The WS6002U-A digital atomic wall clock displays not only the time, day, and date but also the indoor temperature. Featuring contemporary styling, the clock has a raised black display panel and a brushed aluminum background panel. The background panel is a little darker in color than some brushed aluminum we've seen, and it looks great behind the black display panel.

The LCD display panel that stands out 1/2 inch from the contrasting aluminum background panel gives the WS6003U-A true 3-dimensional appeal. A curved top and bottom add to this clock's visual interest.

The WS6002U-A is medium in size (about 8.3 x 8.4 inches) and has large digital displays for great readability. Hour and minutes are indicated in extra-bold digits more than 2 inches tall. The LCD display below the time is about 1 inch tall and has 3 user-selectable display modes:

  • Month and date / weekday / indoor temperature.

  • Month and date / weekday / clock seconds.

  • Month and date / clock seconds / indoor temperature.

Mount this clock on a wall, or extend the clock's integral foldout stand to use it as a freestanding unit on a table or shelf.

Note: Would you prefer this same clock with straight (horizontal) top and bottom? Please check out the WS6003U-A on this website.


Features:

  • Atomic clock sets automatically to WWVB radio signal (manual setting is also possible).
  • User-selectable12- or 24-hour time display. Please be aware that, because of the width of the LCD panel, the first digit 2 cannot be displayed in 24-hour mode.
  • Calendar display with weekday abbreviations in your choice of three languages (English, French, Spanish).
  • Three display modes for month and date, weekday, clock seconds, and/or indoor temperature. Month and date are always indicated, and you can select any two of the other three parameters for display.
  • Time zone setting (13 available).
  • 3-letter identification for U.S. time zone.
  • Daylight saving time ON/OFF option.
  • Indoor temperature display in either F or C.
  • Powered by two AA alkaline batteries (not included), with normal life of about 1 year.

Specifications:

  • Indoor temperature measuring range:
    32 to 122F with 0.2F resolution
    (0 to 50C with 0.1C resolution)
  • Temperature checking interval:
    Every 10 seconds
  • Dimensions:
    8.30 inches (211 mm) wide
    8.42 inches (214 mm) high
    0.98 inch (25 mm) deep (excluding foldout stand for shelf or table placement)

Radio-controlled Time:

The NIST (National Institute of Standards and Technology, Time and Frequency Division) maintains a radio station, WWVB, in Ft. Collins, Colorado. The WWVB radio station derives its signal from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists is continually measuring every second of every day, to an accuracy of ten billionths of a second per day. These physicists have created an international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133 atom in a vacuum.

WWVB (the stations identification just like any other radio station) continuously broadcasts time and frequency signals at 60 kHz. The carrier frequency provides a stable frequency reference traceable to the national standard. There are no voice announcements on the station, but a time code is synchronized with the 60 kHz carrier and is broadcast continuously at a rate of 1 bit per second using pulse width modulation. The time code contains the year, day of year, hour, minute, second, and flags that indicate the status of Daylight Saving Time, leap years, and leap seconds.

The La Crosse Technology WS6002U-A Digital Atomic Clock:

The La Crosse Technology Digital Atomic Clock maintains its incredible accuracy by automatically tuning into the WWVB radio signal. The built-in antenna ensures reliable signal reception up to 2000 miles (3200km) from the WWVB transmitter. As a result, the La Crosse Technology clock will calibrate to the atomic clock not only throughout the mainland U.S. but also in much of Canada. You need only insert the batteries, wait until the signal is received, and program the desired additional settings. In locations outside of WWVB range, the La Crosse clock can be manually set and will provide the high degree of accuracy of any quality quartz clock.

In a nutshell, here's how the the La Crosse clock works: The clock's antenna is specifically tuned for optimal reception of the 60 kHz time signal. The time signal received on the antenna is demodulated by an onboard receiver, which sends the information to the clock's CMOS microprocessor for decoding. Once your clock has automatically set its time for the first time, it ensures continuing accuracy by automatically tuning into the WWVB radio signal once per day at midnight. (If no signal is detected, the clock performs its WWVB check hourly until the signal is found.) As long as your clock is kept within transmitter range, it will continue to display the absolutely precise time, automatically adjusting for summer time/winter time changeovers if the daylight savings time option is ON. Should you move your clock out of transmitter range for an extended period of time, the clock will continue to operate as a highly accurate quartz-controlled clock. Upon re-entering the transmitter range, your clock will correct itself again to the precise WWVB time signal.


Note: This unit has atomic clock functionality.  The clock can receive time broadcasts from the U.S. Atomic clock transmitter in Colorado, and synchronize itself to the U.S. Atomic clock every night.  As long as the signal is strong where the clock is located, the clock will maintain accuracy to a fraction of a second, and reset itself for daylight savings time (unless you choose to disable the DST function).  However, if the clock is located where the signal is poor, due to metal in the construction of your building blocking the signal, or due to electrical interference from nearby electrical appliances or computers, then the clock may not always receive adequate signal.  Under these conditions, the clock may still synchronize occasionally, when weather conditions are ideal, or may need to be set manually.
