Speedmaster Rubber Strap (19mm) - what watch will it fit?

Hello gang - so I recently sold my Speedmaster Racing watch. When I bought it, I purchased the OEM specific rubber strap with deployant that came with those models from Omega. I did not sell the strap with the watch so now I am looking for what watch it would actually fit on. I assume any 19mm lug width watch but wanted to ask - is only the Speedmaster racing line take a 19mm strap? Any help is appreciated!
