Last week’s Iron Man 2 premiere was switched from London to Los Angeles at the last minute, because apparently not even Tony Starks’ armour suit was a match for the cloud of volcanic ash that had recently closed Britain’s skies.

Examining the red carpet shots of the cast, anyone who can tear their eyes away from Gwyneth Paltrow and Scarlett Johansson might notice that Robert Downey Jr. took the opportunity to underscore his affection for Jaeger-LeCoultre watches by wearing an Amvox3 Tourbillon GMT.

There’s a huge amount to say about this beautiful watch but the highlights, aside from the 988 movement, include the jumping date indicator and the fact that this is the first time any watchmaker has made a ceramic case in-house.
