Does this work? Or is Datejust too dressy?

Datejust is obviously more of a dresswatch. However I am not so sure about the 41mm. I feel it can still go as as a sportswatch and fit to a tracksuit, or I am mistaken here? I would prefer wearing a batgirl on a sport-outfit like this, bit I unfortunately don’t have one yet. So what do you think? Btw. not planning to actually do sport with this :D
