Atomic clocks, rather than use gears or quartz movement as a timing standard, use electromagnetic waves as timing standards. Often the transition frequency used is in the microwave spectrum. This makes them extremely accurate since they use such very small units.
Yes, atomic watches can work anywhere in the world as they receive radio signals from atomic clocks to automatically adjust the time. This ensures precise timekeeping regardless of the location.
Atomic clocks typically run on electricity, which can be provided by batteries or direct connection to a power source. Some atomic clocks can also be powered by solar panels.
Pendulum clocks were largely replaced by more accurate clocks, such as quartz clocks and atomic clocks, in the late 20th century. Quartz clocks were first developed in the 1920s and became popular in the 1960s, offering better accuracy and durability than pendulum clocks. Atomic clocks, which are the most accurate timekeeping devices, have been in use since the mid-20th century for scientific and precision timing applications.
Instead of pendulums and gears or even quartz crystals, atomic clocks use the vibration between the nucleus and electrons of atoms -- usually cesium atoms -- to set the interval we use to measure time passing.
Cesium atoms are commonly used in making atomic clocks, as they are extremely consistent in their oscillation frequencies. By measuring the vibrations of cesium atoms, atomic clocks can maintain extremely accurate timekeeping, losing only about one second every 300 years.

Yes, there are many brands of atomic wall clocks.
Yes, atomic watches can work anywhere in the world as they receive radio signals from atomic clocks to automatically adjust the time. This ensures precise timekeeping regardless of the location.
Atomic clocks or rubidium clocks are commonly used in satellites for precise timekeeping. These clocks are highly accurate and stable, allowing satellites to track their position and perform various operations with precision.
Digital atomic clocks keep very accurate time and good tempature, in my experience.

Digital atomic clocks should only need a new battery every two or three years.

The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
Atomic clocks are in Federal Office of Metrology-Bern-Switzerland, National Physical Laboratory-Teddington-London-United Kingdom and at National Metrology Centre-Singapore. Atomic clocks are also in other countries as well.
All clocks can be compared for accuracy against the atomic clocks maintained by the US Naval observatory and National Bureau of Standards and (I beleive) the European Space Agency. Atomic clocks are almost more accurate than we can test them to be,
