MTM Sherman 3-GER - Shemar Moore - S.W.A.T.
It looks like the same watch worn by Dwayne Johnson in Skyscraper, but on a custom rubber strap instead of the original metal strap worn by The Rock.
The Sherman 3-GER is named after the Sherman WWII tank and the unique steel band is styled after the tracks of the tank. Another cool feature is that both the strap and the watch can be customized at MTM.
The watch worn by Shemar Moore seems to be an older model of the Sherman 3-GER, with the yellow MTM logo at the 6 o'clock position (currently not offered anymore) and whiote day/date window.
It doesn't have the 'tank' bracelet, but it's matched with black a rubber strap, the same rubber strap that Shemar Moore also wore with an MTM Falcon watch in previous seasons of S.W.A.T.
