I'm considering getting the QuickFit 22 black silicone band and can't tell from the website whether the buckle is slate (color of 945 buttons and buckle) or black. The description says 'black/black' but the buckle looks a bit lighter in the pictures than the ones on the other silicone band colors (which look truly black) and it says it's for the F5, which had a slate bezel. Does anyone know?
