When English actor Nicholas Hoult, star of the X-Men movie Dark Phoenix , walked the red carpet at the Venice Film Festival, the paparazzi went crazy, responding not only to the 29-year-old’s chiselled looks, but also to what he was flaunting on his wrist: a Jaeger-LeCoultre Polaris Date. Which of these 5 luxury watches is the thinnest in the world? The watch is equipped with two crowns and a rotating inner bezel to measure dive time. And despite its elegance, the Polaris is really a diver’s watch that can be used to a depth of 200 metres.
