I imagine it's because they need to put something on the area around the screen, otherwise it would look weird. Casio do make plainer variants of their watches so you can see what I mean: https://us.firstclasswatches.com/casio-black-382mm-digital-d... . It just kind of looks empty. The F-84W has stuff around the screen but is a bit more understated compared to the F-91W: https://i0.wp.com/centreseconds.com/wp-content/uploads/2019/...
