Many thanks to Jay and Gary who provided more images the watch

Sadly, this is the closest picture I could get of the gold Bvlgari watch that is worn in Tony Stark's garage/workshop. The movie watch shares the gold case and "Bvlgari Bvlgari" names on the bezel, though it has a new chronograph feature which utilizes two retrograde indicators on the each side of the face. Traditional Bvlgari chronograph watches features typical round subdials for the chronograph registers. Use of retrograde registers is a stylistic approach that offers a more unique sense of functionality. Assuming I find images of the exact watch, I will place them in this post. Any heads up would be appreciated.

In accordance with the first watch worn in the movie (the Hublot Big Bang), Robert Downey Jr. was seen wearing an Orange numbered Bell & Ross BR 01-94 in an interview about the movie. This indicates that Mr. Downey Jr. is indeed a watch fan owning several tech luxury watches. These are perhaps not the most challenging of watches to acquire, but at least he is interested in owning them. Good for him.

Also of immense popularity among the Hollywood crowd are Panerai watches (mainly due to Sylvester Stallone), and IWC. Of course Omega and Rolex have their deeply ingrained popularity as well. But what I really like to see is when a star wears something totally out of the ordinary (I'm not talking about a Timex). I mean a nice and rare watch that signals the wearer put effort in to acquiring or learning about. Not merely something they walked into Westime (popular luxury watch store in Los Angeles) and picked out. Look out for more movie watch sightings.
