These watches are heavily influenced by classical Swiss railway clocks, called the Official Swiss Railways Watch / SBB, with the design licensed from the Swiss Federal Railways in 1986. This design, by Hans Hilfiker, originated in 1944.

In 1944 the Swiss Federal Railways (SBB) tried to improve the punctuality of their train services by synchronizing the clocks on all railway stations to one master clock, this was achieved by sending time signals via the telephone system to each clock, in 1953 the second had was added, this was synchronized by running a little fast, by about 1.5 seconds every minute then stop at the 12 o'clock position and wait for the time signal before advancing the minute hand and resuming.
