Genuine Jubilee Bracelet?

[Paul Raposo]

Hello Everyone! My first post as a new member and I had a question about this Jubilee bracelet.

I've seen the other threads here that discussed Jubilee bracelets, but looking at this one I can't decide if it's genuine Rolex, or not.

I've included a pic of the clasp and markings. It's a steel bracelet with the end pieces marked 555.

One thing I noticed is that it says Registered, but does not have the word Patented & Registered.

Any input would be greatly appreciated. Thanks all
