Description
YSF Factory Richard Mille RM 027 Tourbillon
A technically proficient manual tourbillon clone housed in a specialized graphite-coated titanium chassis.
Powered by RM 27 Tourbillon Clone Calibre
The mechanical core of this YSF edition is a bespoke manual-winding flying tourbillon, engineered to mimic the suspended architecture of the genuine RM 27 calibre. The movement features deeply skeletonized baseplates and bridges, finished in a matte black tone to contrast with the silver-toned gear train and black balance wheel. The tourbillon cage rotates smoothly at 21,600 vibrations per hour, offering a mesmerizing visual focal point at the 6 o’clock position while maintaining stable chronometric performance.
±10–15 seconds per day. Regulated prior to dispatch, this manual tourbillon offers reliable timekeeping typical of high-grade clone escapements.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: 60-second flying tourbillon
- ✅ Winding Direction: Unidirectional manual wind
Technical Specifications
Measuring 43mm by 50mm and 15mm thick, the case utilizes a specialized hydrogen-free graphite coating over titanium to increase hardness by 40% and achieve a matte, high-tech visual texture.
Deeply open-worked display showcasing the manual movement, featuring painted dot hour markers and a #006039 deep green accent profile on the inner flange.
Secured by functional Richard Mille-style titanium spline screws, providing correct tension across the three-part tonneau case construction.
A highly pliable black rubber strap featuring a honeycomb pattern for breathability, secured by a titanium tang buckle with correct milling depths.
Why YSF Factory for This Reference?
Many collectors ask: “Why not EUR or BBR Factory?”
While EUR produces excellent tourbillon movements, YSF’s specific application of the hydrogen-free graphite film over Grade 5 titanium provides a distinct advantage for the RM 027. This surface treatment far better replicates the matte, porous look of the genuine carbon nanotube composite than standard PVD or DLC applications, while simultaneously reducing case weight.
Full Disclosure: The genuine RM 027 is famous for its 19-gram total weight. While the YSF titanium construction is impressively light for a mechanical replica, it remains significantly heavier than the genuine carbon nanotube piece—a physical limitation of current replica material science.

Collector Q&A
Q: Does the tourbillon function like the genuine RM 027?
A: Yes, this YSF edition features a fully functional, rotating manual-winding flying tourbillon, rather than a fixed open-heart escapement.
Q: How much does the YSF RM 027 weigh compared to the genuine?
A: The genuine RM 027 weighs an astonishing 19 grams due to its carbon nanotube construction. The YSF uses Grade 5 titanium with a graphite coating; while noticeably lighter than standard steel replicas, it cannot replicate the extreme ultralight weight of the genuine reference.
Q: What is the power reserve on this tourbillon movement?
A: The manual-winding RM 27 tourbillon clone provides approximately 36 hours of power reserve on a full wind.
Q: Are the spline screws on the bezel functional?
A: Yes, the YSF factory uses functional, star-shaped spline screws constructed from titanium, accurately securing the three-part case assembly with correct tension, just as on the genuine model.
