Which navigational error becomes significant while using chronometers lacking temperature compensation?

💡 Explanation

A chronometer’s oscillation rate changes with temperature due to thermal expansion affecting the balance spring’s isochronism; this is thermoelastic instability. Longer voyages amplify timing errors, therefore longitudinal positions become increasingly wrong, rather than celestial or magnetic errors mattering.
