Romain Jerome's post-apocalypse-punk Night and Day watch can just barely be described as a time piece: it only reports day or night.
World First – An exceptional timepiece that does not indicate the time!
With no display for the hours, minutes or seconds the Day&Night offers a new way of measuring time, splitting the universe of time into two fundamentally opposing sections: day versus night.
A new interpretation of Time based around two Tourbillons operating sequentially. The Day Tourbillon operates during the day, defining the wearer’s period of activity, and stops after twelve hours, handing over to the Night Tourbillon dedicated to man’s own private sphere.
Perfect for vampires or wasteland scavengers trying to descry bedtime through the heavy radioactive smog.
