3K Factory (3KF) Edition — Tropical Fluoroelastomer Rubber
3K Factory (3KF) has established the benchmark for the 42.2mm Jumbo Aquanaut reference 5168G-010. By engineering a true 1:1 integrated caliber rather than modifying a base Miyota, 3KF achieves the notoriously difficult 8.3mm case thickness, matching the genuine white gold profile with precise 98g weight distribution.
Powered by the 3KF custom Caliber 324 SC, this mechanism replicates the exact bridge architecture and gear train positioning of the genuine. It features a gunmetal-finished balance wheel with faux variable inertia weights and operates at a smooth 28,800 vph. Power reserve is approximately 36 hours.
Constructed from 316L stainless steel, the 42.2mm case features precise vertical brushing on the bezel face with high-polished chamfers. The dial accurately captures the matte Khaki Green geosphere embossing, complemented by white gold-toned applied numerals and upgraded pure white Super-LumiNova.
