I've seen several people here post when they see a movie with a girl wearing a watch. Those posts are the reasons I've seen several movies (and I'm glad I did!!). A few times when I was trying to pick a movie to see I came here but couldn't find very many suggestions.
Let's make this thread a list of movies. It'd be best if the girl wore the watch for the majority of the movie, not just a brief scene. Include the movie title, actress, type of watch, and whether or not you liked the movie

I'll start:
-Picture Perfect. Jennifer Aniston wears a medium sized woman's Rolex, and for a very brief scene she puts on a kid's watch right next to her Rolex. Decent movie!
-Morning Glory. Rachel McAdams wears a small leather strapped watch. Also a decent movie. I was entertained the whole time, especially by Rachel McAdams!

-Land of the Lost (new one). Anna Friel wears a large digital faced watch. Doesn't take it off.

-Knight and Day (as posted by someone else here!). Cameron Diaz wears that awesome sub for the first 2/3rds of the movie. I liked this movie...
-Life As We Know It (also previously mentioned on here!). Katherine Heigl wears a medium sized gold watch... Decent movie.
-Good Luck Chuck. Jessica Alba wears a men's Rolex for most of the movie (I think...), and I enjoyed this movie!
There are SO many more... Let's get this going so that next time we go to pick a movie, we have a list to choose from
