There have been a number of posts about this subject. Here are my questions.
Do all GMT 2 C have 3186 movement.....or does it matter if it is an m or v or z. Also what is the actual difference between the 3185 and 3186. Is it just the hairspring. Please share your thoughts...opinion and knowledge on this issue. |

Thanks....this leads me to another question. In the new dj ii or dd ii do they employ the new hairspring? Have they changed the name of those movements.

Likewise, the one in the Day-Date II is the 3156, as opposed to the 3155

All GMT2C has the 3186. The mentioned 3136 has the new balance spring, but also a new date disc, for the larger DJ2. The DSSD has the PB, but the caliber is still called 3135, since there are no other changes. The Milgauss has caliber 3131, with the PB, but also some other changes to improve its antimagnetic properties. Best, A |

Much of the Rolex line is now using the in-house spring though. Milgauss DJ II DD II Yachtmaster II DSSD GMT II Sub ceramics Explorer II I expect that by the end of this year, almost all willl be retrofitted with it..

You guys are all amazing. Thanks so much. So what exactly are the benefits in real world usage to these changes being made.

I would say that Rolex invented the PB only to be able to insource the balance spring. Up till now (and still for the 3130, 3135, 2235) the balance spring is manufactured by Nivarox, a company owned by the Swatch group. Nivarox is also a patented alloy, which have been used for many years. I do not know if PB is better than Nivarox, but of course Rolex claims so. I have noted though that my PB based watches are more consistent (for example loosing or gaining the same amount of time every day), whilst the Nivarox based are slightly easier to adjust be help of position. (Minor issues, really - all are well within the COSC limits.) Best, A |
