I had an uncle with a gold Timex with the Mickey Mouse face, that had a gold Milanese band. I thought it looked great then, and I still think so today.
The problem here obviously is the finishes don't match. It's not terrible, but it's not great either.
Apple really needs to introduce the $1500 gold clad watch for all those people who won't wear silver, and want something more formal looking than the Sport, which has no matching band lugs at all. Of course that still wouldn't solve your problem as you'd need to upgrade your watch. What is surprising is that Apple almost certainly sells more of the Sport than all others combined, so one would think they would have the greatest number of optional bands available for purchase. Guess they want to force customers who want a better selection of bands to upgrade.
I'm still perplexed that Apple has not offered the 18kt gold link bracelet for the Edition after giving one away to Karl Lagerfeld. I was expecting them to announce it at the September event. So I suppose there's the possibility that Apple may introduce some new bands before Black Friday, though I doubt we'll see the mid-tier gold watch until the gen 2 watch launches.
