Howard & Co. 2012, EHWC, Inc. begins development to manufacture high-end wrist watches in Boston. 2013 A new world record was set on Saturday, November 23 at Fontaine’s Auction Gallery in Pittsfield Ma. when an E. Howard No. 68 Astronomical Regulator clock was sold for $277,300.00 ...
La Crosse Technology introduced the radio-controlled clock, commonly (but incorrectly) called an "atomic clock" after the extremely accurate timepiece behind the radio signal it uses as a reference, into the United States commercial market in 1991. [3] [4] In 2004, the company was awarded a license to sell The Weather Channel branded weather ...
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
WWVB's Colorado location makes the signal weakest on the U.S. east coast, where urban density also produces considerable interference. In 2009, NIST raised the possibility of adding a second time code transmitter, on the east coast, to improve signal reception there and provide a certain amount of robustness to the overall system should weather or other causes render one transmitter site ...
After a reset, battery change or power failure, these clocks without a backup battery or capacitor either start counting from 12:00, or stay at 12:00, often with blinking digits indicating that the time needs to be set. Some newer clocks will reset themselves based on radio or Internet time servers that are tuned to national atomic clocks ...

Atomic clocks are installed at sites of time signal radio transmitters. [103] They are used at some long-wave and medium-wave broadcasting stations to deliver a very precise carrier frequency. [104] Atomic clocks are used in many scientific disciplines, such as for long-baseline interferometry in radio astronomy. [105]
