Watches and Time

On wristwatches and digital displays

Wristwatches began to be used in a military context in the late 1800s, as the need for military movements to be synchronized was very important. Of course, there was a huge problem in accuracy with them, but they were good enough for the purpose.

They were generally wind-up powered. Automatic battery powered watches didn’t become possible until the 1920s. And digital displays weren’t common until the mid 1980s.
