Developed in collaboration with Sylvester Stallone, the new RM 25-01 Adventure tourbillon chronograph| attests a desire on the part of Richard Mille and the artist to conquer the most thoroughly hostile of natural environments. Hero of the novel First Blood by David Morell, John Rambo has embodied our idea of the adventurer for over thirty years. First portrayed on film in the guise of Sylvester Stallone in 1982, this character of a man tormented by a war without mercy had a major impact on the actor’s career, revealing Sly as the man of Hollywood action films. With its hitherto unheard-of functionalities that go to the very heart of the watch, the RM 25-01 could easily be imagined on John Rambo’s wrist. Truly a horological UFO, this timepiece is, as Sylvester Stallone says, “Ready for action”.

Despite our sedentary modern lifestyle, humans retain from our nomadic past a thirst for adventure and discovery. As new technologies make it possible to situate oneself to the nearest centimetre anywhere on the globe, today’s adventurers seek to challenge their capacity to survive under perilous conditions. The goal of the technical approach adopted by the RM 25-01 was to provide a tool that would allow these brave souls to get around safely, wherever they might be. Stallone has always had a distinct preference for imposing wristwatches. Many noted the RM 032 on a red strap that he wore throughout The Expendables 3, which he also directed. It was thus incumbent on the RM 25-01 to adopt the round shape of the former, perfect for accurate reading of the time and suitable for housing a compass, a crucial piece of equipment no adventurer should be without, which Stallone specially requested. In terms of movement, the calibre RM25-01 tourbillon is Richard Mille’s signature technicity at its best.

Its baseplate and bridges, machined out of grade 5 titanium, effectively support a mechanism that combines a tourbillon complication and the complexity of a new ‘competition’ chronograph movement. It took the brand’s engineers several months of work to optimise the calibre. In the end, they successfully reduced its weight while increasing its precision and long-term chronometric reliability. The overall reduction in inertia goes hand in hand with a 50 per cent lower energy consumption. The 70-hour power-reserve, visible using the coupling and function indicators, drives an unusual 24-hour display, essential for distinguishing am and pm should the viewer be deprived of sunlight. The round case showcases a combination of titanium and Carbon TPT®, the indestructible composite whose damascene surface has become something of a brand signature, and which significantly reduces the overall weight of the watch.

Water resistant to 100 metres, the RM 25-01 comes with two interchangeable bezels. The first is a compass in grade 5 titanium with a DLC coating that has both a fixed and a rotating bezel. Its bayonet mount makes it quick and easy to fix on the case. The Carbon TPT® cover has a mirrored back and a slot at 12 o’clock to increase precision of sightings with the compass needle. Its sapphire crystals have a multilayer anti-reflective treatment, as well as an antimagnetic coating to prevent any mutual interference of the movement and compass. A spirit level located at 4 o’clock makes it possible to check that the watch is perfectly horizontal for better readings. Detached from the watch, the compass may be affixed to a plate made of Carbon TPT®. Ideal for orientating, this configuration provides—among other things—lines indicating the direction to take when following a course on a map.

The compass bezel may be switched out by the wearer for a bidirectional bezel in Carbon TPT® and titanium, with a 24-hour scale, a 360° graduated disc, and indications for the cardinal directions. No calculations are required—all that’s needed is to face the sun with the hour hand and turn the bezel so the local time is indicated on its 24-hour scale—the wearer can then identify North, South, East and West in either hemisphere. At 2 o’clock, a hermetic compartment in grade 5 titanium can hold water purification tablets that make a litre of any water safe to drink in 30 to 120 minutes, depending on the level of pollution.

In keeping with the spirit of adventure that emanates from this limited edition of 20 pieces, designed with ‘Sly’ Stallone, a sculptural strap in natural rubber sporting a camouflage motif and a strong pin-buckle in grade 5 titanium keep the ergonomic curves of this imposing case securely on the wrist as only the Richard Mille brand knows how.

The RM 031 is a timepiece that brings together a grand watchmaking tradition with cutting-edge concepts. The concept is classical: its objective is to provide the world’s most regular mechanical calibre. It achieves this goal with a variation of just 20 seconds per month, an unprecedented feat.

This calibre, offering hours, minutes, seconds oversize date, flyback chronograph, UTC and countdown functions—to say nothing of the function selector and a power-reserve indicator—required the design of over 1,000 all-new pieces. To this day, it remains the most complicated watch ever produced by Richard Mille.

This tourbillon calibre has a 70-hour power reserve, a function selector and a g-sensor placed at the centre of the sapphire crystal. This last can be set with a simple twist to the g-force you wish to calculate (acceleration, deceleration, turn).

Caliber RM25-01: Manual winding tourbillon movement with 24-hour display, minutes and chronograph function, power reserve, torque and function indicators.

