| The Patent for this unusual winding mechanism was taken out in 1873 by Haas. It is an ingenious solution for the provision of a winding mechanism that required little from the wearer other than normal use of the watch. Every time the cover is opened the barrel is wound approximately a quarter of a turn, the watch would need to be used about twenty times each day to keep it running. A rare watch:- few examples now appear for sale. See The Camerer Cuss Book of Antique Watches, Page 244. |
