I assume you mean the crown (as there is no pusher). The position of the crown is in fact the same as the gen, as a trip to the manufacturers website will show you.
The differences of my V1 U2 rep to the real deal are
1.) Datefont - less bold (like 99% of all reps - can be corrected)
2.) Color of all red markings and the second hand/GMT hand is a bit darker than on the gen (can't be corrected)
3.) No Ar Dehumidifying capsule (below the 6 marker - can't be corrected but can be faked)
4.) Slight difference between rep and gen bezel printing (gen bezel fits rep so can be corrected)
5.) The rep rubber strap is a dust collecting pos (gen strap or other aftermarket strap fit, so can be corrected)
Non visible differences:
1.) Gen: case made from German submarine steel / rep: no submarines hurt in the building process.
2.) Rep coating is only PVD / gen is tegimented PVD so it will last much longer
3.) Pressure Resistance: Gen = 2000m / Rep = mine has been tested to 50m
4.) Anti Magnetic: Gen = yes / Rep = no
5.) Temperature Resistance Technology: Gen = yes / Rep = no
6.) Low Pressure Resistance: Gen = yes / Rep = no
7.) Movement: Gen ETA2893-2 (Swiss) / Rep ETA2836-2 (Asia clone)
This is a pretty good visible replication of the real watch, of course lacking all of the goodies "under the hood". Then again, it also lacks 90% of the gen's price. For me, it's among the definite keepers.
