Wall Clocks

We've got so many wall clocks, we've split them up to make them easier to look through. If you are looking for analog (dial) wall clocks bigger than 14 inches, or digital wall clocks with digits larger than 2 inches, please see the large clock section. Analog wall clocks 14 inches or less are split into the categories below. We also have a great selection of atomic wall clocks, quartz wall clocks and wood wall clocks. For an explanation of wall clock technologies, please scroll down.

Wood Wall Clock
This is our wood wall clock selection. We have wood atomic wall clocks, and conventional wood clocks, in a variety of finishes.

Atomic Wall Clock
Here is our atomic wall clock selection.

Large Wall Clock
Our large wall clocks have one thing in common, they are over 14 inches in diameter. Some of these large wall clocks are Atomic, some are auto-setting, and some are quartz analog.

Quartz Analog Wall Clocks
The clocks in this section all have quartz analog movements. Quartz Analog clocks have reasonable accuracy, at a reasonable price. Clocks in this section range in diameter up through 14 inches.

Auto Setting Analog Wall Clocks
The clocks in this section all have self setting movements. They range in diameter up through 14 inches.

School Clock
Many schools are going with atomic clocks as school clocks. Atomic clocks will all read within a fraction of a second of the same time, and they are far less expensive than synchronized school clocks that require expensive wiring.

Outdoor Clock
An outdoor clock is designed to tolerate moisture and wider temperature ranges. Some outdoor clocks are weatherproofed well enough to be out in the rain, some outdoor clocks are not. Many outdoor clocks also have thermometers in them.

Quartz wall clocks: Quartz wall clocks, like any quartz clock, has it's accuracy controlled by a quartz crystal. A precisely trimmed quartz crystal is used to generate an electrical timing signal that regulates the speed of the clock. Quartz wall clocks may gain or lose around one second per day, and the drift rate may depend somewhat upon temperature.

Auto setting wall clocks: Auto-setting wall clocks are a relatively new technology. They are available under a number of names, depending on the manufacturer. Auto-setting wall clocks are built with a quartz crystal to regulate speed, and a built in integrated circuit that knows the approximate time, and the date. Although they can gain or lose time like any quartz clock, they have one advantage. They know about, and will automatically adjust for daylight savings time.

Atomic wall clocks, or Radio Controlled wall clocks: The United States Government National Institute of Standards and Technology maintains a radio station, WWVB, in Ft. Collins, Colorado. This radio station transmits highly accurate time information. Atomic, or Radio Controlled clocks receive this signal when they can, and set themselves. These will maintain time accurate to a fraction of a second as long as they are placed in a location where they can receive the signal. Like any radio receiver however, they may not be able to receive the signal if they are in a building with a lot of steel in the structure, near computers or cordless phones that may generate interference, or if the weather is unsuitable. Please note. The signal they receive does not propagate well during the day. That's the nature of the signal, not the clock. These clocks are designed to catch the signal when they can, generally in the middle of the night, calibrate themselves, and then run quite accurately for days until they can catch another signal. When you first put in the batteries, they will most likely not set themselves until the middle of the night. The analog clocks generally tick for a few seconds, advance to 4:00, and wait. The digitals display various things while they wait. That's normal. By morning, weather permitting, it should be correct.
