In the early 1870’s Richard Lange (1845-1932) started designing a new chronograph which had the mechanism above the train, so that the mechanism could be attached to a “normal” watch movement. The upper seconds bearing received a new bridge and acted as the bearing for the clutch lever. A central chrono wheel with an upper steel bridge was fed through the minute wheel and all levers and springs were highly ground and bevelled. The mechanism was operated by a pusher in the crown, with the sequence being start, stop and reset. The most basic version only had one chronograph hand, chronographs with minute counters were much more complicated.
