Atomix
75315 Hartwell Atomic
10-Inch Analog Wall Clock, in Silver
|
|
| The Atomix 75315 Hartwell
Atomic Analog Wall Clock by Chaney Instrument Co. has a molded case
that's metallic silver in color. We'd describe this shade of silver as
medium because it's a little darker than the light silver color that
seems to be more common on time and weather products. The clock has a
plastic protective lens and a white face with black hour, minute, and
second hands. The black Arabic numerals are large (about 3/4 inch) and bold for easy
reading from a distance. At 10 inches in diameter, this is a plain,
no-nonsense, inexpensive clock that's perfect for small to medium-size
rooms and workspaces in homes, offices, schools and businesses.

This Atomix
Hartwell wall clock features a metallic silver plastic case, a
plastic protective lens, and a white face with black hour,
minute, and second hands. The large and bold Arabic numerals are
easily read, even from a distance. At 10 inches in diameter,
this plain, no-nonsense clock will look great in small to
medium-size rooms and workspaces in homes, offices schools, and
businesses. |

Atomix radio controlled ("atomic")
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.
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 Hartwell clock is
powered by a single AA (1.5 volt) alkaline battery, which normally lasts
up to 2 years. The battery is not included and must be obtained
separately.
Featuring simple, functional
styling and the latest technology, the Atomix Hartwell clock is designed
for easy reading in small to medium-size rooms and workspaces where a
larger clock would look out of place.
Note 1: This
Hartwell clock is also available in black and in white. Or, if you would
prefer a wall clock of a different size and/or of a different design and
materials, please check out the numerous other Atomix wall clocks on
this website.
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 the 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 reception is poor. Signal strength
is indicated by the icon above seconds in the time display. You may wish
to check the icon when selecting a location for your clock. Because
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. 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.
