Casio G-Shock GA2100-1A1 - Taylor Kitsch - The Terminal List
The Casio G-Shock GA-2100-1A1 has an all-black face and case with only the hands in grey.
The black analog / digital watch in the series is fitted on a green and black nylon rope watch strap. I haven't been able to find the exact paracord strap - send me a message if you have found the exact strap.
The most similar strap as suggested by Josh is this green Survco Tactical SRV01G Para Cord Watch Band on Amazon ($21) also available in Black, both pictured below:
But similar straps can be found on eBay. Another very similar strap, as suggested by Alex, is this paracord strap for a Garmin watch. You might also need a (Jays & Kays) strap adapter kits for the G-Shock, which allows the wearer to mount 20mm (or 22mm) straps to the GA-2100 in lieu of the stock integrated resin bracelet.
The watch itself is available for $99 on Amazon.
Taylor Kitsch stars together with Chris Pratt in The Terminal List. Kitsch plays Ben Edwards, a CIA Ground Branch operative, who is a former Navy SEAL and James Reece's (played by Chris Pratt) former teammate and BUD/S classmate.
