Just a standard Timefactors aviator but with a black buckle. (check the reflection of the symbol :D )
Same strap I had on the Zeno. It started with a black buckle too.
Had loads of wear out of it, so I had to get a new one for the CAF.
Here a black studded one.
The red studded ones were amazing but I am going to stick to plain black for the CAF.
