A while ago I posed the question, but nobody has answered it:
richardmille.watchprosite.com
Now that I'm seriously considering getting a RM004, I'd first like to know the answer. Is anyone familiar enough with the RM004 movement to be able to answer this question? If not, maybe someone can contact Richard Mille to get the answer.
If there is no isolation mechanism, can Richard Mille please explain why? While it is my understanding that lack of an isolation mechanism in a split second chronograph is a major shortcoming, perhaps the RM004 design made an isolation mechanism unnecessary.
The isolation/disengagement mechanisms of other split second chronographs are easy to find on the internet. The lack of any information on the RM004's isolation mechanism makes me suspect it doesn't exist. The isolation/disengagement mechanism used in the Patek 5004 is mentioned here:

and the isolation/disengagement mechanism of the Lange double split is discussed here:
