Cheers Paul,
I have come across some SAAF examples online with the AF markings - it's the closest I've seen, but still not the same.
The Heuer is a Lemania driven watch, but I don't think that's enough of a connection really.
Thanks for digging around for me.

I've fired off a few emails, to the Israeli Air Force Flight Academy & the IDF, I've no idea if they'll get back to me, but I'll post any useful response here.
