Jn. Ls. Patron Quarter-Repeating Verge Pocket Watch

Partially verified

This late 18th-century Swiss verge pocket watch was produced by Jn. Ls. Patron in Geneva. The timepiece features a quarter-repeating mechanism activated via the pendant, which strikes a bell housed within the consular case. The exterior of the case displays a three-color gold finish, complemented by a central cartouche featuring a relief scene, with rope-pattern borders on the back and bezel. The white enamel dial is signed by the maker and presents Roman numerals for the hours and Arabic numerals for the minutes, paired with gilt hands. The key-wound movement is a full-plate construction with fusee and verge escapement, featuring a gold-plated finish. The balance cock is intricately pierced and engraved, fitted with a steel coqueret. The regulation is managed via a silver plate with a blued steel indicator. The auction description reports that the internal bell exhibits a crack.
