Zac Efron wears a watch that looks like a two-tone gold Rolex Oyster Perpetual Datejust in the movie Dirty Grandpa, but the brand is not yet confirmed.

The watch has a fluted bezel, steel case, gold and steel Jubilee bracelet, ivory coloured dial, date window. The date window in the movie looks different (wider) than the Rolex Oyster Perpetual window, so a better image from the film is needed to confirm the brand of this watch.

In the same film, Robert De Niro wears a Tag Heuer Aquaracer watch.
