Description
BBSF Vacheron Constantin Overseas Tourbillon 6000V/110A-B544
A compelling execution of a high-complication sports watch, notable for its 12.0mm case profile and functional Maltese cross tourbillon.
Powered by Caliber 2160 Clone
The BBSF 6000V utilizes a custom-developed flying tourbillon movement engineered to replicate the visual impact of the Vacheron Constantin Caliber 2160. The highlight of this caliber is the rotating carriage at 6 o’clock, shaped like the brand’s signature Maltese cross. The bridge components feature hand-polished chamfering and perlage decoration, offering a high degree of visual fidelity when viewed through the sapphire caseback. Due to the inherent complexities of a rotating escapement, this caliber relies on manual winding to ensure consistent amplitude and reliable timekeeping across its power reserve.
±10–15 s/day. Tourbillon clone movements require careful regulation and are generally subject to wider positional variance than standard three-hand calibers. The rotating carriage actively compensates for gravity, but overall precision depends heavily on consistent mainspring tension.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: 6 o’clock functional flying tourbillon
- ✅ Winding Direction: Manual winding required for optimal torque
Technical Specifications
Machined to a verified 12.0mm thickness and weighing 184.8g, the case balances wrist presence with complex internal architecture.
Features a deep lacquer finish over a sunburst base, accented by super luminous hour markers and hands for high contrast.
Constructed with the iconic six-sided gear design, showcasing sharp transitions between the polished flanks and satin-brushed top surfaces.
Links mirror the half-Maltese cross motif, engineered with minimal endplay and secured by a robust double-folding deployment clasp.
Why BBSF for This Reference?
Many collectors ask: “Why not BBR or EUR Factory?”
While other factories have produced notable tourbillon clones, the BBSF execution of the 6000V achieves a highly impressive verified 12.0mm thickness. Housing a rotating carriage escapement in a case this thin is notoriously difficult for replica manufacturers, yet BBSF manages this while maintaining a substantial 184.8g weight, resulting in a highly balanced and authentic wrist feel.
Full Disclosure: The genuine Vacheron Constantin Caliber 2160 utilizes a peripheral winding rotor to keep the movement thin and fully visible. The BBSF clone movement uses a modified manual-wind architecture to accommodate the tourbillon within the 12.0mm case, meaning the caseback view and winding mechanics differ structurally from the genuine.

Collector Q&A
Q: Does the tourbillon on the BBSF 6000V actually function or is it an open heart?
A: It is a fully functional flying tourbillon. The escapement rotates continuously at the 6 o’clock position within the Maltese cross carriage, actively regulating the timekeeping of the movement.
Q: How accurate is the 12.0mm case thickness compared to the genuine model?
A: The genuine Vacheron Constantin 6000V measures 10.39mm thick. The BBSF model achieves a verified 12.0mm. While slightly thicker than retail, this is an impressive technical feat for a replica housing a complex rotating escapement.
Q: Is the blue dial color accurate to the genuine Overseas?
A: BBSF uses a translucent blue lacquer applied over a sunburst brushed base. It captures the dynamic light play characteristic of the Overseas line very well, though it can appear marginally darker in low-light environments compared to the genuine dial.
Q: What is the main structural difference in this clone movement?
A: The genuine Caliber 2160 utilizes a peripheral winding rotor to maintain a thin profile and offer an unobstructed view of the movement. The BBSF clone relies on a modified manual-wind architecture to fit the tourbillon within the 12.0mm case, meaning the rear bridge layout and winding mechanics deviate from the genuine counterpart.
