So you'd propose jamming the GPS satellite broadcast signals? That would pretty much just break GPS for everything nearby. Or do you mean just outbound communication from wrist devices? How are you going to prevent people from just going home with their Apple/Garmin watches and connecting/uploading from there (which is, presumably, what they already do)?

For a military operational area? Quite frankly I'm surprised that GPS signals aren't jammed today. At the very least, with the advent of cheap drones, and the dangerous payloads they can carry, I've got to believe that it will be forthcoming soon, regardless of the loss of intel that can be occurring.

The military created GPS. It wouldn't be very productive to jam their own signals on their own bases.

Military bases already have rules covering use of electronics like laptops, cameras, and phones, so adding smart watches to that list isn't very surprising.

The military uses a different GPS frequency than civilian gear.

Computer vision is becoming cheap and ubiquitous. The need for GPS is probably diminishing for this kind of application.

There are multiple GPS, you need to jam all of them.
