Often, the internal mechanisms, such as the cogs, springs and other movements of the clock, are not faulty and are unaffected. Repair of a battery operated clock typically comes down to the batteries and the battery compartment, making the fix simple.
How do you fix a battery operated clock that loses time?
To remedy this, simply take down the clock, open up the battery compartment, and inspect the batteries to see if the batteries are worn out or rusted in any way. If there is rust, use an emery nail file to shave it off. Replace the batteries with fresh ones and your clock will start working like brand new.
Why has my quartz clock stopped working?

Do clocks need batteries?
Battery-operated clock movements are found in a wide variety of cases under many different names. Most movements operate for many years with no discernible problems other than the need to change batteries every year or so. But even new batteries are not going to help when a movement goes inexplicably bad. Replacing the battery-operated movement in your clock is a job that requires a new movement, a few tools and an ability to work with your hands.
What to do if your clock mechanism won't work?
If the mechanism will not work then simply replace it and are very cheap to buy, and will be probably screwed to the clock moulding with tiny screws to allow removal.
How accurate is a crystal clock?
Each is small but they do add up. For consumer grade crystals this is often about 100 ppm - parts per million. That means its 99.99% accurate. Which is usually quite good, esp. for twenty five cents. And most of them will be a lot better than that. 10–50 ppm is probably typical.
How does an electric toothbrush recharge?
My electric toothbrush gets recharged by the coil in its charging unit inducing a current in a coil in the toothbrush that is connected to the battery in the toothbrush handle. I doubt that your fireplace has little coils imbedded in it, but it might have little inclusions of something like steel wool fibers that just happen to resonate with the wavelength of the little signal that gets set off each time your electric clock releases a pulse of current to move the hands one tick forward.
How much does a crystal oscillator cost?
But, most crystal oscillators found in consumer grade equipment cost about $0.25 in bul k and not $1,000,000 like the clocks found in GPS satellites.
Why do RF oscillators use crystal oscillators?
Because they use a crystal oscillator for the timekeeping, in lieu of any other input (RF signals containing time information for example)
How accurate are oscillators?
and the accuracy is such that it gains or loses just a few seconds per day… typical accuracies are 20 seconds or so out of a million seconds. This can be caused by temperature changes and by voltage changes/fluctuations.
How do dry cells lose charge?
The clock will deplete the dry cell in the normal course of making the clock hands move. The dry cell could be depleted faster by having wires running out of your clock to supply current to some other gadget, but your clock is not set up that way. The only other way I know of for the battery to be discharged would be for it to set up an induced current is something nearby. The Faraday cage should keep that from happening.
How to clean a clock mechanism?
How to Clean the Clock Mechanism. Remove the cover over the mechanism. This differs from clock to clock. There may be lugs on the mechanism compartment that engage with the cover. If this is the case, push them gently aside with the blade of a screwdriver.

How Does a Quartz Clock Work?
The mechanism (also called the movement) or working parts in a quartz battery clock is a bit simpler than in a traditional wind-up clock.
Why won't my clock run?
If the clock still won't run, the cogs inside may have grime on the teeth or axles. Even though there's a cover on the mechanism compartment, in humid, dirty conditions (e.g., in a bathroom) dust and mildew can manage to get in. So you need to do some cleaning. The solenoid in the clock only produces a tiny amount of torque or twisting force to turn the little rotor. Any grime on the pins of this rotor can produce enough friction to stop it from turning.
How does an oscillator work?
The output of the oscillator drives an electromagnet that acts on a tiny magnetic rotor, flipping it half a turn every second. The rotor has gear teeth that mesh with a train of other gear wheels and this eventually turns the hands of the clock.

How to get at the mechanism of a clock?
To get at the mechanism, you need to remove the cover on the compartment that holds the gears and electronics. Inside the clock, an electromagnet moves the little blue magnetic rotor half a turn every second. This turns the other gears. This tiny rotor magnet is about 3/8" or 10mm long.
Troubleshooting Quartz Clocks 101: Common Issues, Easy Fixes
It’s likely we all own one – a decorative, stylish clock that adorns our home but never really tells the time correctly. It may have stopped completely or begun to lose time several years ago, and somehow we have just never gotten around to fixing it. Quartz clocks can be excellent design features, even more so when they’re working.
Give Your Hands a Hand
Another thing that may be working against your clock is its hands. If the hands are rubbing up against each other or the clock face, it will take more torque to move them. Having to use that kind of power consistently will, at best, slow your clock and quickly drain your battery. Remove the clock crystal and look at the hands.
Clocks Movements Get Dirty, Too
After completing all of the above steps and your clock still doesn’t work, consider having it cleaned professionally. The same dust and dirt that regularly collect over your tables, countertops, and other furniture can just as easily make their way into that Bering wall clock you love so much.
