3KF Edition — Integrated Steel Bracelet
The 3KF Nautilus 7118/1A-011 stands as the current horological benchmark for the 35.2mm reference. By successfully integrating a true 1:1 clone caliber rather than relying on a modified Miyota base with decorative plates, 3KF achieves the exact 8.6mm case profile of the genuine piece. This eliminates the disproportionate case thickness that plagues lower-tier alternatives, offering collectors a mechanically and structurally accurate representation of the modern Ladies Automatic Nautilus.
Powered by the comprehensive Caliber 324 clone, this movement features a 1:1 split architecture and a fully functional 21K gold-plated central rotor. Unlike standard replicas, it accurately incorporates the correct shock absorber positioning and authentic gear train operation. The movement is finished with accurate perlage and côtes de Genève, delivering reliable timekeeping with a power reserve of approximately 36 hours.
Crafted from premium 316L stainless steel, the 35.2mm case features an alternating satin and high-polish finish that accurately reflects light along the iconic octagonal bezel. The Gray Opaline dial exhibits the correct wave-pattern relief specific to the 7118, complete with a subtle black-gradient rim. White gold-textured Arabic numerals at 12 o’clock and alpha-style hands are uniformly filled with Super-LumiNova for strong low-light visibility.
