Carl F. Bucherer's Patravi TravelTec FourX

With a pretty insane three timezones (!), Carl F. Bucherer's Patravi TravelTec FourX is made from four materials - palladium, titanium, ceramics and rubber. It must rank as one of the most complex watches ever made.

And at a near 47mm is among he largest as well.

But I find myself thinking "I can't actually tell the time with this!"
