Ummm... and Apple Watches are the epitome of high fashion? I don't think this is a strong argument when directly comparing these two things. Fwiw, I have met quite a few watch enthusiasts who wear a mechanical watch on one wrist and an Apple Watch on the other. This seems natural, honestly, since the primary function of an Apple Watch is definitely not to tell time.
Well, they look like sport watches.
People can choose the aesthetic they want, but you're sending a message with one that's that opinionated, which I don't particularly want to.
