I suspect people are downvoting because they're imagining the older style of watch band spring bars. The older ones like this [1] require a tool, dexterity, and also some luck that it doesn't go flying across the room.

Bands with the newer style like this [2] can easily be done without tools or any stellar dexterity, but are still a bit more fiddly than how it seems Apple watches are. I'm betting this is the type you're talking about, as it's the only kind I've had to deal with across my ~decade of smartwatch use.
