Which navigational error increases after repeated mechanical chronometer shocks during rough ocean voyages?

💡 Explanation

When a chronometer experiences repeated shocks, isochronism errors accumulate because each perturbation subtly alters the balance wheel's oscillation period, disrupting precise timekeeping used for longitude calculations. Therefore longitude error increases additively, rather than latitude being affected, great circle paths being incorrect due to shock events or compass fluctuation, which require different disturbances.
