off or the chimes are slow, then that's an indication that it needs servicing. We can give you a free estimate for the clock repair.
