Edits made by you show up in the watchlist even if you were the last person to edit it. This is annoying since you can't easily distinguish between yours and someone else's edits.
There already exists settings for hiding own edits from the watchlist. Go to [[Special:Preferences]], and flag "Hide my edits from the watchlist" on the Watchlist tab.
