I want to put my Seiko Black Series (SNE493P1, which is 20mm, and SRPC49K1, which is 22mm) on Cordura straps, which I find more comfortable than the silicone that they came with.

Given the watches that are in it, I'd ideally like the straps to also have black buckles, but my google-fu can only seem to find black Cordura straps with steel buckles.

Does anybody know a source of black Cordura 2-piece straps with black hardware?

(Any suggestions about putting them on a NATO will be politely ignored ).
