This is a BK's answer to movement question at RG
"Yes, these come with 2678-2. 2678-2 is indeed a smaller movement used in ladies' watches. It's in no way an inferior movement. It has the same beat rate and power reserve. The plus is there's no chance for it to be a fake ETA 'cause none exists for 2678-2. wm9 will ensure the overall weight of the watch is as close to gen's by use of a proper weighted movement ring, no less than other versions with 2836-2. I'm also hoping 2678-2 has better, more even datewheel because I have seen enough 2836-2's that don't have every date square in the date window."
