Description
NEWF Roger Dubuis Excalibur Skeleton Tourbillon RDDBEX0838
NEWF balances structural rigidity with delicate skeletonization, offering a reliable manual-wind flying tourbillon at an exact, verified 98.2g.
Powered by Clone RD512SQ
The clone RD512SQ caliber is the mechanical centerpiece of this reference. It features a fully operational flying tourbillon carriage that rotates completely every sixty seconds, serving as the actual escapement rather than a mere visual module. The skeletonized mainplate and star-shaped bridges are heavily machined to expose the gear train, requiring precise regulation to maintain beat stability. Hand-winding is achieved via the crown, engaging the visible mainspring barrel located at the upper right quadrant of the dial.
±10–15 s/day. This is the standard operating tolerance for Chinese manual-wind flying tourbillon calibers, prioritizing the complex rotation of the cage over chronometer-level precision.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: 60-second flying tourbillon, hours, minutes
- ✅ Winding Direction: Unidirectional manual wind via crown
Technical Specifications
42mm diameter with deeply skeletonized lugs. The use of a lightweight alloy brings the total mass to a highly accurate 98.2g, ensuring excellent wrist ergonomics.
Features the signature star-shaped bridge layout. Text annotations feature a dark green accent tone unique to this specific factory batch, diverging slightly from the standard monochromatic genuine.
The deeply notched Excalibur bezel features alternating brushed and polished surfaces, machined with sharp, distinct transitions between the flutes.
Custom-fitted rubber strap designed to sit flush against the triple-lug architecture, secured by a lightweight folding deployant clasp.
Why NEWF for This Reference?
Many collectors ask: “Why not BBR Factory?”
While BBR pioneered the replica Excalibur tourbillon, their cases often weigh significantly more than the genuine due to the use of denser steel alloys. NEWF’s strategic use of lightweight materials brings the total mass to a verified 98.2g, drastically improving wearability and much closer mimicking the genuine titanium feel on the wrist.
Full Disclosure: The manual winding feedback is noticeably grittier than the buttery smooth genuine RD512SQ, and the skeletonized bridge chamfering lacks true microscopic Geneva Seal anglage.

Collector Q&A
Q: Is the tourbillon at 7 o’clock fully functional or just an exposed balance wheel?
A: It is a true, fully functional flying tourbillon that rotates 360 degrees every 60 seconds. It actively functions as the escapement for the clone RD512SQ movement, rather than being a superficial visual module.
Q: How does the 98.2g weight compare to the genuine RDDBEX0838?
A: The genuine titanium model weighs approximately 90-95 grams depending on the strap. The NEWF factory’s verified 98.2g profile is exceptionally close, avoiding the heavy, unbalanced feel of standard steel replicas produced by other factories.
Q: Can I swap the strap with OEM Roger Dubuis quick-release straps?
A: While the lug width matches the 42mm genuine case, replica lug hole tolerances often vary by fractions of a millimeter. OEM straps may require slight modification to the spring bar channels to fit securely against the triple-lug architecture.
Q: What is the biggest visual tell on the NEWF RD512SQ clone movement?
A: The primary tell lies in the anglage (chamfering) on the skeletonized star bridge. The genuine movement features flawless, hand-polished microscopic bevels that reflect light evenly, whereas the NEWF bridge edges are machine-finished and appear slightly sharper and less refined under a loupe.
