BRG HP15A DuraTime HP 15-Inch Diameter Analog Wall Clock with Brushed Aluminum Bezel

The DuraTime HP15A clock is a 15" diameter high precision 110 VAC wall clock with a brushed aluminum bezel. Once configured, this clock won't need to be adjusted again for 20 years, except to add the occasional leap second. All DuraTime HP clocks are factory-synchronized with the U.S. atomic clock and set to your local time zone and DST requirements with the included software.

Yes, thanks to the oven-controlled crystal oscillator (OCXO) that is accurate to 2 ppb, you can set it and forget it (except for those pesky leap seconds) for two decades.

Here are few more key points about all DuraTime HP clocks:

• No batteries are required, but a plug is: all DuraTime HP clocks operate on 110 VAC
• Automatically adjusts for DST
• No master clock is required
• These clocks can be deep inside a building, underground, or behind thick walls: they do not use radio, GPS or CDMA signals to keep time
