The haptic feedback in the Apple watch is not like the devices found in the Playstation 4 or Nintendo controllers. (Can't speak for XBOX One, sorry.) It feels like a tap, as opposed to the vibration motor modern game controllers use. The practical difference is that in a very short space of time you can count how many times you've been tapped. The vibration motors take long enough to spin up they're very sluggish in comparison, at least in the case of counting the actual buzzes.
I'm too lazy to look it up but I vaguely recall a lawsuit that affected the XBOX and PS2 for the vibration motors in their controllers, but it didn't affect Nintendo because they actually use a different configuration. If memory serves that fueled the rumors that the real reason the PS3 didn't originally have rumble in their controllers was to avoid further litigation. (They claimed it interfered with their SIXAXIS sensors, but the Wii controller showed that was bunk.)
