Time is of the essence, and no one knows that better than Swiss watchmaker Jaeger-LeCoultre, which is why it has teamed up with industrial designer Marc Newson to re-envision its famous Atmos clock, which runs on thin air. Only 888 of the Atmos 561s ($20,500) will be produced in honor of both the clock's 80th birthday and the 175th anniversary of the company.
