This is an original Cartier crocodile strap for a Cartier wristwatch, 16mm wide at the Van Cleef lugs and 14mm wide at the deployante buckle.
The two separate straps are:
1) 99mm long with 16mm Van Cleef lugs end
2) 85mm long with 14mm deployante buckle (rounded pointed end)
I give 100% warranty this is AN ORIGINAL CARTIER STRAP.
