Which limitation constrained accurate celestial navigation pre-1750 due to clock mechanisms?

💡 Explanation

The longitude problem required highly accurate timekeeping; however pendulum clocks experienced unreliable isochronism, which involves swing period changing with amplitude, because subtle differences in mounting and environmental differences altered pendulum's period. Isochronism, therefore, caused drift, rather than purely mechanical failures.
