Introduction

Richard Mille and Ferrari: making hearts beat faster

Sporting mechanisms that are as elegant as they are immediately recognisable. An identical obsession with excellence, precision, reliability and innovation. In 2021, Ferrari and Richard Mille, driven by their shared quest for perfection, joined forces to create a long-term partnership. Richard Mille celebrates this budding relationship with the creation of an exceptional ultra-flat timepiece, the RM UP-01 Ferrari.

At just 1.75 millimetres thick, the RM UP-01 Ferrari constitutes a triumph of technical prowess and exemplifies a new approach to watch mechanics in which technicity more than ever dictates aesthetics.

Ferrari, a sight to see

The collaboration between Richard Mille and Ferrari teams, most visibly expressed in the choice of materials and execution of the watch, also precisely lent the project the competitive spirit so essential in the most exhilarating adventures.

The RM UP-01 Ferrari is an allusive piece to Ferrari’s values, developing sporting mechanisms that are as elegant as they are immediately recognisable. Their models make no concessions and frequently contradict current trends to create new aesthetical codes. The RM UP-01 Ferrari bears witness to this partnership of the best know-how these two iconic brands have to offer in the combination of their ideas, understanding, respective developments and shared values.

RM UP-01

A UNIQUE OBJECTIVE

Even in the realm of extreme flatness, we were determined to make a watch that met the same validation requirements as all our other models. In this quest for absolute flatness, we had to offer a watch that, far from being a ‘concept watch’, was up to the task of following a wearer’s daily life.

Performance as an accelerator of style

Working collaboratively alongside the Ferrari team, the RM UP-01 is a model resulting from many year’s work, dozens of prototypes and more than 6,000 hours of development and laboratory testing.

Meeting the challenge of an ultra-flat watch precluded a traditional movement with superimposed gears and hands. Richard Mille therefore opted to distribute what could not be stacked over a broader surface area by creating a perfect symbiosis between the movement and case, each ensuring the necessary rigidity of the other.

We were determined to retain a traditional architecture in which the movement is assembled within the case, rather than a construction in which the caseback doubles as a baseplate, in order to ensure under any circumstances total shock resistance.

BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM

The baseplate and bridges of the RM UP-01 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.

The skeletonised baseplate was subjected to separate and extensive validation tests to ensure it met rigorous optimal strength requirements. The calibre RMUP-01 can withstand accelerations of over 5,000 g’s.

FUNCTION SELECTOR

Integrated into the bezel, the function selector located between 10 and 11 o’clock allows one to select the winding (W) or the hand-setting (H) function with a simple rotation of the crown.

Setting the time or winding the barrel is then possible by turning the second crown located between 7 and 8 o’clock.

Surrounding the crowns, two black ceramic inserts protect the bezel from friction and ensure water resistance.

PATENTED ULTRAFLAT ESCAPEMENT WITH VARIABLE-INERTIA BALANCE WHEEL IN TITANIUM

In the course of developing the RM UP-01 Ultraflat, engineers from Audemars Piguet Le Locle and Richard Mille developed a new type of escapement with a balance wheel in titanium that drastically reduces the calibre’s thickness whilst providing the same security as a conventional Swiss anchor escapement.

The parts that add the most height in a traditional escapement are the dart (aka guard pin) and the safety roller. Both serve to bank the lever in case of shock. The new patented, ultraflat escapement eliminates both parts and resituates the banking function directly on the anchor fork. To do so, the fork itself was elongated and its horns modified. As a result, the dart-free anchor is significantly reduced in height.

The escapement transfers energy to a variable-inertia balance wheel, thus ensuring great stability during assembly, disassembly and exposure to shock or strong vibrations. The movement thus offers optimal chronometric precision for an extended period. The regulator index is eliminated and a more accurate and repeatable calibration is possible thanks to 6 adjustable weights located directly on the balance.

FAST-ROTATING BARREL (6 hours per revolution instead of 7.5 hours)

This type of barrel provides the following advantages:

• The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance.

• An excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.

Fighting for the last hundredths

With the RM UP-01 Ferrari, Richard Mille is proud to present an ultra-flat watch just 1.75 millimetres thick. This mind-blowing technical feat owes as much to approaching watch mechanics with fresh eyes as it does to reframing design methods in ways that make the spectacular available for use in everyday situations.

For such a project, it was necessary to set aside all the knowledge we had amassed over years of practice, and every conceivable standard of watchmaking. This is precisely what we did throughout our collaboration with the laboratories of Audemars Piguet Le Locle. Shaving off those last hundredths of a millimetre of depth was an extremely demanding and lengthy process.

CASE

The design and execution of the entire watch bears witness to a comprehensive conceptual approach to the movement and the case, which are developed in complete harmony. It represents the first appearance of this new and highly identifiable form within the Richard Mille collection. Its uncompromising slimness perfectly symbolises the Richard Mille philosophy of letting technique dictate aesthetics, once again transforming the tonneau shape and adapting it to new circumstances.

The RM UP-01’s case has the same characteristics and exhibits the same sleek lines and attention to minute detail, as the large number of manufacturing operations required for its bezel and its monobloc caseband and caseback attest.

Grade 5 Titanium

The entire case is machined from grade 5 titanium, a material offering great lightness combined with levels of resistance proven in the laboratory through a rigorous battery of tests. The monobloc construction also optimises rigidity while guaranteeing water resistance to 1 atm (10 m).

Due to the low profile of the RM UP-01, all the components are machined at the Richard Mille movement department to meet the extremely demanding machining tolerance of a single micron.

The caseback and bezel are satin-finished, with polished bevels. The iconic prancing horse and all the references present on the case are laser-engraved. This unique ultra-thin case is assembled using 13 grade 5 titanium spline screws and abrasion-resistant washers in 316L stainless steel.

Other features

WINDING-BARREL TEETH AND THIRD-WHEEL PINION WITH CENTRAL INVOLUTE PROFILE

The central involute profile of the winding-barrel teeth and pinion provides an optimal pressure angle of 20°. This promotes effective rotary motion and compensates for possible variations in the engagement of the going train, thus ensuring excellent torque transmission with a distinct improvement in performance.
