Yup, the company who makes the trick springy, flexy classic watch band (that may or may not be a hair-puller) that was on my dad's Omega for forty-odd years has designed a version for the Apple Watch.

It's got a brushed finish like Apple's own Link bracelet, uses the same type of adapters that Apple uses for their Classic Buckle straps, and seems appropriately sized for the AW's width.
It still can't be easily resized, though, but I guess it can be done with the right tweezers and plenty of patience. More expensive than typical Speidel bracelets, too; but still, this setup saves the effort of buying a different Speidel bracelet and sourcing other adapters, and probably costs about the same.
