Hamilton Jazzmaster Seaview Chrono Quartz - John David Washington - Tenet
The Hamilton watch can be spotted in several scenes in the trailer and he seems to wear it a lot, although we have to wait for the final movie to see how much screentime the watch will get.
Other watch in the film
In the same film John David Washington also wears a specially modified Hamilton Khaki Navy BeLOWZERO prop watch, with digital screen. A version of this watch (without the digital screen) has been released as a limited edition, read more on WatchID or visit the official Hamilton TENET website.
