Patek Philippe Nautilus 5811 41mm 3KF Blue Dial

Every millimeter of the Patek Philippe Nautilus 5811 41mm 3KF Blue Dial has been reverse-engineered by 3K Factory (3KF) using genuine reference schematics. Featuring a 41mm case crafted from solid 316L stainless steel, colorless anti-glare sapphire glass, and the ultra-thin 1:1 cloned Calibre 324 SC / 26-330 SC automatic movement, this 1:1 Super Clone offers genuine slim case proportions, a 21K gold-finished engraved rotor, and exhibition caseback beauty.

Inside the 41mm Case & Movement Engineering

Cheap replicas often give themselves away through cloudy crystals, incorrect case thickness, or rattly bracelets. On this 3K Factory (3KF) edition of the Patek Philippe Nautilus 5811 41mm 3KF Blue Dial, the sapphire crystal is treated with colorless anti-reflective coating for distortion-free legibility, while the 41mm solid 316L stainless steel case and matching bracelet and precision-machined folding clasp reproduce the exact weight balance of the original.
