In the realm of integrated luxury sports watches, the Vacheron Constantin Overseas 4500V sits proudly alongside the Patek Philippe Nautilus and the Audemars Piguet Royal Oak as part of the "Holy Trinity." While factories spent the last decade perfecting the Nautilus and Royal Oak, the Overseas remained a notoriously difficult reference to clone. The reason? The dial.

The genuine VC 4500V features a dial crafted with multiple layers of translucent blue lacquer over a sunburst base, creating an almost liquid, bottomless depth that shifts drastically depending on the lighting. Furthermore, the bezel and bracelet links are designed to echo the Maltese cross, requiring incredibly precise, multi-angled polishing and brushing. In 2026, ZF (Z Factory) emerged as the undisputed leader in replicating this masterpiece.

The Blue Lacquer and Maltese Bezel

ZF's iteration of the blue dial is a staggering achievement. Older replicas from lesser factories used flat, metallic blue paint that looked lifeless indoors. ZF utilizes a multi-stage coating process that brilliantly captures the deep, aquatic blue of the genuine Vacheron. The applied white gold-plated hour markers and hands are flawlessly finished and filled with bright, even lume.

When reviewing your QC photos, your primary focus should be the bezel. The six "teeth" of the Maltese cross bezel must be perfectly symmetrical. Occasionally, minor factory batch variations result in a slightly misaligned bezel where the teeth do not sit perfectly centered between the lug lines. Ensure your agent provides top-down, straight-angle photos to verify this alignment.

The Miyota 9015 Base

To achieve the sleek 11mm case thickness of the genuine 4500V, ZF had to select a very slim base movement. Instead of building a highly unstable proprietary clone from the ground up, ZF made the practical choice to use the Miyota 9015. As detailed in our hyper clone movements overview, the 9015 is an absolute workhorse—reliable, cheap to service, and delightfully thin.

Through the sapphire caseback, you will see a heavily decorated movement. ZF applied custom plates to mimic the Vacheron Calibre 5100, capped off with a beautifully engraved golden rotor shaped like a wind rose compass. The only drawback of the 9015 is its unidirectional winding; the rotor can be slightly noisy when spinning freely. A simple drop of Moebius oil from a watchmaker will completely silence it.
