PP, I'm afraid I'm no good on watches. Cars, yes. Watches, no.
The Havana sequence is so authentic that history professors urge their students to watch GFII so they can get a feel for what Havana looked like just before Castro took over. Among the authentic touches are the uniforms of the bellmen at the Capri hotel when Fredo shows up, the design of Michael's and Roth's hotel rooms, and the New Year's Eve show featuring Yolanda. You may also have noticed that, at the end of the scene, Cubans are bashing parking meters. That really happened: revenue from the meters was supposed to go to a children's hospital, but it ended up in Batista's pockets.
