This dual time-keeping became necessary with the proliferation of railways. Trains started to conform schedules nationwide, and England had to adopt a standardized railway time, something that had never been attempted before.

In 1874 IWC was converted into a stock corporation. After two bankruptcies, IWC was taken over in 1880 by the Schaffhausen agricultural machinery manufacturer Johannes Rauschenbach. The new employee Urs Haenggi, who joined the company in 1883, proved to be an important support by making valuable contacts on business trips. Another employee, Johann Vogel, who was responsible for technical management, ensured that watch production ran smoothly, which was now increasing steadily. It was also he who introduced a new numbering system for the IWC calibers.

J. Rauschenbach’s heirs
After the death of Rauschenbach’s son in 1905, the IWC was bequeathed to Ernst Homberger-Rauschenbach and 25% to the psychoanalyst Carl Gustav Jung and his wife Emma Marie Rauschenbach-Jung and operated under the name of J. Rauschenbach’s heirs.
