Just so I understand this, in the 321 video by Watch Advisor, they were talking about the relative difficulty and expense of manufacturing column wheels vs cam system. Gregory Kissling said the move to the 861 movement was due to Omega wanting to "industrialise" the chronograph and "increase production" (View from 7:00mins.) This, using other words, seems to be saying the cam system is cheaper/simpler/faster to manufacture than the previous column wheel based system. Are you saying column wheels are similarly difficult and expensive to manufacture or talking about them being similar to service?
