But here comes the trick. The second hand of an official Swiss railway station clock rotates the dial in 58 seconds in stead of 60. Exactly at 12 o’clock they take a rest. This rest enables the clocks on all Swiss railway stations simultaneously to be synchronized to the second, in fact to the minute, by a central master clock.
In that period of rest the minute hand moves to the next minute, and at exactly the first second of the next minute the second hands of all clocks simultaneously start to move again. So in fact during the course of the minute all clocks, as well as the Mondaine Stop2Go watch, are a little ahead. However when starting the next minute they’re all exactly on time again. Still with me?
