The watch has its own Location Services switch at Settings › Privacy & Security › Location Services, and Apple says the privacy settings you change on the paired iPhone are applied to the watch as well. Sharing your location with people is a different switch again, and it belongs to your Apple Account rather than to the watch. Apple documents that when a cellular Apple Watch is sharing and the iPhone is not with you, Find My shows the location of the watch.
Do they get told?Whether anyone is told that you turned Location Services off on the watch is not documented on Apple's page. What is documented is the effect on the watch: apps stop getting your position from Location Services, and Apple says location may still be used for emergency calls.
