Ca. Ø42mm, ca. 77g, 18K pink gold, exceptional quality Louis XV case, finest sound openings, back with an exceptionally beautiful enamel painting, altar of love on the shore of Lake Geneva, sailing boats in the background, sky engine turned enamelled, evening atmosphere with sunset, painting framed by small white enamel beads (partially rubbed), bell, signed and numbered verge movement, No.1037, repeating the hours and quarters, either on the bell or on the rim of the case with knob for the 'silent or secret' repeater without sound, original enamel dial, signed, magnificent hands set with stones, movement and striking mechanism intact, but repeater needs adjustment. The watch is of fantastic quality and in our opinion completely original. Only the dial has been minimally and professionally restored at the winding hole. The Bonna Freres company in Geneva made the finest enamel watches. Around 1780 they became partners with Mourier and signed the watches 'Freres Bonna & Mourier'. This watch was therefore made before 1780.
