CNC original‑data developed case, upgraded with a genuine 240 movement.
The build featured a CNC original‑data case and a genuine Patek Philippe 240 movement (the ultra‑thin automatic with 22K gold micro‑rotor). The use of a genuine movement sets this apart from most custom builds, which often use custom‑molded calibers. This makes the watch extremely close to the factory 5712A in both appearance and performance. The sale indicates strong demand for such high‑authenticity builds. Congratulations to the buyer – you’ve secured a top‑tier piece.
