Few dials are as recognisable as that of the Official Swiss Railways clock, which Mondaine has successfully produced in a wrist-friendly format for more than three decades. But with such a classic design comes the challenge of how to update it for modern day needs without losing the essence and charm of the original.

And that is just what the watchmaker has achieved with Mondaine Backlight Technology, which uniquely ensures you can always see the time in the dark. Luminous paint has been applied underneath the hands, revealing itself when illuminated at night. Throughout the day, light reflects off the white dial to constantly charge the material so you can clearly see the hour after dark.
