Bulova B1854 Altus Atomic Mantel Clock

The Bulova B1854 Altus Atomic Mantel Clock has a solid wood case with a mahogany finish. Bulova calls the styling contemporary, but it's definitely warmer than high-tech. The face is white with black markers. The hour and minute hands are black, and the second hand is gold-tone. The Altus mantel clock is medium in size at about 10 inches wide by 7.5 inches high, so you can use it not only above your fireplace but also on a table or shelf in your home or office.

The Bulova B1854 Altus Atomic Mantel Clock combines contemporary style and the latest atomic clock technology with the warmth of a mahogany-finished wood case. Under the clock's protective glass lens is an elegant white dial with black Roman numerals XII and VI at their respective positions and black graphic markers elsewhere.

Atomic (radio controlled) clocks like the B1854 Altus keep perfect time by calibrating themselves to 60kHz low-frequency AM radio signals containing time information supplied by the official U.S. atomic clock source in Boulder, Colorado. The radio signals are transmitted from radio station WWVB, which is located in nearby Fort Collins. Both the atomic clock source and WWVB are operated by the National Institute of Standards and Technology, or NIST (a part of the U.S. Commerce Department). The Altus clock initially searches for the WWVB signal upon insertion of the battery and, after synchronizing to the signal, searches several times per day thereafter.
The clock's quartz movement has an integral radio receiver that detects the WWVB signal, and a microchip adjusts the hands to display the exact time. With only a few buttons to press, setup is really easy. To access the movement (and its battery compartment), insert your thumb or finger in the hole in the wood cover on the back of the clock, lift the cover straight up, and swing the bottom of the cover out first. Then insert the included battery and press the time zone button for your location (PT, MT, CT, or ET). The second hand will advance 8 seconds in four 2-second increments and then search for the WWVB signal. If the signal cannot be received, the hands will advance to 4, 8, or 12 o'clock and search each hour until the signal is received. Don't forget to replace the back cover.
This clock displays the precise time in any location where the WWVB radio signal can be received. This includes the continental U.S. (the "lower 48") plus parts of Canada and Mexico. Daylight Saving Time adjustment takes place automatically in the spring and fall, but if you live in Indiana or Arizona, you can disable DST by pressing the DST-deactivate pushbutton for 1 second. To reactivate the DST change, press the button again for 1 second.
If you move to a different continental U.S. time zone, you can adjust for it simply by pressing the correct time zone button. Or, if you take the clock out of WWVB range or use it in a location where the time signal cannot be received, you can use the manual time set button to set the clock for local time, in which case it will continue to operate as a highly accurate quartz clock--but without the WWVB automatic time calibration.
The Altus atomic clock is powered by a single AA (1.5 volt) battery, which is included and normally lasts about 1 year. When the battery gets low, the clock tells you this by advancing its second hand in 2-second increments. We recommend using an alkaline battery when replacement becomes necessary.
Note 1: Included with this clock's instructions is a brass-tone metal engraving plate with an adhesive backing. If the clock is a special gift, you can have the plate engraved with a name and notation of your choice. The plate fits in the recessed vertical area on the front of the clock base in the center.
Note 2: The 60kHz AM radio signal used by NIST to deliver the time information carries best at night. The signal may be interfered with by weather conditions and local interference. Building construction and location within a building can also affect reception. This clock is quartz controlled and will keep very good time for days when reception is poor, so this isn't normally a problem. You may find, however, that when you first insert the batteries, or during a Daylight Saving Time change, the clock will not be able to set itself immediately if the signal is weak. As wiring and plumbing in your walls can affect reception, moving the clock as little as a couple of inches can make a difference in the strength of the signal reaching the clock. You can test a potential clock location by tuning a portable AM radio to a weak station (preferably one in the direction of Colorado) and placing it in the proposed location. If the signal fades significantly, the location is probably a poor one for an atomic clock.

Note: This product has "atomic" clock functionality. Atomic, or Radio Controlled clocks receive a radio signal to set themselves. 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 other electrical equipment that may generate interference, or if the weather is unsuitable. 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. That's normal. By morning, weather permitting, it should be correct. Under less than ideal conditions, it could take a few days. Daylight savings time changes may not be made the first night if location and weather are not favorable.
