Description This excellent Acctim watch looks the part and also delivers on the functionality front, too. The most precise time keeping device on earth is the atomic clock. It keeps time to the accuracy of better than 1 second for every 60 million years. The atomic clock is a huge piece of scientific equipment and it is so expensive that it is normally found in laboratories and standards institutions etc. Thanks to the latest technology, the accuracy of the atomic clock is now brought to your home. The radio station is broadcasting electronically encoded time signals based on an atomic clock from an antenna in Anthorn of UK (MSF version) to cover the mainland of the country. The signal is picked up by the radio receiver circuit in your watch, and is then decoded to synchronize the time to within a split of a second precision. The radio signal automatically sets the calendar and daylight saving (DST ) or standard time (STD ) too. The watch is a radio device and like the mobile phone or the radio, in certain locations and at certain time of the day, it may not be able to pick up signal strong enough to synchronize. If the watch fails to synchronize in the first attempt, it will re-attempt every 2 hours for the first 3 days. In most cases, the watch synchronizes overnight as the radio signal is the strongest and cleanest in the early morning. You may leave the watch to synchronize to the right time later or you may temporarily set the watch manually.
