Which navigational error became critical upon relying entirely on timekeeping alone?

💡 Explanation

When relying exclusively on chronometers for longitude during long voyages, accumulated time errors multiplied by Earth's rotation, leading to growing longitude errors with distance. Therefore longitude errors become significant, while range, heave and easting were addressed through other methods or local observations.
