FactoryProbableWhole production
Component positions, bridge shapes and train layout corresponding to the published movement. Because the movement IS the dial, this comparison can be made directly and completely from the front.
Generic movement behind a skeletonised dial
CounterfeitProbableWhole production
The substitution this construction makes almost impossible: a different caliber has a different shape, and the shape is what the buyer is looking at. Where a skeletonised watch's visible architecture does not match the published caliber, there is nothing to explain it away.
