Robert Duvall wears an unidentified watch

Tom Hagen is the only person in the Corleone family who chose to be there. Robert Duvall plays him as Vito's adopted son and consigliere, a man who went to law school and came back to serve as the legal and strategic brain of a criminal empire. He is Irish and German in a Sicilian family, which means he can never be Don, and the film makes clear that he knows it. Hagen negotiates, advises, and occasionally delivers threats with the calm professionalism of someone filing a legal brief. When Sonny is murdered, Hagen is the one who tells the Don. When Michael orders the baptism massacres, Hagen is the one who organized the logistics.

Duvall wears what the Exquisite Timepieces blog describes as "a reserved but rich gold dress watch," though the make and model cannot be determined from the footage. For Hagen, a gold dress watch makes sense. He is the family's public face: the man who walks into Hollywood studios and judges' chambers and government offices on behalf of the Corleones. His watch, like his suits, would be conservative enough to pass in legitimate circles and expensive enough to signal that the family he represents has resources. Hagen does not flash. He presents.
