George Clooney wears an Omega Speedmaster Professional in the movie The American. In the trailer we can clearly see a steel Omega Speedmaster Professional with black dial and black leather strap (modelnr. 3870.50.31). It might be the version with Transparent case back (modelnr. 3873.50.31) but we can't be sure until we would see the back of the watch.

Clooney is a brand ambassador for Omega, therefore he usually wears Omega watches. In another recent movie, Up In The Air, he wears an Omega DeVille.

The Omega Speedmaster is also known as the 'Moonwatch'. Read more about that in the article How the Omega Speedmaster became the Moonwatch.
