Jumping seconds mechanism or "seconde morte" Lange felt that the readability of the jumping auxiliary seconds was not satisfactory in a pocket watch, so he started following another course. By 1867 he had designed a mechanism which allowed an independent large central seconds hand to jump every second. The hand had a stop device but could not be reset to zero. 1877 his sons filed a patent for a slightly modified version of A. Lange's mechanism (no. 182). This seconds mechanism on a 3/4 plate created a precision watch which had the indication system of an astronomical pendulum clock but was portable. Source: Reinhard Meis "A.
