Tons of options > I think you may have mentioned you don't like Nato/Zulu. If that is the case I would pick up one of these type straps and maybe add a bronze buckle or stay with the brushed SS.
The same seller below has the buckle and the straps. One thing to keep in mind if you buy a buckle make sure the buckle side is correct . Some will taper to 18mm and some are straight 20mm on lug and buckle ends.
