Auditory and projection clocks can be used by people who are blind or have limited vision. There are also clocks for the blind that have displays that can be read by using the sense of touch. Some of these are similar to normal analog displays, but are constructed so the hands can be felt without damaging them. Another type is essentially digital, and uses devices that use a code such as Braille to show the digits so that they can be felt with the fingertips.
Whether you’re styling an accent wall or rounding out your decor, a retro-inspired wall clock like this one draws the eye while adding some utility to your ensemble. The large numbers make this clock easy to read, and with quartz movement, it features a more accurate reading.

“Love how simple this digital timer is. I travel a lot, and it’s small enough to put in my purse. The off button is convenient because it keeps the buttons from being pressed while stored away and conserves the battery, but when you turn it back on, your setting are stored so no need to reset [each] time. … [There’s just the] clock, alarm, snooze, on/off. The smaller and simpler the better when I’m traveling.”
In a typical verge-and-foliot escapement, the weighted rope unwinds from the barrel, turning the toothed escape wheel. Controlling the movement of the wheel is the verge, a vertical rod with pallets at each end. When the wheel turns, the top pallet stops it and causes the foliot, with its regulating weights, to oscillate. This oscillation turns the verge and releases the top pallet. The wheel advances until it is caught again by the bottom pallet, and the process repeats itself. The actions of the escapement stabilize the power of the gravitational force and are what produce the ticktock of weight-driven clocks.
A. Like many items today, the amount you’ll pay for an alarm clock depends on how much technology you want layered onto it. If you desire nothing but a simple analog alarm clock that rouses you with a single tone, you could spend as little as $10. A slightly more sophisticated clock radio might cost $20 or so. If you want a deluxe digital alarm clock with screen projection, Bluetooth capability, MP3 player, or other cool features, you’re looking at a price of anywhere from $40 to $90.
“Great alarm clock for the price. Gigantic numbers for my old eyes. Very basic, easy to set, just what I wanted. Alarm is loud even on low [with] an awful sound that would wake the dead. But that sound makes me get right up, so it does exactly what it’s supposed to do. If you want a soft gentle caress to wake you, get something else, but this is a good alarm and easy to use.”
