I've got my Caribbean blue Tsunami on an orange isofrane now and the color combo is spot on. But since the Tsunami head isn't that weighty, the isofrane sort of takes the watch over (too much strap for the watch). I've tried searching for some other 22mm orange straps and haven't come up with much.
I've seen a 24mm Bonetto Cinturini strap that looks good - thick, vanilla scent - but it's obviously the wrong size.
Then there is the Omega style 22mm orange, but it's curved at the end.
If timefactors had their retro strap in orange, I think that'd be it, but they carry only in black. They do have another orange in silicone that doesn't look bad.
What haven't I seen/considered?
Will post pics soon of my current set up.
