3KF Edition — Integrated Steel Bracelet
The 3KF 5711/1P 40th Anniversary edition stands as a horological benchmark due to its bespoke movement architecture. Unlike earlier iterations relying on modified base calibers, this release achieves the elusive 8.5mm case thickness, directly addressing a long-standing grievance within the replica community.
Powered by the reverse-engineered Super Clone Caliber 324, this movement mirrors the genuine layout, including the correct hand stack and balance wheel positioning. It operates at 28,800 vph with a free-sprung Gyromax-style balance, delivering approximately 36 hours of power reserve.
Machined from 316L stainless steel with a platinum-look finish, the case measures 40mm in diameter and weighs a verified 121.7g. The commemorative dial mimics the genuine lacquer thickness and features the signature 40th-anniversary embossing, with dial text annotations highlighted in a distinct dark tone.
