Description
ZF Richard Mille RM 035 “Baby Nadal”
A masterclass in skeletonized movement replication and lightweight tonneau case manufacturing.
Powered by RMUL2 Manual Clone
The beating heart of this replica is a heavily modified manual-winding caliber designed to replicate the visual layout of the authentic RMUL2. ZF has invested significantly in the bridge architecture, ensuring the skeletonized baseplate features the correct PVD-treated sandblasted finish. While it lacks the true free-sprung variable inertia balance of the genuine article, the gear train and barrel placement provide an excellent visual illusion of depth, maintaining the signature suspended aesthetic.
Regulated prior to assembly, this manual caliber typically yields an accuracy of ±10–15 seconds per day, well within the acceptable tolerances for a heavily modified skeletonized clone.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, and central sweeping seconds
- ✅ Winding Direction: Manual winding only via the crown
Technical Specifications
Constructed from a high-density alloy/composite to mimic the genuine Alumagnesium feel. The tripartite case is secured by accurately torqued spline screws.
Features a matte black PVD finish with subtle deep blue accents on the inner flange. Hands are properly filled with luminous compound for low-light visibility.
Precisely machined to match the exact curvature of the wrist. The matte surface finishing resists fingerprints and minor abrasions.
Integrates seamlessly into the lugless case design, providing excellent pliability and comfort. Secured by a titanium-finished spring deployant clasp.
Why ZF for This Reference?
Many collectors ask: “Why not KVF or BBR?”
While KVF produces highly durable RM clones, their case profiles historically suffer from excessive thickness, ruining the streamlined tonneau aesthetic. BBR excels in actual tourbillon movements, but for the standard skeletonized RMUL2, ZF provides superior bridge finishing, correctly chamfered edges, and a much more accurate overall case dimension.
Full Disclosure: The manual winding action on the ZF clone feels slightly stiffer than the buttery-smooth genuine caliber, and the balance wheel is a visual replication rather than a true free-sprung system.

Collector Q&A
Q: Does the ZF RM 035 use an actual tourbillon movement?
A: No. While replica titles often include ‘Tourbillon’ as a broad search keyword, the genuine RM 035 and this ZF replica both feature a skeletonized manual-winding RMUL2 movement. It utilizes a standard balance wheel mechanism, not a rotating tourbillon cage.
Q: How does the weight of the ZF compare to the genuine RM 035?
A: The genuine RM 035 uses an ultra-light Alumagnesium alloy, weighing under 40 grams. The ZF replica utilizes a lightweight composite/alloy that brings the weight to approximately 65 grams. While slightly heavier than genuine, it remains exceptionally light and comfortable compared to standard steel replicas.
Q: Are the spline screws on the bezel functional or purely decorative?
A: The spline screws on the ZF model are fully functional. They structurally secure the tripartite tonneau case together, mirroring the genuine Richard Mille assembly method. Special multi-point screwdrivers are required for servicing or opening the case.
Q: What is the main visual flaw of the ZF RMUL2 movement?
A: The primary tell is the balance wheel assembly. The genuine caliber features a free-sprung balance with variable inertia, whereas the ZF clone uses a standard regulated balance wheel decorated to mimic the authentic architecture. Additionally, the gear train depth is slightly shallower than the genuine counterpart.
