This is a full‑modification specification for a Patek Philippe 240 movement – a high‑grade clone designed for Nautilus builds. The description highlights specific finishing details that distinguish this movement from standard modifications on the market.
The gear train features circular brushing – a finishing technique where concentric circular patterns are applied to the gear train components. This is a refinement beyond standard movements, which often have simpler or no brushing.
The balance system is free-srpung (free‑sprung) with four weighted gilt balance screws – matching the construction of the genuine Patek 240. Four weights provide fine regulation and a more authentic appearance. The rotor is a 22K gold rotor – providing authentic visual weight and color when viewed through the caseback.
The bridges feature gold chatons (gold‑colored jewel settings), C‑slot screws (a specific screw head shape used in high‑end movements), deep large jewels, and hand‑finished Geneva stripes on four bridges. Geneva stripes are a hallmark of high‑end Swiss movement finishing. Hand‑finishing ensures the correct depth, spacing, and direction of the stripes.
The jewel holes have mirror‑polished countersinks – the recessed areas around each jewel are polished to a mirror finish. The bridge edges also have a mirror‑polished finish – a labor‑intensive detail that adds visual depth and reflects light. Mirror‑polished edges and countersinks are characteristic of high‑end movement decoration.
Who is this for? Builders and collectors looking for a top‑tier 240 clone movement with finishing details that go beyond standard modifications. The combination of circular brushing on the gear train, free-srpung balance with four gilt weights, 22K gold rotor, gold chatons, hand‑finished Geneva stripes, and mirror‑polished edges/countersinks places this movement at a premium level. For buyers who want movement finishing that matches the quality of the exterior, this full‑modification 240 delivers.
