Because samsung seems to be unable to provide a flawless OS experience, it is now and then sadly time to reset my watch. Personally I find it completely annoying to lose all my settings, just because Samsung things there should not be a manual backup button.
There is absolutely no reason, to force me to wait until Samsung decides to automatically backup the watch whenever..., just to allow me reset my watch with the current data, because Samsung messed something up it the first place ... and forces me to reset a 220$ Watch5 because it runs very poorly.
My current experience with Samsung and the Samsung Watch5 is very disappointing!
Never had issues like that with apple. All I can currently say is: DONT BUY
