Greetings!
What an excellent question! Appearance wise...appearance-wise...appearancewise...among the three, I'd be inclined to go with the hyphenated version! You're right, though, that clockwise doesn't have one, nor otherwise...moneywise I'm less sure of. It's difficult to find answers to really specific questions like these, so all I can do is give you my best guess and tell you that if I were spelling it, I'd say "appearance-wise"--but if I had to justify it, all I could say is "it looks right that way!"
If I find out anything more on this topic, I'll let you know!
Thanks,
