ZF Factory Edition — Integrated Steel Bracelet
The ZF iteration of the Vacheron Constantin Overseas 4500V has established itself as the horological benchmark for this reference, primarily due to its accurate case geometry. By achieving a verified 11.0mm thickness, it perfectly mimics the slender profile of the genuine piece while successfully integrating a functional quick-switch strap mechanism. This engineering allows collectors to alternate between steel, rubber, and leather without tools, a critical feature for the Overseas line.
Powering the timepiece is a heavily modified Miyota 9015, operating at 28,800 vph (4Hz) to ensure a smooth sweeping seconds hand. ZF has restructured the movement architecture with custom bridges and a signature 22K gold-style wind rose rotor to emulate the visual footprint of the Vacheron Caliber 5100. As with all non-Dandong clone calibers in this tier, the movement provides a stable power reserve of approximately 36 hours.
The 41mm case is machined from 316L stainless steel, featuring the model’s signature alternating brushed and polished surfaces. The dial presents a deep coffee brown sunburst finish, complemented by a velvet-texture minute track and applied indices. The iconic six-sided Maltese cross bezel transitions seamlessly into the integrated lugs, maintaining strict dimensional fidelity to the 152g total weight.
