This Day & Night watch is for the rich and not time conscious as this is the $300,000 watch that doesn’t tell time - only whether it’s day or night.

As the company’s Web site boasts: “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.”

What’s most impressive about the Day&Night is its complexity, given its absolute uselessness. The watch features two tourbillons — devices that overcome the ill effects of earth’s gravity on a watch’s accuracy — connected by a differential mechanism. Instead of hands, the watch has a “contemplative tourbillon operation whereby the ‘Day’ tourbillon operates for 12 hours to symbolize working life, while the ‘Night’ tourbillon takes over afterward to represent an individual’s private time.”
