cib0rgman Posted May 24 Report Share Posted May 24 I don't think there is noob version of this. there are other version with a 4130 decorated as a 4131 with updated rotor Quote Link to comment Share on other sites More sharing options...

freddy333 Posted June 1 Report Share Posted June 1 Shortly after I installed the gen balance, I also replaced the rotor, which includes the bearing. The 1st pic is of the Big Kahuna's original A4130 rotor/bearing. The 2nd pic is the gen 4130 rotor/bearing. As you can see, both 4130 rotors contain 7 ball bearings. The only difference between the rotor bearings is that the tiny tabs that retain the bearing race (where the balls circulate) is more visible on the gen when viewed under magnification. Other than that, I do not see much difference other than the slightly smoother finish on the gen metal surfaces. But, unless you see them side by side, I doubt you could tell the difference anyway. However, the new 4131 contains what Rolex calls an 'optimized' rotor/bearing, which contains 40 or so ball bearings & a different bearing race. Alot of people, who have only seen the current 4131 rotor bearing, think the A4130's rotor bearing must be an 'obvious tell' of fakery because it has only 7 ball bearings, unaware that that is actually correct for the 4130; only the current (4131) movement has the 'optimized' rotor/bearing. As to the A4130's rotor being 'loud' -- that has not been my experience. Certainly, in comparison with the old secs @ 6 7750 Daytonas, the A4130 is nearly gen quiet. Shaking an A4130 will not give you away like some of the old 7750s often did. Only with your ear right up to the caseback can you hear a difference between the A4130's spinning rotor & the gen's (& the subtle difference may simply be due to a lack of proper oiling by the factory). Unless you plan to install a display caseback (as I did), I would not worry about the A4130's rotor/bearing. Quote Link to comment Share on other sites More sharing options...

cib0rgman Posted June 7 Report Share Posted June 7 so what is the difference between DD4131 and SH 4131 and i guess Noob 4131 Quote Link to comment Share on other sites More sharing options...
Ronin Posted June 7 Report Share Posted June 7 DD = Dangdong and are now considered the best option. SH less quality. Noob is usually poor quality and less compatible with Gen parts. That is my experience with their 32xx movements anyways. I'll defer to Freddy333 w/r/t the 4130. Here is a good comparison of the 3xxx's which I am guessing translates to 41xx to some degree: Quote Link to comment Share on other sites More sharing options...
