Brad Pitt wears an IWC Ingenieur SL 1832 watch with a custom green dial in the 2025 movie F1.

According to an article at Monochrome watches, this is a 1976-inspired Ingenieur SL 1832 with a bespoke green dial.

The watch has a round case, a green dial, very simple straight hands and hour markers. The polished bezel has 5 screws/holes, which are off center in the images.

The most similar watch you can get is a new release from IWC that celebrates the appearance of the watch in the film. A collaboration between IWC, Pitt and Cloister Watch Company, the prop watch is now available as the IWC Ingenieur Automatic 40 Green but it's not a 100% the same as the vintage movie watch.

F1 is an American sports action drama film directed by Joseph Kosinski featuring the Formula One World Championship starring Brad Pitt, Damson Idris, Kerry Condon, Tobias Menzies, Kim Bodnia, and Javier Bardem.
