I probably got way too ahead of myself, but once I decided on the Apple Watch Sport in Space Gray a couple of weeks ago, I started looking outside of Apple for strap options. I own a couple of IWCs, Panerai's and Rolexes and a custom straps for almost all of them, so I thought I would reach out to my custom strap maker (Greg Stevens Design) and see what he had that might work. I decided on the strap below, except with a black PVD thumbnail buckle. Even after I purchase a strap adapter (personally going with Click although there are a couple other options), I'll be out just a hair over what Apple charges for its leather loop. A nice strap can last a decade so why not invest in something that isn't going to go in the drawer once the new iteration of the Apple Watch comes out in 1-2 years. Just my $0.02.
