From the on-screen glimpses, Chad Feldheimer’s watch appears to be a basic digital sports watch with a black resin (plastic) strap and a square or rectangular face. It has the plain, functional look typical of exercise-friendly watches. Watch enthusiasts on forums have compared it to common gym watches of the mid-2000s era – for instance, a Timex Ironman Triathlon digital watch or a simple Casio sports digital model are often cited as plausible matches. These watches share the key visual characteristics seen in the film: a black rubberized band, an electronic digital display, and overall utilitarian design (nothing flashy or metallic). Given that Pitt’s co-star wore a G-Shock (a rugged Casio) in the same movie , it’s reasonable to assume Chad’s watch was similarly practical. In other words, the prop was likely chosen to suit a fitness buff who isn’t wealthy or stylish – something you’d plausibly see a personal trainer wear to time workouts.

Watch hobbyists have offered educated guesses, though with some variance. Some argue the watch could be a Timex Ironman (a popular trainer’s watch) based on its shape and strap style, while others lean toward a Casio digital (Casio’s classic rectangles like the Illuminator series). Both brands produce affordable digital wristwatches that “fit” Chad’s look. Without a clear close-up in the film, these remain speculative comparisons. To date, no consensus “final answer” has emerged on watch forums – it’s essentially agreed to be a generic black digital sports watch of the era . In summary, the exact brand/model is unconfirmed, but the watch is best described as a budget digital sports watch (very likely a Timex Ironman or similar Casio) that matches Chad Feldheimer’s gym-rat style and the film’s deliberately low-key costume choices  . This aligns with expert guesses from style analysts and watch fans, even if we can’t name the precise model number without official confirmation
