The Rolex Caliber 3135>>>>>>

Hi, nice article, for me there were some new information in it.

Where exactly are the bridges which are rhodium platet - where I made the red circles?

I believe the areas you circled are rhodium plated. Do you believe otherwise?

And why is is the plain sleeve bearing of the rotor a weakness - I thought it's a jewel bearing and that is the reason why it is so silent - I thought that is a strength?

The plain sleeve bearing (which is not the key to the silent Perpetual winding system) must be kept well lubricated - as long as you do that, you won't have any problems. Most manufacturers (including Rolex themselves in the case of the newer caliber 4130) use ball bearings in the winding rotor system, because ball bearings are less dependent on lubrication.

Thank you. The ROLEX concessionaire where I bought my Seadweller eyplained to me why the Rolex Rotor is much more silent than, for example, compared to a Omega watch. And he explained that with the Jewel-bearing of the rotor instaid of a stainless ball bearing. That explanation sounded logical for me.

Maybe he was wrong.......

Yes, I think the 3135 is worth to write about in those kinds of online magazines. The 3135 is technical progress in a reserved way. Like "never change a winning team". Or don't change parts of a system if you are not sure to replace with something much more better. And it works and works like in the advertising of the old VW beetle shown. But it sounds much better than the engine oft the old beetle - if it's comparable...
