Like the "Olympic", "Titanic" was equipped with a large number of clocks supplied by the Magneta Company of Zurich (Switzerland), that were distributed throughout the transatlantic in passenger and crew spaces. These clocks, 48 in total, were controlled by two master clocks that were located in the chart room just behind the wheelhouse. Each master clock was capable of controlling 25 slave units in such a way that whenever the master clock advanced by one minute of time, the slave units that were connected to it would also advance by one minute of time, all in one synchronous operation.
