When they made the first clocks, how did they know whether they were accurate?

They had nothing to compare the clocks against, and I don’t think the stars and the sun would have made an useful target for comparison.

Kind of a side story. But I recommend you read Longitude by Dava Sobel. It covers the invention of a seaworthy watch to help sailors with their Longitude by ensuring the watch remains accurate.

Short book overall, but it definitely piqued my interest. Great read for sure.
