Reg,
A Vogard F1 Black with a black strap is for me the perfect combination! I do wish I'd bought one.

I have bought a couple of watches from Marcus and still have my Hublot Big Bang AeroMax version which came from them, though I rarely wear it...
I've seen the IWC World Timer and it could well be the same complication, but I await Stuart's input from his library of watch info! Even if it is the same complication, I do prefer the Vogard...
