Looking for replacement band for 1945 rolex watch

I have a 1944-1945 oyster perpetual Rolex watch. It is a 3/4 size (16mm) I am looking for a rolex watch band to replace the "non-rolex" band that is currently on the watch. Could you please steer me in the right direction or let me know how much one would cost. It is a stainless steel watch / band that I am looking for.

Thank you for your time
