【Bozwatch Top Customized】-Patek Philippe modified free-sprung double‑P 324 movement (for 5711A / 5711R)
1-Modified with a free-sprung weighted balance (adjustable screws)
2-Movement re‑finished with gilt engraving
3-Fitted with an 18K solid gold rotor
This is a modified free-sprung double‑P 324 movement designed specifically for Patek Philippe Nautilus 5711 models – available for both the 5711A (stainless steel) and 5711R (rose gold). The movement has been upgraded with three key modifications that enhance both performance and visual authenticity.
—The balance system has been modified with a free-sprung weighted balance featuring adjustable screws. A free‑sprung (non‑indexed) balance does not use a regulator arm – it is adjusted by turning the weighted screws on the balance wheel. This matches the construction of the genuine Patek Philippe 324 caliber. The adjustable screws allow for fine regulation and provide a more authentic appearance when viewed through the caseback. This is a significant upgrade over standard clone movements that use a traditional regulator arm.
—The movement finishing has been re‑finished with gilt engraving. Gilt (gold‑toned) engravings on the bridges replicate the aesthetic of the genuine Patek Philippe 324 movement. The re‑finishing process may also include Geneva stripes, polished beveled edges, and enhanced bridge decoration. For buyers who display the watch with a transparent caseback, the visual quality of the movement finishing is a key part of the ownership experience.
—The rotor has been fitted with an 18K solid gold rotor. The genuine Patek Philippe 324 uses a solid gold central rotor. A solid gold rotor provides authentic weight, color, and visual appeal. This upgrade significantly improves the appearance of the movement when viewed through the caseback compared to standard steel or plated rotors.
—Who is this for? Collectors building or upgrading a Patek Philippe Nautilus 5711 (either steel or rose gold) who want a modified 324 clone movement with three premium upgrades: a free-sprung weighted balance, gilt re‑finishing, and an 18K solid gold rotor. These modifications bring the movement significantly closer to the appearance and construction of the genuine Patek 324. For buyers who care about movement aesthetics and performance – and who want the correct free‑sprung balance and solid gold rotor – this modified movement is a strong upgrade path for 5711 builds.
