Richard Mille and many other use the same chrono module. The roc uses an f Piguet movement which is different. AP will have an all I house chrono of this calibre in less than 2 years. I was told next year . The diver chrono is all in house but there is no date and no vertical clutch. I can't recall if there is a column wheel. Someone please correct any errors.

Looks good. AP did use JLC movements when they owned a 40% portion of the company. The movement was a joint effort between AP, Patek and Vacheron but AP got the rights to it so they can still use it today. So at a time I would say the JLC movements were somewhat in house. Kind of like APRP is in house today.

I don't think the diver chrono is all in house. It's the same 3124 that's in the Jules audemars chrono that was recently discontinued. It's based on the 3120 but has the chrono modual. You can tell by the crown and pushers not lining up. Pure speculation but....I would think when AP releases its new in house integrated column wheel chrono we will first see it in the ROC and Jules audemars lines. I actually think they will keep the modular chrono in the ROO for awhile. The ROO has always had a modular movement and the size of the case isn't an issue for the thicker movement. The ROC would benefit from an in house movement and the Jules audemars line needs something to spark it back to life.
