All Navy SEALs used to be issued with a Rolex Submariner, but this tradition became too costly. Now, Navy SEALs do not have an official watch. Still, there are some brand preferences among them, such as Seiko, Suunto, and G-Shock. Watches designed for divers tend to be popular with Navy SEALs because they are usually extremely rugged. A Navy SEALs watch should, above all, be functional and draw attention to itself. The entire Casio G-Shock series of watches are popular among military personnel due to their toughness and durability. Many of the higher-priced models also feature valuable tools, such as compasses, altimeters, and barometers.
