When shopping for a watch, learning the terminology will help you to communicate exactly what you are looking for.
Quartz : The movement of a watch powered by a battery-device and the oscillations of a quartz crystal. This is one of the more accurate timekeeping methods available.
Water Resistant: This is a big one, because this label does not automatically mean you can submerge your watch. Water-resistant has a wide range of abilities and only those that say water resistant to 100 meters can be submerged.
Movement : This refers to the movements of the bits and pieces of a watch, inside and out.
Complication : This term refers to any component of a watch that does not have to do with timekeeping. For example, extras like calendars or alarms fall into this category.
