Richard Mille Product Description


We were intent on achieving extreme lightness on the RM 21-01 and we succeeded in constructing it on a titanium honeycomb structure. The objective was to juxtapose and laser-weld each tiny cell. This achievement on such a microscopic scale is a major technical tour-de-force.

Manual winding tourbillon movement with hours, minutes, function selector, power-reserve and torque indicators.

Limited edition of 50 pieces


Around 70 hours (± 10%).

Baseplate In Honeycombed Orthorhombic Haynes®214® With Carbon Tpt® Core

HAYNES® 214® is a nickel-chromium-aluminum-iron alloy, designed to provide the optimum in high-temperature oxidation resistance for a wrought austenitic material, while at the same time allowing conventional forming and joining. Intended principally for use at temperatures of 955°C and above, 214® alloy exhibits resistance to oxidation that far exceeds that of virtually all conventional heat-resistant wrought alloys at these temperatures.
Combined with a Carbon TPT® core, the honeycombed geometrical pattern of HAYNES® 214® offers unparalleled stiffness, a low thermal expansion coefficient and exceptional torsion resistance.

The orthorhombic baseplate is given a blue PVD treatment to highlight its original construction

Free-sprung Balance With Variable Inertia

This type of balance wheel guarantees greater reliability in the event of shocks and during movement assembly or disassembly, and also guarantees better chronometric results over time. The regulator index is eliminated, and a more accurate and repeatable calibration is possible thanks to 4 small adjustable screws located directly on the balance.

Bridges Made Of Grade 5 Titanium

Bridges are crafted of grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly. The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automotive industries. They are coated with a 5N gold PVD treatment.

Product Reviews

I couldn’t be more happy with my purchase with WATCHXNYC. Watch looked great and my AD said it was a great buy.
Watch arrived next morning after my wire cleared. It’s crazy I fell asleep and woke to the UPS guy delivering my watch. It was literally faster than amazon.
I was skeptical with buying an expensive Rolex online, but I took the plunge and I am so happy I did. The watch came in great condition, and Kevin was soo helpful with everything. I will be back!!


Are these watches real?

Yes. Every product we sell is authenticated using a multi-point inspection. We buy our own watches too! Just to keep you confident, we also offer a 100% refund guarantee for any authenticity issues.

What condition are your watches in?

Unworn is what most of our inventory is currently on condition. We do sell pre-owned watches for a discount, so that will also be communicated when you get into contact with us.

When will I get my watch?

We offer free overnight shipping and orders are processed same day. So often our customers receive their watch next day, or day after on more rare occasions. Exact delivery times will vary based on carrier and availability.

Can I see the watch before I buy?

It depends. We have multiple inventory locations, but no physical showroom. Depending on availability, and purchase, we could schedule you to see the watch before you purchase. However, it does require a deposit.

Are you a new business?

No. We are an executive team of 3 that have been working on 47th st in NYC (Diamond District) for close to 20 years now. Recently, we wanted to expand worldwide, so we opened WATCHXNYC – an online showroom brand to showcase our inventory and sourcing abilities. Rest assured, we know watches well.