Diameter: 50.85 mm x 23.65 mm.

Power reserve
Circa 72 hours (numerical zone on the left of the barrel) .

Baseplate and bridges made of grade 5 titanium
Baseplate and 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.
The skeletonised baseplate and bridges have been subjected to intensive and complete validation tests to optimise their resistance capacities.

Competition chronograph movement
Richard Mille engineers spent several months of work and research reducing the weight and optimising the calibre, especially the precision of time calculation over the long term. This has given rise to many innovations, such as the design and manufacturing of several titanium parts, like the levers, which reduce inertia and thus lower energy consumption by 50%. This made possible to significant alleviate friction on the axis and eliminate jumps and twitches of the chronograph hand during start or stop of the timer.
Operation: the chronograph function is stopped and started via the pusher located on the lower left at 8 o’clock. The hands are reset by pressing another pusher, located on the upper left at 10 o’clock.

Torque indicator
This indicator supplies information about tension in the mainspring, thus permitting an optimisation of the movement’s chronometric functioning. Below 53 dNmm, the spring is considered too slack, while above 65 dNmm, excessive spring tension can adversely affect the mechanism’s operation, or indeed endanger it (these indications appear on a numerical zone near 2 o’clock).

Function indicator
Similar to a car’s gearbox, the function indicator allows one to see the winding, neutral and hand-setting positions as the crown is pulled out.
The current position is indicated via a hand at 4 o’clock displaying the following functions: W (Winding) – N (Neutral) – H (Hand Setting).

Free-sprung balance with variable inertia
The free-sprung balance offers increased reliability in the event of shocks and movement assembly or disassembly, thus achieving better chronometric results over time. The index has been eliminated, allowing more precise and repeatable adjustment using 4 setting screws.

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.

Barrel pawl with progressive recoil
This device permits an appreciable winding gain (circa 20%), especially during the start of winding. It also aids in ensuring even distribution of the mainspring’s internal tension.

Winding barrel teeth and third-wheel pinion with central involute profile
The wheel with a central developing profile and a pressure angle of 20° promotes rolling movement more effectively by compensating differences between centres, thus ensuring excellent torque transmission with a distinct improvement in performance.

Modular time-setting mechanism fitted against the caseback
Provides the following advantages for longevity and maintenance:

• Since the component is mounted outside of the movement, the time-setting assembly can be changed without affecting the integrity of the baseplate in the event of a possible defect or during maintenance,
  
• The mounting and dismantling of this module from the back will not require removal of the hands or dial.

Spline screws in grade 5 titanium for the bridges
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

Case in carbon TPT® and titanium
Carbon TPT® is an exclusive material with a unique damascene appearance. Its remarkable surface displays extremely regular striations, as Carbon TPT® is composed of many layers of parallel filaments obtained by dividing carbon fibres. These layers, with a maximum thickness of 30 microns, are impregnated with resin, then woven on a special machine that modifies the direction of the weft by 45° between layers. Heated to 120°C at a pressure of 6 bars, the Carbon TPT® is then ready to be processed on CNC machines in Richard Mille’s parts factory.
The case of the RM 25-01 is water resistant to 100 metres, ensured by two Nitrile O-ring seals. The case is assembled with spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.

Spline screws in grade 5 titanium for the case
This permits better control of the torque applied to screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.

Compass
The compass consists of a fixed bezel and a rotating bezel, both crafted in DLC-treated grade 5 titanium, with sapphire glass. It attaches to the case with a bayonet mount. Its cover is made of Carbon TPT®, and includes a mirror with an opening at 12 o’clock that permits greater precision when orientating with the compass needle. The spirit level contained within a titanium bubble makes it possible to hold the watch exactly horizontal to improve accuracy when sighting with the compass needle.
Once removed, the compass can be affixed to Carbon TPT® baseplate. Ideal for orientation, this arrangement provides a number of indications, including engraved lines showing the direction to head in when following a course with a map.

Bidirectional daytime bezel
The titanium bezel can be exchanged for a ‘daytime’ bezel should the owner so desire.
This second bezel, in Carbon TPT® and grade 5 titanium, possesses marks for the four cardinal directions in addition to a 360° graduated disk and a 24-hour scale.
This mechanism relies on two pieces of information: knowledge of local time, and the position of the sun in the sky. The indications on the bezel of the RM 25-01 make it possible to orientate not only in the Northern, but also in the Southern hemisphere, without additional calculations, simply by choosing the appropriate scale.

Water resistant receptacle
This module, in grade 5 titanium, is hermetically sealed to stash water purification tablets that can make any source of water safe to drink.

Torque-limiting crown
This added security system prevents accidental overwinding of the watch, which can cause damage to the winding stem or place extreme pressure on the barrel spring.
