This reminded me of the book "Longitude", a tale of truly epic clock-making: https://en.wikipedia.org/wiki/Longitude_(book) https://en.wikipedia.org/wiki/Longit

  It’s a good book. The story is more nuanced than people often realize. Most definitely Harrison was treated poorly, however, while he created chronometers that met the latter of the challenge, he didn’t really help with this spirit of the problem. A true solution needed a mass produced chronometer. It’s also often misrepresented that he was the person who solved the “how do you measure your longitude“ problem. It was well understood that you needed to be able to accurately measure the difference between local time and time at a known meridian. The questions where about how to accurately and practically measure that.
