Which consequence arises if a chronometer's balance spring experiences significant temperature induced variations during celestial navigation?

💡 Explanation

When a chronometer's balance spring changes stiffness with temperature, isochronism deviates because temperature effects thermal expansion/contraction, leading to inaccurate timekeeping and errors accumulating over time. Therefore an increased great circle distance error results, rather than latitude/longitude estimation errors or compass accuracy affecting declination unless integrated into one complex navigational system.
