Worn by: Robert De Niro as Michael Vronsky
Reference: Rolex Sea-Dweller
Brand: Rolex
The Rolex Sea-Dweller 1665 is the perfect tool watch for Michael's character—an ultra-robust professional dive watch engineered to survive extreme depths and decompression. Just as the watch was designed with a helium escape valve to prevent catastrophic failure under pressure, Mike attempts to release his own psychological pressure through solitary deer hunting in the mountains. The watch's utilitarian design reflects Mike's working-class values and his philosophy of "one shot"—precision, preparation, and the professional's approach to survival. Unlike flashier Rolex models, the Sea-Dweller was built for those who actually use their watches in life-threatening conditions, mirroring Mike's transformation from steelworker to soldier to survivor.
