A GPS watch is a device with an integrated GPS receiver that is worn as a single unit strapped onto a wrist, in the manner of a bracelet. The watch can have other features and capabilities depending on its intended purpose and be a smartwatch. GPS watches are most often used for sports and fitness purposes. Many can connect to external sensors by the wireless ANT+ protocol and/or to a computer by USB to transfer data and configuration. Common sensors used are heart rate monitors and footpods (running cadence and speed sensor). A footpod can be used to supplement or replace GPS data, such as providing treadmill speed and distance for the watch to log and share. Recharging by USB is commonplace.
