3KF Edition — Integrated Steel Bracelet
The 3KF edition of the Nautilus 5711/1A-011 represents a significant technical milestone in replica manufacturing, primarily due to its case profile. By developing a fully integrated clone movement rather than relying on a modified base caliber, 3KF achieves the exact 8.2mm thickness of the genuine article. This specific iteration is widely recognized on collector forums as the structural benchmark for the 5711 reference, weighing in at a confirmed 114.6 grams.
Powering this timepiece is the 3KF Super Clone Caliber 324. Unlike traditional replicas utilizing decorated Miyota movements, this caliber features correct bridge architecture, a visually accurate balance wheel placement, and proper perlage finishing. In accordance with the genuine 324 caliber specifications, it features a unidirectional winding mechanism and delivers approximately 36 hours of power reserve.
The case is machined from 316L stainless steel, exhibiting the complex alternating brushed and polished finishing intrinsic to the Nautilus design. The dial features the signature horizontal embossing in a crisp white tone, contrasted correctly by blackened gold applied hour markers and hands. This high-contrast configuration ensures excellent legibility while maintaining the distinct porthole geometry of the bezel.
