Worn by: Cary Grant as Brian Cruikshank
Reference: Rolex Oyster Royal
Brand: Rolex
Regina "Reggie" Lampert plans to divorce her secretive husband Charles but returns to Paris from a skiing holiday to find their apartment emptied and Charles murdered. At his funeral, three menacing men verify he's dead. CIA administrator Hamilton Bartholomew reveals Charles and the three men—Tex Panthollow, Herman Scobie, and Leopold Gideon—stole $250,000 in gold during WWII while on an OSS mission. Charles double-crossed them and the money remains missing. Peter Joshua, a charming stranger Reggie met on vacation, reappears offering help, but his identity keeps changing—first claiming to be Carson Dyle's vengeful brother Alexander, then thief Adam Canfield. As the criminals threaten Reggie, they're murdered one by one. Bartholomew claims Dyle had no brother, deepening the mystery. Reggie discovers Charles converted the gold into rare postage stamps. Believing Peter killed everyone, she attempts to deliver the stamps to Bartholomew but discovers he's actually Carson Dyle, who survived the war ambush and seeks revenge. Peter saves Reggie as Dyle falls through a theater trapdoor to his death. Peter reveals he's actually Brian Cruikshank, a U.S. Treasury agent recovering stolen property. He proposes marriage, and Reggie jokes about naming their children after all his aliases. The waterproof Rolex Oyster Royal becomes plot-relevant when Peter takes a fully-clothed shower, pointing to his watch and saying "waterproof."
