The Cushion B watch dates again to the early Thirties, the Endicott towards the tip of that decade, whereas the Lexington appears to have been made previous to the assault on Pearl Harbor, with a relatively quick manufacturing run into the early Forties. Whereas it is exhausting to take all of it in on the primary viewing of a movie, it seems as if the Cushion B and Endicott watches are most seen in Oppenheimer. In the event you see in any other case, please let me know. I will be catching a second viewing in 70mm quickly anyway, to make certain.
