RARE ANTIQUE STERLING SILVER Key Wind POCKET WATCH by R. JOHNSTONE, LONDON 1812. The only other one I could find is in the CATALOGUE of the NATIONAL MUSEUM of ANTIQUITIES of SCOTLAND (page 367). It seems to run but has not been tested, face is cracked, otherwise in good condition for a watch well over TWO CENTURIES OLD, please see all pictures. Measures approximately 2 1/4 inches across. Shipping includes insurance. A VERY RARE WATCH WITH NO RESERVE!
