IMHO, no. The white dial and slender markers and hands call for a more formal look. I think a black strap would look better, too. My opinion only, beauty is in the eye of the beholder!
Lug width on the Mark XVI is 20mm. Currently my favorite watch (It will get a Prof 2xar crystal. Then it will be gen IWC dial, hands, crown/tube, datewheel with a swiss ETA2892A2 and amazing crystal).
My dear IW378901 Top Gun, which recently came back from Domi's master hands!
Mods include a Gen Crown & Tube, painted tail on the second hand's plane, relume, and (I believe) correct brass color for the logo.
Next up will probably be a gen crystal along with a gen dial if I can source one!
