Hm, okay that's just a dirty photoshop mockup, but while I love the Mk XV I'd keep it on a black strap. Either black leather or black Nato. Sand Nato might work as well for a cool military look. FWIW, my previous boss used to carry her Mk XV Spitfire on a military green/muddy green Nato (not camou!). It looked stunning. But the Spitfire had a lighter, non-black dial. If you like the Hirsch strap, isn't that one available in 19/16 or what?
