Well, a lot... I was able to buy a 6263 T SWISS T dial 2y ago for 6k USD I think. I've inquired to a few guys I know and a service dial is going around 6k €, I've had 2 prices of 18.5k € and even 38k €... Offcourse for NOS dials.
Great projects! I was able to get a set of gen parts (T21, P302 pushers, crown, tube, all hands) at a great price so going with them.
But to me the pushers of MQ and Phong look great vs gen and seem to a better alternative vs cousins. Although cousins is cheap offcourse.
It all depends on how close you want to get your build I guess? I prefer the original look with P301 MKII pushers for my build and would consider the Phong/MQ ones. I do have gen P302's for now though.
These are interesting builds, hehe.
