When sailing, using a marine chronometer, which consequence occurred if its balance spring suddenly cold-welded?

💡 Explanation

With a cold-welded balance spring, the chronometer stops, ceasing precise timekeeping via *isochronism*. Therefore, calculating longitude becomes impossible using time differences, rather than impacting the compass that relies upon magnetism.
