RELENTLESS TECHNICAL INNOVATION

Produced in collaboration with the famed Formula 1 constructor, the new Richard Mille calibre is a technical masterpiece offering off-the-chart mechanical performance. First expression of the 10 year collaboration between the two teams. Click to discover the dedicated site : RM 50-03 McLaren F1 SIHH 2017

Main characteristics

« The RM 50-03 represents a new approach to the challenges of lightness underlying our watchmaking philosophy. »
Richard Mille

The RM 50-03 McLaren F1 weighs less than 40 grams – including the new “comfort” strap – which makes it the lightest mechanical chronograph ever made.
This landmark has been achieved through the use of cutting-edge technical materials.
The design not only incorporates Titanium and Carbon TPT™, but also introduces an entirely new material into the world of watchmaking:
Graph TPT™, more commonly known as Graphene.

A chronographic perfection brought to life: it combines a tourbillon escapement with a split seconds function.
In order to perform without fail, the combination of these two complications within a single mechanism demands perfect transfers of energy.
A technical masterpiece offering exceptional mechanical performance.

Produced in a numbered limited edition of 75 pieces available only at Richard Mille boutiques.

01
NEW SPLIT-SECONDS SYSTEM
Studies focused on the work of the split-seconds clamp and the six-column wheel that controls the various rockers of the mechanism have perfected its simultaneity of movement -essential to absolute accuracy- function lock, and the stability of its settings over time.

FUNCTION INDICATOR In a manner similar to a car’s gearbox, the function indicator allows one to identify the Winding, Neutral and Hand setting positions as the crown is pulled out.

CALIBER RM50-03 Manual winding tourbillon movement. Ultralight tourbillon calibre in titanium and TPT carbon.

TORQUE INDICATOR Indicates the tension of the mainspring and makes it possible to optimise the winding of the watch. Under 53 dNmm, the spring is too slack. At over 65 dNmm, however, the excessive tension could affect the operation of the mechanism, or even damage it.

THREE-PART CASE

Highly resistant. Extremely light, preserving perfect ergonomics and a unique, striking appearance. The bezel and caseback feature Graph TPT, a TPT Carbon whose physical properties have been considerably improved by the injection of Graphene, a revolutionary nanomaterial six times lighter than steel but 200 times more resistant.

TORQUE-LIMITING CROWN

This added security system prevents accidental overwinding of the watch, which could result in damage such as snapping the winding stem or putting too much pressure on the barrel spring.

7 GRAM MECHANISM

The secret to its feather weight lies in the use of grade 5 titanium and TPT Carbon for the baseplate and bridges and in the extreme skeletonisation of its components. The transverse cage crafted of TPT Carbon and inspired by the wishbone suspension structure of a McLaren-Honda Formula 1 car, supports the entire calibre.

STRAP

Thanks to Richard Mille's partnership with BIWI SA, a Swiss company specialised in very-high-precision moulding of vulcanised elastomers, Graphene was injected into the rubber strap of the RM 50-03 in order to improve its rubber-like behaviour and thus its resistance to wear.
