Watch Movements

The movement of a watch refers to the mechanics that power the ticking of the timepiece, and there are two main choices when it comes to analog watches (watches with hour hands and are not digital), quartz or automatic.
What you choose really comes down to what you're looking for in a watch. There are many ways to look at what's attractive about both types of watches, but one way to look at it is the quartz watch as more practical and the automatic watch as more emotional.

Quartz

The majority of watches made today utilize the vibrations of a tiny quartz crystal to maintain timing, with the power coming from a battery that needs to be replaced every 2 to 3 years. Watches with quartz movements are more accurate, losing about a minute of accuracy over a year, and they can have either analog or digital displays, or both.

Solar
Some quartz watches are solar-powered, storing light that enters through the dial face, which eliminates visits to the jeweler to change the battery.

Atomic
Atomic watches can be calibrated daily (or several times a day) via radio signals from an atomic clock (such as the one located in Fort Collins, Colorado). Atomic time is measured through vibrations of atoms in a metal isotope that resembles mercury. The result is an extremely accurate time that can be measured on instruments. Radio waves transmit this exact time throughout North America, enabling some atomic watches to correct themselves to the exact time.
