This is a top‑tier custom build of the Patek Philippe 5712R Nautilus in the leather strap version – a rose gold reference that combines the luxury of precious metal with the classic, refined aesthetic of a leather strap. The 5712R features a complex dial with power reserve, moon phase, date, and small seconds, making it one of the most visually rich Nautilus references.
—The case and clasp are CNC‑machined from original specification data using 18K solid rose gold. Not plated, not wrapped – solid gold throughout. The warm rose gold tone and substantial weight are authentic to a genuine precious metal Nautilus. The case follows correct Nautilus proportions, including the octagonal bezel, “parrot beak” side profile, and integrated lug design. The leather strap is paired with the solid gold clasp for a refined and comfortable fit.
—The dial, hands, and moon phase are top‑tier aftermarket components developed from original data. The 5712R dial features the correct warm brownish‑grey “chocolate” sunburst finish with subdials for power reserve (10–11 o’clock), date with pointer hand (7–8 o’clock), small seconds (4–5 o’clock), and a moon phase display near 7 o’clock. The moon phase disc color matches the dial. Hands follow genuine proportions. Aftermarket components at this level are designed to be visually indistinguishable from factory parts.
—The movement is powered by a custom‑molded integrated non‑indexed 240 clone. “Non‑indexed” means a free‑sprung balance with no regulator arm – matching the construction of the genuine Patek Philippe 240 caliber. Features include gilt (gold‑toned) engravings on the bridges and a 22K gold micro‑rotor. The custom‑molded integrated design ensures correct movement thickness, proper hand stacking, and reliable operation of all complications (power reserve, moon phase, date, small seconds).
—Who is this for? Collectors who want the complex 5712R Nautilus with the classic leather strap configuration – a refined alternative to the full gold bracelet. The solid rose gold case and clasp provide authentic weight and warmth. The leather strap offers a more traditional, dress‑oriented aesthetic. The non‑indexed 240 clone movement with 22K rotor delivers high‑grade finishing and reliable complication operation. For buyers who want the full 5712R experience – including the power reserve, moon phase, and date complications – in a leather strap configuration, this top‑tier custom build delivers a complete package.
