The problem with even the Vaucher is that it was still reworked and extensively modded in China just like the clones, and while I'm sure they're awesome, they're effectively unrepairable and the price premium is completely insane. Quite honestly factory movements are probably always the better buy just since they're made in actual factories, which implies that parts are being made on a scale that you can actually get them. If this thing ever goes out, you've got yourself a $30k paperweight. If you're dedicated to chasing the 1:1 I guess it makes sense but the whole value proposition of reps peters out the closer you get to "normal watch" prices IMHO.
Keep in mind the reason for the premium is the thief’s selling these Vauchers as gen in the gen market.
Crazy crazy stuff.
