A 6538 “Big Crown,” the model Connery wore in Dr. No, From Russia with Love, Goldfinger, Thunderball. Highly collectible. Maybe even a gilt dial version.
Addendum: Oh, just read “original bezel, dial, hands.” Very rare indeed AFAIK. Many were replaced during service jobs.
Google is your friend. Read a bit. I’m sure there’ve even been threads here on the forum about it.
