IWC Ceralume Concept Watch
If you’re wondering what on Earth that watch Lewis Hamilton had at the Monaco Grand Prix was, it’s actually a proof of concept. It’s a one-of-a-kind Pilot’s Watch Chronograph 41 that IWC made to showcase Ceralume, its luminous ceramic material. Amazingly, IWC claims that Ceralume watch cases can glow in the dark for more than 24 hours.
