I have started another sticky thread to collect references to known specialists in the repair and service of marine chronometer and other precision timekeepers. I listed the ones I know about to start us off. Please PM me with further chronometer service persons for the list if you know of them. Disclaimer: The NAWCC has no commercial affiliation with any of these parts sources or service persons, and the listings herein do not represent any recommendation or warranty. This list is made available as a public service to assist our users to obtain uncommon and highly specialized chronometer parts and services. All transactions must be conducted privately and are at your own risk. Should any problems be encountered please report them to the forum Moderator.
