Richard Mille Product Description


The fountain pen is a symbolic luxury object designed to appeal to the daily or occasional user, the simply curious, the connoisseur and the collector alike. Locked for centuries in an endless cycle of popular or stylistic reinterpretations, it has rediscovered its true worth with Richard Mille. We have revolutionised this quintessential writing instrument, transforming it into a pure product of watchmaking by virtue of a mechanical movement as complex as any RM calibre.

The last word in cutting-edge technology and innovation, with a strong artistic angle and optimally ergonomic design, the mechanical fountain pen epitomises the brand’s entire philosophy. The pen is equipped with a genuine, manufactured calibre, thus fitting perfectly with the Swiss Jura watchmaker’s development and production strategy. It offers those in the know a product that captures the essence of Richard Mille, in the same way as the mechanical titanium cufflinks did. Developed by the brand’s movement creators, the pen took almost four years to research and develop before emerging as an exceptional, highly technological, one-of-a-kind product.

Baseplate And Bridges Made Of Grade 5 Titanium

Based upon the same technology and attention to mechanical detail as Richard Mille’s timepieces, the fountain pen uses a selfwinding pen calibre to extend the pen’s 18K white gold nib.

The components of this mechanism are in grade 5 titanium with electroplasma treatment for the calibre’s baseplate and PVD coating for the bridges. This provides the unique, extremely small calibre’s skeletonised extending mechanism with great rigidity and precise surface flatness for perfect functioning.


Exactly as you find in every horological creation, the mechanism of the RMS05 requires an escapement in order to work perfectly. In this case, a recoil type escapement, often found in clock movements was chosen. This ensures the regularity and speed of the pen’s nib as it automatically extends.

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.
