The Cushion B watch dates back to the early 1930s, the Endicott toward the end of that decade, while the Lexington seems to have been made prior to the attack on Pearl Harbor, with a rather short production run into the early 1940s. While it’s hard to take it all in on the first viewing of a film, it appears as though the Cushion B and Endicott watches are most visible in Oppenheimer. If you see otherwise, please let me know. I’ll be catching a second viewing in 70mm soon anyway, to be sure.
