High visibility wireless clock

These bright LED-digital wireless clocks are ideal for large areas of a building such as long hallways, large manufacturing areas, etc. - because they're viewable over 100 feet away. The display LEDs illuminate behind an attractive red Plexiglas contained in an all metal housing and with bright, clear and easy-to-read numbers, they're hard to miss.


Choose the AirTime Wireless system to fit your business

AirTime wireless clocks don't need manual setting, they keep time during power failures and automatically adjust for Daylight Saving Time. AirTime wireless clocks receive the wireless time signal from either the Lathem ATX or Lathem ATX6 Transceiver and display the exact time to the millisecond. Choose between WWVB radio signal (Atomic clock), Ethernet or GPS AirTime transceiver signal options as your synchronized and precise time source.
