Atomix 00544 Montrose Atomic Aluminum and Glass 10-Inch Wall Clock
--by Chaney Instrument Co.

Featuring clean, modern styling and the latest technology, the Atomix 00544 Montrose atomic analog wall clock by Chaney Instrument is a great choice for rooms and areas in home, office, or school where a smaller or larger clock would, for whatever reason, be inappropriate. This is a quality atomic clock, with an aluminum surround and glass lens which will endure many cleanings without scratching.

The Atomix 00544 Montrose atomic wall clock features a brushed aluminum surround, a glass lens, and a white face with black hands and black Arabic numerals for both hours and minutes/seconds. At almost 10 inches in diameter, this clock is great for homes and offices with contemporary decor--and for small to medium-sized workspaces and schoolrooms.

Features:

Totally accurate--never needs resetting unless moved to a different time zone.
Sets automatically to WWVB radio signal.
Automatically adjusts for Daylight Saving Time unless DST bypass (disable) function is selected.
Manual time-set capability for use anywhere outside the WWVB signal range.
Brushed aluminum construction with a glass (not plastic) lens over a white dial with black hands and black Arabic numerals for both hours and minutes/seconds.
Powered by one AA (1.5V) alkaline battery (included), with expected battery life of up to 2 years.

Dimensions:

Diameter:
9.88 inches (250.8 mm)
Thickness:
2.0 inches (50.8 mm)

Atomix™ radio controlled clocks 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). Atomix analog clocks initially search for the WWVB signal once per hour. After synchronizing to the signal, they search 5 to 7 times per day.

The clock's quartz movement is a patented U.S. design. Its integral radio receiver detects the WWVB signal, and its microchip adjusts the hands to display the exact time. With only two controls--a pushbutton and a wheel that manually moves the clock's hands--setup is really easy. And the clock can optionally provide an audible indication of radio signal strength to help you find a location with good radio reception--a feature unique to the Atomix clock line.

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. You do this by holding the pushbutton depressed as you insert the battery and then releasing it after the battery is fully inserted. You then perform the normal setup steps as described in the instructions.

Also, if you want to set your clock, say, 5 minutes fast, you can do this manually after the clock synchronizes to the WWVB signal. Just set the time ahead by 5 minutes by using the wheel, and the clock will maintain the 5-minute difference indefinitely (or until you reset it).

If you move to a different continental U.S. time zone, you can adjust for it simply by using the wheel to adjust the time by the appropriate number of hours--the minute and second hands will automatically adjust themselves as necessary when the clock again receives the WWVB radio signal. Or, if you take the clock out of WWVB range, you can reset it for local time and it will continue to operate as a highly accurate quartz clock--but without the WWVB automatic time calibration. You do this by removing and reinserting the battery and using the wheel only--not the pushbutton--to set the time.

The clock is powered by a single AA (1.5 volt) alkaline battery, which is included and normally lasts up to 2 years.

Note: If you would prefer a larger or smaller wall clock and/or one of a different design and materials, please check out the numerous other Atomix wall clocks on this website.

Note: 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 the building can also effect 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 savings time change, the clock will not be able to set itself immediately if the signal is weak. Signal strength can be determined with an audible signal strength indicator. You may wish to enable the indicator when selecting a location for your clock. As wiring and plumbing in your walls can effect reception, moving the clock as little as a couple inches can make a difference in the strength of the signal reaching the clock. For additional information, please see the Chaney Instrument Clock FAQ.

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.
