The price doesn’t match gen too.
If you like the watch, don’t be too pedantic about the differences in details. Anyone knowing the gen 15407 (meaning anyone who spends 5min studying pics of the gen online and compares it with the rep) will be able to know the rep isn’t a gen even if the balance wheel is 1:1. It’s just something you purchase to wear for fun. If you want something accurate for a watch of this level then only the gen will do. You’re talking about a >$100k watch and this caliber of replication is already applause-worthy priced at this level.
Reps will always be flawed and especially reps of high end gens like this 15407.
