The 43003 Westclox Big Ben Twilight Alarm Clock features authentic 1950's traditional styling plus a couple of modern features that weren't around back then. This analog clock with three-hand display is powered by 120Vac, 60Hz current from a wall outlet. Unlike most clocks of the '50s, though, this one has battery backup so it keeps time and sounds its alarm (if set) even during ac power outages. Also, the dial stays constantly lit (except during ac outages) for easy viewing even in the dark. True to its heritage, the Twilight clock's alarm is a real bell, not the usual electronic beep of today. But like many clocks of today, the alarm has a repeat snooze function. With its bright yellow-green color, the Twilight is sure to liven up your bedroom (or anyplace else you decide to use it). Super-simple to set and use, the Twilight alarm clock fits perfectly on a nightstand, dresser, table, or shelf.

The 43003 Twilight clock is really easy to use. You insert the two-prong polarized plug into a 120Vac, 60Hz outlet and then set the current time and alarm time by means of separate rotating knobs on the back of the clock. Be sure to turn them in the direction indicated so as not to damage the clock. The movement in the Twilight is a conventional analog quartz movement. Thus, this clock is not "atomic" and does not adjust automatically for Daylight Saving Time, but it is extremely accurate. If you want the Twilight's timekeeping and alarm functions to continue to operate during ac power outages and when you unplug it to relocate it, you can insert two AA batteries into the compartment on the bottom of the clock. Please be aware that the dial light turns off when the clock is operating on battery backup.

After you set the alarm pointer to the desired alarm time, you turn the alarm on by sliding the ALARM switch on the back of the clock to ON. A genuine ringing bell sounds when the set time is reached and continues to ring for about 35 minutes unless you silence it earlier. On this clock, there are two ways to do this. You can do it the old-fashioned way by sliding the ALARM switch to OFF, which turns the alarm off entirely until you reset the switch to ON. Or, you can use something that wasn't available (or at least common) on clocks of the '50s, and that is the Twilight's available repeat snooze function. Pressing the SNOOZE button on the top of the clock while the alarm is sounding silences it for about 4 minutes, after which the alarm sounds again. You can use the snooze function up to 8 times within 40 minutes after the alarm first sounds. If you leave the ALARM switch ON, the alarm will sound again in 12 hours at the set time.

As mentioned above,  the 43003 Big Ben Twilight clock requires two AA (1.5V) batteries for power backup. These are not included, and we recommend alkaline batteries because they are far less prone to leakage than the carbon-zinc type. Also, their leakage is far less corrosive. It's a good idea to change the backup batteries once a year.

The Big Ben Twilight clock is intended for placement on a flat surface such as a nightstand, dresser, shelf, or the like. It cannot be wall-mounted.

With its easy setup and operation, the Big Ben 43003 Twilight is an alarm clock that almost anyone can use and appreciate. This clock is a perfect (and affordable) gift for almost anyone who likes the retro look of the mid-20th century. With authentic '50s styling, a modern quartz movement, and contemporary features like battery backup and snooze alarm, the Twilight is a quality clock that's also a time trip back to the early years of the Atomic Age.
