Worn by: Adam Driver as Charlie Barber
Reference: Rolex Oyster Perpetual
Brand: Rolex
Brooklyn-based playwright Charlie Barber wears a Rolex Oyster Perpetual 39mm ref. 114300 with a sunray blue dial and lime green accents throughout the film as he navigates an increasingly hostile divorce and custody battle. Released in 2015, this watch effectively reintroduced the OP line with colorful dials, featuring partially lumed dial markers at three, six, and nine, and lacquer-like finish to the painted numerals in green. The watch has since been discontinued and replaced by the OP 41 line. This appears to be Adam Driver's personal watch, as he's been spotted wearing it in interviews promoting other films. The Rolex is visible in almost every Driver scene, prominently displayed during the opening montage and during a tense phone call with Nicole's lawyer in a theater stairwell.
