This is going to burn the gen folks, but its true.
The printing on the VSF is better. See those right angles formed by the vertical and horizontal strokes in the E? They should be right angles - just like the VSF shows. The Rolex dial print is blobby - usually caused by too much ink on the pad.
There are rumors that it is intentional for Rolex to make their dual printing bloody and crooked as an anti-counterfeiting measure.
