Help required about my WG Daytona 116509 bezel

[GolfPunk]

I have an M serial White Gold Daytona purchased in April 2009. It has the button clasp oyster bracelet and not the latest style clasp.

The bezel on my Daytona needs replacing as the engravings are too shallow and the black paint is almost missing.

Ive attached pictures of my new bezel. Could any experts look to see if this will fit my Daytona please?

The reason I ask is I understand that at some point between 2004 and now, Rolex changed the bezels on white gold models to prevent people fitting them to stainless steel 116520 Daytona's. Does anybody know exactly when this was?







Here is my watch with current bezel;
