E C Bracebridge & Company, 8 Red Lion St, Clerkenwell, "Watch Manufacturers, established 1780." Important London watchmakers and producers of good and often interesting watches, mostly bearing retailers names, with many sold into the north and south American market. They are little known today but fully deserve to be properly researched - they were succeeded by Wright & Craighead.
Patent No 2330, September 1865 "Improvements in watches, and in the method of and apparatus for winding up fusee watches..." David Keys & Son 'Chronometer & Watch Manufacturers' 15 Craven St, Strand, later with a retail shop in Piccadilly, an important but now little know London firm who supplied many fine and interesting watches to numerous retailers.
This fine watch has been worn, which is not at all surprising, and there are the usual minor signs of use. The lovely dial has also been very well restored at some point, but there are no serious faults and I am selling it for its previous owner who had it serviced some years ago. It is running well, but I can have it freshly serviced if required.
