This is fitment for a strap I found on ebay (seller is in the UK ,45 pounds, ships to US) - they have a bunch of colors. I bought not knowing how it would fit seeing as how it was cheaper than most AP rubber straps, turns out they are rep straps (branaded & branded buckle) even though the listing doesn't show that. This is a JF 42mm ROO case, and an XF diver case - on both cases the fit is very very snug, you actually have to work a bit to get the screw/bar back in because it's so snug.
seller is amg.13
