With this timepiece, Richard Mille invites you to stare into the very soul of the watch. The transparent casing conveys every nuance and every detail, making it impossible to covertly disguise any undesirable traits or errors in the watch.
The extraordinary timepiece builds on the earlier model in the RM 56 series, with design and material upgrades that greatly reveal the artistry behind every tick and oscillation of the movement. The unusual design of this watch is the perfect demonstration of Richard Mille's dedication to precision and innovation.
Richard Mille RM 56-01 History
The journey to the RM 56-01 began in January 2012 when Richard Mille unveiled the RM 056 sapphire at the SiHH trade show. The Sapphire Split-second chronograph watch was limited to just 5 pieces. Thanks to its exquisitely finished casing, the groundbreaking timepiece sent ripples through the watchmaking watch, which was made entirely of sapphire crystal. The RM 056 was a revolutionary timepiece with a design remarkable enough to elevate the Richard Mille brand to an unrivaled level of innovation mastery.
A year after achieving this incredible technical feat, Richard Mille continued with its culture of challenging the very limits of its own creation. In 2013, the RM 56-01 was unveiled as a limited 5-piece model, just like its predecessor.
Officially dubbed the RM 56-01 Sapphire Crystal, this timepiece consolidated Richard Mille’s status as a master of skeletonization with even more sapphire crystal components compared to the RM 056. In addition to building directly on the remarkable feat achieved with the earlier model, the watch borrowed inspiration from the older timepiece RM 018 Homage to Boucheron. This timepiece, released in 2008, also had a sapphire crystal baseplate.
The RM 56-01 essentially combines the transparent casing of the RM 056 with the extraordinary transparent movement of the RM 018. This was achieved by swapping out the titanium baseplate of the older model with a Sapphire one.
The RM 56-01 might seem like a technical downgrade because it eliminated the split-second chronograph function present in its predecessor. Still, the timepiece is an upgrade in its design, achieving a level of skeletonization never before seen in the industry - an upgrade that is arguably just as difficult to pull off as any complication.
RM 56-01 Features
It goes without saying that the RM 56-01 is an incredible feat of horological engineering. The watch makes a strong visual statement, thanks to its sapphire structure, which took the watchmaker years to pull off. At the same time, Richard Mille has ensured that the timepiece still meets the standards of strength and comfort set for all its models, achieving aesthetic brilliance without compromising quality.
Transparent Case Design
An exquisitely crafted sapphire crystal casing characterizes the Richard Mille RM 56 01. This unique case has been meticulously fashioned by Richard Mille to demonstrate remarkable transparency and a sense of technical mastery. Thanks to this unique case design, this watch's internal components appear visible through a crystal-clear exterior.
The watch still retains the three-part case design inspired by the RM 056. This design has all the components of the timepiece: front bezel, back bezel, and case band machined entirely from a solid block of sapphire crystal.
According to Richard Mille, it took over 40 days of 24/7 machining operations to produce just one case, using a special CNC machine purchased just for this watch. All the sapphire crystal components of this timepiece have been crafted by world-renowned sapphire crystal specialists.
Beyond its aesthetic brilliance, this case was designed to sit perfectly on the wrist, ensuring absolute comfort for the wearer. The chase is held together by 24 grade 5 titanium spline screws and has transparent nitrol O-ring seals that make it water-resistant to a depth of up to 30 meters.
Sapphire Crystal Movement
With the older RM 056, the use of sapphire crystal material stopped with the casing as its movement was made largely from titanium components. Richard Mille pushed even further with the RM 56-01 by creating a new Calibre RM56-01 movement with a baseplate, allowing as much light to penetrate it as possible.
The tourbillon Sapphire manual-winding movement appears suspended within the sapphire crystal case, providing a stunning view of the intricate inner workings of the timepiece. But the watchmaker proceeded further beyond baseplate. Other components of this watch, such as the central bridge and third wheel, are also crafted from sapphire crystal.
This unique design takes nothing from the technical excellence of the movement. The manually wound tourbillon movement has hours and minutes functionality, as well as indicators for the function selection, torque, and power reserve.
Captivating Dial
The dial of the Richard Mille RM 56 01 is a near-invisible canvas designed to express the watchmaker's art remarkably. You’ll understand why Richard Mille decided to eliminate the chronograph function when you see how uncluttered the dial appears despite its near-colorless theme.
The dial of this watch provides an enchanting visual experience, displaying the hours and minutes, a power reserve indicator at the 11 o’clock mark, a torque indicator at 2 o’clock, and an indicator to show the function selected for the crown at the 4 o’clock mark. The hour and minute hands have also been skeletonized, with white tips that promote legibility against the colorless background.
The rest of the dial is a raw view of the internal components of the movement, a horological equivalent of displaying the vital organs of a person’s torso. But in this case, it isn’t a gruesome sight. Instead, it’s a captivating view, displaying the complex micromechanics that drives such a masterpiece.
Stability and Performance
Despite using unusual materials, the RM 56-01 is not inferior to more conventional Richard Mille watches. The sapphire crystal and titanium combination keeps the acth stable and ensures that it continues to perform impeccably regardless of the condition.
The RM 56-01 is immune to temperature changes that may affect the functionality of other timepieces. It is also less prone to wear and tear over time. This makes it a reliable companion for a wide range of use cases.
