Which adjustment was essential for marine chronometers to maintain accurate time within long voyages across the fluctuating temperatures?

💡 Explanation

When temperature changes occurred, thermal expansion affected the balance spring’s oscillation rate, causing clock drift therefore temperature compensation used bimetallic strips, which flexed with temperature changes to adjust the balance wheel’s effective inertia. Therefore temperature compensation was essential rather than winding, shielding, or sealing which mitigated other issues.
