Gerard Butler wears a Casio G-Shock G7900 or similar watch in the movie Kandahar (2023).

The watch in the films seems to be a black and yellow Casio G-Shock G7900-3 but it has been modified by the product department, with the G-SHOCK and G logos looking mostly black. The Casio logo is not visible.

The Casio G-Shock G7900-3 is available at Amazon for $75 or you can find the red version (also $75).

Kandahar is a 2023 American action thriller film directed by Ric Roman Waugh and written by Mitchell LaFortune. The film stars Gerard Butler (who is also a producer on the film), and features a supporting cast that includes Navid Negahban, Ali Fazal, Bahador Foladi, Nina Toussaint-White, Vassilis Koukalani, Mark Arnold, Corey Johnson, and Travis Fimmel.

The same model Casio watch is worn by John Krasinski in 13 Hours: The Secret Soldiers of Benghazi (2016).
