With regards to building... I do indeed have $3k+ into each watch. Yes, folks, that's each (total is $6k and change between the two). Sounds like a lot... And it is. But considering that these frankens have genuine El Primeros inside, along with a number of genuine parts, I personally feel that having a 1:1 with gen for a fraction of the price is worth it (standard 16520's are now selling at $9k - $11k, depending).
