Winnerl, No. 433, circa 1845.Very fine and rare 18K gold, 32 hour going, early keyless pocket chronometer with power reserve indicator, in original fitted box. Notes Due to the difficulty in producing a stem winding system for a movement with fusee and chain, very few keyless pocket chronometers of this type were produced. This is certainly one of the earliest ever made.
