ROLEX shock ring U.S. Patents

While doing Rolex movement research on shock resistance,
I discovered an article in A Blog to WATCH stating that Rolex Montres
had applied for patents in the U.S. covering a "shock ring".

In addition to providing a greater resistance to shock,
the ring patents appear to offer ROLEX:

1. Easier internal movement mounting within the case. Non-traditional
non-screw based mounting assembly may be possible.

2. More efficient factory assembly of the movement within the oyster case.
(This shock ring system appears to be more potentially useful within the larger 40mm Rolex case)

Have any of our technical staff learned of these alleged USA patents
by Rolex? The article was detailed enough to provide diagrams and
appeared genuine. However, would like some other informed confirmation.

Thanks in advance to our folks.......

I remember reading it a while back.

Other brands have gone as far as releasing models with the movements fitted within shock dampeners. My opinion is it is too soon to gauge if there is a statistically significant improvement in real term protection as there haven’t been enough of them in circulation for long enough. The theory sounds good I guess.

It is possible Rolex could go this way in the future; but anything is possible. A flick through their patents will show countless designs that never made it to production, but it doesn’t hurt their bottom line to patent things they never use.

The Junghans "Trilastic" approach was implemented by them years ago, but is no longer used. Possibly their move from in-house to third party movements triggered its end. Was an interesting arrangement - the complete movement suspended inside the case at three (presumably flexible) points.

No idea how effective it was at limiting shock damage as they all - or at least all I've seen - had conventional balance shock protection as well.
