Description
MK Factory Vacheron Constantin Overseas Dual Time 7920V White Dial
The MKF iteration provides a robust mechanical execution of the complex 5110DT caliber while maintaining strong case geometry.
Powered by Clone 5110DT Movement
The heart of this 7920V replica is the modified Clone 5110DT automatic movement. To achieve the correct dial layout, MKF utilizes a reliable base caliber fitted with a custom module that drives the pointer date, the secondary time zone hand, and the AM/PM indicator. While visually decorated to mimic the genuine Vacheron Constantin Geneva Seal finishing, its core architecture prioritizes functional stability over exact 1:1 part interchangeability.
Standard testing for this heavily modified clone caliber typically yields an accuracy of ±10–15 seconds per day, depending on the resting position and active engagement of the dual-time module.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Dual Time (GMT), Pointer Date, AM/PM Day/Night Indicator
- ✅ Winding Direction: Bidirectional automatic winding
Technical Specifications
The case measures 41mm across with a verified thickness of 13.3mm. The signature Maltese cross bezel features alternating polished surfaces and brushed vertical satin sides.
A clean white backdrop supports 18k white gold plated hour markers. The sub-dials exhibit correct concentric texturing, though the lacquer depth is marginally shallower than genuine.
Machined from solid 316L steel, the bezel’s six-sided gear profile is crisply defined, avoiding the overly soft edges seen on lower-tier replicas.
Features stylized Maltese cross links with exceptional articulation. The deployant clasp offers secure closure, though the quick-release mechanism feels slightly stiffer than genuine.
Why MKF for This Reference?
Many collectors ask: “Why not 8F?”
While older 8F versions struggled with the reliability of the dual-time module and overall dial proportions, MKF has refined the 5110DT clone architecture. The MKF edition presents a more stable pointer date mechanism and superior application of the blue luminous material on the hands and markers.
Full Disclosure: To house the complication module, the case thickness is 13.3mm, which is 0.5mm thicker than the genuine 12.8mm specification.

Collector Q&A
Q: How does the dual-time function operate on this MKF clone?
A: The crown independently adjusts the local hour hand in one-hour increments, while the home time (arrow hand) and AM/PM indicator remain synchronized to the primary movement gearing, accurately mimicking the genuine caliber’s functionality.
Q: Is the case thickness identical to the genuine 7920V?
A: No. The genuine Vacheron Constantin 7920V measures 12.8mm in thickness. This MKF edition is verified at 13.3mm to accommodate the modified clone 5110DT movement module.
Q: Are the bracelet links interchangeable with genuine Vacheron straps?
A: While the quick-release mechanism visually replicates the genuine system, the lug tolerances and connection points differ slightly. Genuine rubber or leather straps will likely require modification to fit the MKF case securely.
Q: What is the most common quirk with this specific MKF clone movement?
A: Due to the added module layers, the pointer date at 6 o’clock can occasionally exhibit slight visual misalignment between the 28th and 31st of the month, and the rotor produces more audible bearing noise compared to a standard three-hand caliber.
