Chris Pratt wears a Casio G-Shock

Chris Pratt plays Owen Grady in Colin Trevorrow's Jurassic World (2015), a former Navy animal behaviorist who trains velociraptors through patience and structure. Rick Jaffa, Amanda Silver, and Derek Connolly wrote the script. The park's corporate side keeps pushing for bigger, scarier attractions. Grady keeps warning them it will go wrong. It goes wrong.

Grady wears a Casio G-Shock GD100-1B, confirmed by Wrist Enthusiast in their feature on the watches of the Jurassic franchise. He wears it upside down on his right wrist, a reading habit common among soldiers and outdoor professionals. The GD100-1B is one of the larger G-Shock models: matte black resin, oversized LCD display, 200-meter water resistance. Casio introduced the G-Shock line in 1983 when engineer Kikuo Ibe set out to build a watch that could survive a 10-meter drop; the GD100 is among the more stripped-back entries in the current lineup.
