Overview

Red gold bezels over a titanium caseband

The RM 11-03 was introduced in 2016 as the replacement for the RM 011, which had been in the collection since 2007. Richard Mille’s stated aim was to give the new calibre a three-dimensional quality and bring its complexity visually forward. The tripartite tonneau case was reworked at the same time, its lines modernised without, in the brand’s words, denaturing the watch — the smooth flanks of the RM 011 giving way to raised pillars along the sides.

This execution combines 18K red gold for the front and back bezels with a grade 5 titanium caseband, the two materials sitting either side of the tonneau in the tripartite construction. The crown is grade 5 titanium, its form taken from competition wheel rims and tyre treads; the ribbed pushers recall pedal grooves and are capped in NTPT carbon.

The calibre carries a flyback chronograph with a countdown function and an annual calendar. The oversize date sits in a horizontal aperture below 12 o’clock and the month between 4 and 5 o’clock, the calendar adjusting automatically for months of 30 and 31 days.

Key details

Design and engineering

• Calibre RMAC3Skeletonised automatic winding movement with hours, minutes, seconds, flyback chronograph, 60-minute countdown timer at 9 o’clock, 12-hour totaliser, oversize date, month indicator and variable-geometry rotor. The movement measures 30.25 × 28.45 mm with a thickness of 9.00 mm and runs on 68 jewels at 28,800 vph (4 Hz).
• Double barrelTwo barrels mounted side by side, which Richard Mille specifies for stable coupling, providing circa 55 hours (± 10%) of power reserve. Actual reserve depends on how much the chronograph is used.
• Baseplate and bridgesGrade 5 titanium — 90% titanium, 6% aluminium, 4% vanadium — for rigidity and for the performance of the gear trains. The upper bridge is satin-brushed grade 5 titanium, contrasting with the PVD-coated titanium of the movement beneath; a satin-brushed PVD-treated lower bridge frames the double barrel on the caseback side.
• Variable-geometry rotorGrade 5 titanium, satin-brushed and PVD-treated, mounted on ceramic ball bearings, its form drawn from Formula 1 aerodynamic appendages. Two microblasted and chamfered wings in 18K white gold set the rotor’s inertia across six positions, matching winding to the wearer’s activity level.
• Free-sprung balance with variable inertiaGlucydur®, four arms, moment of inertia 4.8 mg·cm², angle of lift 53°, with an AK3 balance spring and Incabloc 908.22.211.100 shock protection. At 4 Hz it is specified as shock-resistant and more precisely tunable than an indexed balance.
• Three-position winding stemW for winding, D for date, H for hand setting.
• Annual calendarAutomatic adjustment for months of 30 and 31 days. The oversize date sits in a red-outlined horizontal aperture below 12 o’clock, the month display between 4 and 5 o’clock.
• Tripartite caseReworked from the RM 011, with chamfering and buffing carried out entirely by hand and the case held together by 20 grade 5 titanium spline screws.
