Complications are small visual elements that appear directly on the watch face and convey important information to the user. Complications are automatically visible whenever the user looks at Apple Watch to check the time. Most watch faces support at least two or three complications, and the user can customize which complications are displayed. Apps may use a complication to display app-specific data.

So, you must have four extras installed that are showing you something when you glance at the watch. Maybe they have always been there so you don't actually recognize what they are? Try removing them and see what changes. I know my Pebble also supports complications, but depending on the watch face they may or may not actually show up. You could also try switching to a watch face that supports (a certain number of) complications.
