This is a listing for a silver-colored, ladder-style Omega OMEGA buckle. It's from around the 1970s. Perhaps this is the last of the interesting Omega buckles? After this, they just became buckles with the Omega mark engraved on them, which is less exciting. Why not try it with a vintage Omega watch? It has been cleaned after acquisition. The buckle side is 14mm, so it should fit bands with a lug width of 18mm. Thank you.
