This is an authentic Omega De Ville Prestige men's steel watch bracelet (Omega reference number 1507/834) that was removed from a new watch. It is made from polished stainless steel.
Your watch strap is 19mm wide where it connects to your watch and is 15cm ( 5 7/8 inches) long. However this can be shortened be removing links.
If your clasp has the number 834 on it then this bracelet will fit your watch.
I have given you photos of your watch strap 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.
