I ordered a Fluco Horween Shell Cordovan strap on Amazon. It is a deep brown colour with a nice sheen. The leather is flexible and sturdy. Apparently Fluco make all the straps for Nomos so the quality is excellent. I kept it on the normal tang and buckle, since for me they are more comfortable than any deployant buckle I've tried.
I got the style with matching stitching and some padding on the ends that attach to the watch. So far after a few hours only, it is quite nice to wear and already starting to hold a curve to my wrist. I think it fits a more casual attire compared to the JLC black alligator strap.
