Description
NEWF Roger Dubuis Excalibur Skeleton Tourbillon RDDBEX0938
The NEWF execution provides a mechanically functioning flying tourbillon within a highly accurate 42mm skeletonized case architecture.
Powered by Custom RD509SQ Clone
This piece is driven by a customized manual-winding clone designated to replicate the RD509SQ. The caliber is built upon a reliable Chinese flying tourbillon base, heavily modified with decorative plates to emulate the genuine astral skeleton layout. The tourbillon cage itself is properly detailed, featuring the signature Celtic cross design. Regulation is managed directly via the tourbillon escapement, delivering an acceptable beat rate and stability for a high-complication replica.
±10–15 s/day. This is the standard operational tolerance for manual-wind clone tourbillon calibers, requiring consistent daily winding for optimal isochronism.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, flying tourbillon
- ✅ Winding Direction: Unidirectional manual wind
Technical Specifications
Maintains the genuine 42mm diameter with sharply defined triple lugs. The alternating brushed and polished facets on the complex case geometry are executed with high precision.
Features an unobstructed view of the geartrain and flying tourbillon. Accentuated structural elements match the genuine depth, with crisp printing on the outer flange.
The signature deep-notched Excalibur bezel is accurately milled, providing the correct light play and aggressive aesthetic inherent to the reference.
Custom molded to integrate seamlessly with the unique triple-lug design. Secured by a well-toleranced 18K rose gold plated folding clasp.
Why NEWF for This Reference?
Many collectors ask: “Why not standard automatic clone factories?”
Previous iterations of the Excalibur from lesser-known makers relied on standard open-heart automatic movements with faux bridges. NEWF integrates a true manual-winding flying tourbillon, drastically reducing case thickness to align with the genuine 42mm profile and eliminating the visual tell of a hidden rotor.
Full Disclosure: The 18K rose gold plating, while visually striking, will not possess the exact specific weight of solid gold, and the manual winding action of the clone caliber feels inherently heavier than the genuine RD509SQ.

Collector Q&A
Q: Is the tourbillon on this NEWF RDDBEX0938 fully functional?
A: Yes. Unlike lower-tier replicas that use an open-heart balance wheel to simulate a tourbillon, this NEWF edition utilizes a true mechanical flying tourbillon escapement that regulates the movement.
Q: How does the case thickness compare to the genuine Roger Dubuis?
A: By utilizing a manual-winding clone movement rather than an automatic base with a decorative plate, NEWF manages to keep the case profile extremely close to the genuine 42mm dimensions, avoiding the bulky proportions seen in older replicas.
Q: How durable is the 18K rose gold plating on the 316L steel case?
A: The factory uses an advanced plating process that is highly resistant to standard daily wear. However, it is still a surface treatment; deep scratches or heavy impacts will reveal the underlying 316L stainless steel.
Q: What is the primary operational quirk of this specific model?
A: The manual-winding tourbillon movement requires careful, deliberate winding. Because it is a delicate clone complication, users should stop winding immediately upon feeling resistance, and it yields a shorter power reserve (approximately 36 hours) compared to the genuine’s 70-hour capacity.
