This is only partly true. Yes you'll have to switch over the date wheel and rotor but the bigger problem is the pinion. There are a bunch of different lengths for them and if you get the wrong one you'll need to swap it over from the clone. So far nobody has reported exactly which model of the 2892 has the proper pinion length but I'm pretty sure I read somewhere that someone just swapped the pinion. I get the feeling however that if you are going to the length to get a proper Swiss movement into a rep that has a solid caseback, you want it to be fully Swiss, not a Swiss/Chinese hybrid. Unfortunately, I don't have the information about which one is a plug and play so if you want to want it to be an easy swap, you'll have to do some digging yourself.
