Benjamin Haas English patent No. 3945 of December 2, 1873 was granted to Benjamin Haas for the development of a novel and unusual winding mechanism, which used the energy that is generated when the front cover of the watch is closed. Haas improved the original idea further andhis watch possesses a well-developed system with a 36-hour power reserve (generated by twelve closings). Haas changed the going train by adding an additional wheel so that a single closing was able to achieve three hours' winding. He also invented a safety device which disengaged the mechanism when fully wound and thus prevented any damage to the cover. Cond.: Case: very good, slightly worn. Dial: very good. Movm.: very good, capable of running, cleaning recommended. "
