This Marine Chronometer was brought in for repair as it had been badly damaged during shipment from overseas. 



The escape wheel pivots, balance wheel pivots, detent and lower balance jewel were all broken. The impulse jewel was chipped, and the unlocking jewel was missing and had been replaced with a steel substitute. New jewels were fitted to new rollers, the lower balance jewel was replaced, screws were polished and parts were either repaired or replaced.



The whole piece was completely restored, and the escapement was set up and adjusted for optimal performance.

Please view the photos taken during restoration.
