What sort of bands do you want to wear with a sport watch?
The sport and nylon bands should look fine. So should the leather loop bands (no lugs).
Any of the others will be iffy. Some people wear them with mismatched lugs and love it. I'm not a fan.
I'm not really a fan of the silver aluminum watches with the lugs that are stainless, either, really.
I don't mind buckles on the opposite side of the band not matching. No biggie there.
Were you wanting to wear this with classic buckle, milanese, etc?
If so, they do make gold knockoff milanese bands. You could possibly try that route.
I'm considering a Rose Gold sport this time around (my first gen watch is stainless steel) and I won't be wearing any of my bands that have stainless lugs with a sport watch. I'll stick to my sport bands, nylon bands, and leather loops.
