Romain Jerome a company that makes luxury watches has came up with a concept watch that measures sunlight. An exceptional timepiece but no hour or seconds here just night and day.

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.

The Day and Night watch is a extremely limited edition and only 9 pieces were made which instantly sold out although each piece was going for $300,000.
