According to the repair books, this chronometer was returned for overhaul on 20 December 1824 at the request of Monsieur Texier. The punch mark for Joly has been removed from the interior of the back of the case, almost certainly at the same time as the owner’s name or coat-of-arms were removed from the exterior, probably at the request of the family. The number 4084 has been re-stamped.
