In 2010, Miyota (Citizen Watch) of Japan introduced a newly developed movement (UHF 262 kHz) that uses a three-prong quartz crystal for the Precisionist or Accutron II line, a new type of quartz watch with ultra-high frequency (262.144 kHz) which is claimed to be accurate to +/− 10 seconds a year and has a smooth sweeping second hand rather than one that jumps each second. The Perpetual Chrono A-T synchronizes with the atomic clocks in Colorado or Germany, depending on signal strength and location, and incorporates Eco-Drive technology, so it does not require a battery. These features are comparable to the synchronization with atomic clocks found in Casio Wave Ceptor watches. The day, date, and daylight saving time settings are set automatically when the watch is synchronized. When traveling, the user may swap the 'home' and 'world' zones, thereby enabling proper time signal reception on a different continent while retaining the other time. The watch actually tracks two time zones-home and world-but synchronizes to the 'home' zone. ![]() The watches can synchronize with radio clocks in Japan, North America, and Europe, automatically selecting the correct frequency by location.
