Interesting. So would a mechanical watch be ok, but an electronic one not ok?

An electronic watch is ok. Just not with cellular, wireless or bluetooth, USB capabilities.

How would you tell? Assuming someone's being sneaky, that is.

WIDS or some other spectrum monitoring; or random physical checks. But mostly policy controls and background checks.

You can be sneaky sure, but that what background checks are for - to see if you are a trustworthy individual.
