Description
ZF Factory Vacheron Constantin Overseas 4500V Coffee Edition
A structurally precise recreation defined by its verified 11.0mm thickness and functional quick-release strap integration.
Powered by Custom Clone Caliber 5100
Rather than attempting to clone the complex internal geometry of the genuine Caliber 5100 from the ground up, ZF utilizes the proven Miyota 9015 as a base movement. This strategic choice allows the factory to maintain the ultra-thin case profile while delivering superior mechanical reliability. The movement is heavily decorated with custom plates, Geneva stripes, and an intricately engraved 22K gold-style wind rose rotor to provide a convincing aesthetic through the sapphire exhibition caseback.
Regulated to ±10–15 seconds per day. The Miyota 9015 base offers excellent amplitude stability and high-beat (28,800 vph) consistency, ensuring the seconds hand sweeps smoothly.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, center seconds, and rapid-set date at 3 o’clock
- ✅ Winding Direction: Unidirectional (characteristic of the Miyota 9015 base)
Technical Specifications
Machined to an exact 41mm diameter and a verified 11.0mm thickness. The case exhibits precise alternating brushed and polished finishes, capturing the complex light play of the genuine sports watch.
Features a dynamic brown satin-brushed finish that shifts in direct light. The velvet-texture minute track and applied luminescent indices offer excellent depth and visual contrast.
The iconic six-sided bezel is highly polished, providing a sharp structural transition into the integrated case. The geometric precision here is a major focal point of the ZF build.
The bracelet links are meticulously finished with polished inner angles. The functional quick-switch system allows for tool-less removal, operating smoothly with minimal endplay.
Why ZF for This Reference?
Many collectors ask: “Why not MKS or 8F?”
ZF remains the definitive choice for the 4500V due to two primary factors: the verified 11.0mm case thickness and the superior engineering of the quick-switch strap system. Competing factories often utilize thicker movement architectures resulting in a bulkier case profile (often exceeding 11.5mm), or they fail to replicate the seamless functionality of the strap release mechanism.
Full Disclosure: Because the ZF utilizes a Miyota 9015 base, the unidirectional winding rotor can produce an audible spinning sound in quiet environments—a common trait of this caliber.

Collector Q&A
Q: Does the ZF quick-switch strap system accept genuine Vacheron Constantin straps?
A: While the ZF quick-switch mechanism functions identically to the genuine system, micro-tolerances in the lug attachments mean OEM straps may require slight modification to click securely into place without friction.
Q: How accurate is the ‘Coffee’ dial color compared to the genuine 4500V?
A: The ZF sunburst coffee dial captures the dynamic brown tones well under natural light, though it can appear marginally darker and less translucent in low-light conditions compared to the genuine Vacheron Constantin lacquer.
Q: Is the movement a true 1:1 clone of the Vacheron Caliber 5100?
A: No. It uses a highly reliable Miyota 9015 base movement that has been heavily decorated with custom bridges and a 22K gold-style wind rose rotor to mimic the visual architecture of the Caliber 5100, rather than cloning the internal gear train.
Q: What is the main drawback of this specific ZF release?
A: Because it utilizes a Miyota 9015 base to maintain the thin 11.0mm case profile, the unidirectional winding rotor can produce an audible spinning sound in quiet environments, a known quirk that differs from the silent operation of the genuine caliber.
