This is a genuine Oris steel deployment clasp. This clasp will fit a strap that is 18mm wide at the clasp end.

This will only fit a rubber deployment strap. It can not be used with a leather strap.

I have given you photos of your watch clap from every angle. Please use them to add to this description.

If you are not sure if this will fit your watch or if you have any other questions then message me. I'm here to help you.
