Time in space is precious, and several time-keeping devices help the astronauts stay on their schedule of tasks. One of the most popular timepieces in the Space Shuttle era was the durable Casio G-Shock (gravitational shock) wristwatch with stopwatch feature and countdown timer. It is resistant to vibration, water, and being struck. Often worn by athletes and military personnel, it holds up to rugged wear and tear. NASA sent this watch to the Museum after it was no longer needed for astronaut use.
