What is the primary function of a watch?

Dorothy, A perfect example of the rule "form follows function".As people's lives became more governed by time, they needed a portable measuring device. First the pocket watch, then the wrist watch. Now the mobile phone. Just wondering what's next - brain implants?

LadyC313, The artificial _measurement_ of time is certainly man- made. However, the majority of living things must have somme rudimentary time sense, causing them to sleep, reproduce, migrate, hibernate, etc. at the appropriate time. Maybe keyed to daylight or temperature. Who decided on the human ways of dividing it up, is something for historians to debate. Usually by looking for the earliest references to it - which constantly moves things back.

Jamie, I use my phone to tell me the time

LadyC313, you already told us that 🙄

LadyC313, that was an easy one .

my brother has a smartwatch

isn't time a man- invented thing according to the position of the sun, stars and moon in te sky? still I don't know how they got to count it in, like earths rotation, in 360⁰ formation having hours minutes and seconds, even microseconds and nanoseconds? my brother answered '' because it's flat''. is his conspiracy theorism facts? lol commenting for my achievement, sorry.

Watches were preceded by clocks.
