The word "Lifestyle" in the RM 72-01's designation is doing specific work. Richard Mille's earlier chronograph references — the RM 011 Felipe Massa, the RM 011 series in its various material configurations, the subsequent RM 11-03 — were conceived and positioned as extreme performance instruments, their design vocabulary derived from Formula 1 and their physical specifications calibrated to survive the conditions of professional motorsport. The RM 72-01, introduced in 2020, departs from this brief in a manner that its own name acknowledges directly: a watch for wearing, for daily use, for the collector whose primary relationship with the watch is not competitive timing but the possession of a Richard Mille chronograph whose dimensional profile accommodates the full range of wearing contexts that a high-achieving daily life actually involves. The case's 38.40 by 47.34-millimeter footprint — substantially more compact than the RM 011's 50 by 40 millimeters — is the formal expression of this revised positioning; at this scale, the RM 72-01 occupies the wrist with a presence that is substantial without being the architectural statement that the RM 011 family's dimensions require. The rose gold configuration is the most materially considered of the RM 72-01's material options, the warm precious metal producing a watch whose character is more formal and more explicitly jewellery-adjacent than the titanium and ceramic variants, while carrying the same CRMC1 caliber that makes the RM 72-01 the most significant Richard Mille reference from a movement history perspective.
The CRMC1 is the first movement manufactured entirely in-house by Richard Mille. This is the watch's most consequential attribute for the collector who understands Richard Mille's production history. Every Richard Mille chronograph caliber before it — the RMAC1 in the RM 011, the RMAC2, the RMAC3 in the RM 11-03 — was built on an established base caliber from an external movement supplier, with the flyback chronograph and complication modules supplied by specialist houses and the entire assembly then finished, regulated, and configured by Richard Mille. The CRMC1 changes this architecture at the foundational level: the movement was developed entirely within Richard Mille's own technical department, from the movement's basic going train through the complication architecture, with no external base caliber as its starting point. The significance of this shift is not merely commercial — the claim of "in-house" movement production is a prestige marker in the industry — but technical: the movement that results from a fully integrated development process can be optimized across all its interactions rather than adapted across the boundary between a base caliber designed for one purpose and a complication module designed for another. The CRMC1's patented flyback chronograph architecture is the direct result of this integrated development.
The flyback chronograph mechanism within the CRMC1 is built around a specific and patented approach to the problem of torque management in a flyback chronograph: the dual oscillating pinion system. In a conventional flyback chronograph — whether column wheel or cam wheel, whether external module or integrated — the chronograph's counter wheels (the central seconds hand, the 60-minute counter) are driven by the same train as the base movement's timekeeping function when the chronograph is engaged, the shared energy producing the risk that starting and stopping the chronograph affects the timekeeping train's regularity. Richard Mille's solution in the CRMC1 splits the torque generated for the chronograph across the counters through two oscillating pinions mounted on rockers, each pinion controlling a different counter function — the coupling and decoupling of the chronograph's seconds wheel from the display and from the minutes-and-hours connection managed independently by the two rockers rather than by a single engagement mechanism. The six-column wheel governs the start, stop, flyback, and reset functions in the sequence that a column wheel's pillar-and-lever architecture provides, its six columns — rather than the four or five of many contemporaries — optimizing the simultaneity of actions and the stability of the latched positions between operations. Richard Mille's own documentation describes the result as a chronograph that draws power directly from the barrel to supply all three counters, with the separation of the chronograph function from the base timekeeping train's operation ensuring that the chronograph's running does not impede the movement's precision. The movement operates at 28,800 vibrations per hour — 4 hertz — with 39 jewels and a power reserve of approximately 50 hours, plus or minus ten percent, from the automatic bidirectional winding rotor.
The baseplate and bridges are machined from grade-5 titanium — the same 90-percent-titanium, 6-percent-aluminum, 4-percent-vanadium aerospace alloy that the RMAC1 and RMAC3 movements use — then micro-blasted and subjected to a grey electroplasma treatment that produces the specific surface hardness and even, matte grey surface that the CRMC1's bridges present when viewed through the skeletonized dial. The electroplasma treatment, distinct from conventional PVD in its electrochemical rather than physical deposition mechanism, produces a surface layer that is bonded to the titanium rather than deposited on it, the adhesion producing a more wear-resistant surface than conventional physical vapor deposition. The CRMC1's bridge architecture — specific to this caliber and to the integrated development that produced it — is visible in its full configuration through both the dial-side sapphire crystal and the exhibition sapphire caseback, the bidirectional rotor's rotation visible through the back.
The skeletonized dial presents the movement's visual architecture with the specific layout that the CRMC1's design determines: the hours subdial at approximately one o'clock, the minutes subdial at approximately five o'clock, and the running seconds subdial at nine o'clock — three registers distributed asymmetrically across the movement's visible field rather than at the standard bicompax positions of three and nine or six and nine. The date display appears between four and five o'clock. The function indicator — Richard Mille's gearbox-inspired display of the crown's current operating position, showing W for winding, N for neutral, and H for hand-setting — eliminates the ambiguity of conventional crown positioning by providing a visible confirmation of which crown function is currently active. Luminescent material in the hands and indices provides low-light legibility across all five display positions. The flyback function is accessed through the pusher in the case flank, the single push returning the central chronograph hand to zero and immediately restarting it.
The rose gold case's finishing — the combination of polished surfaces and satin-brushed planes that characterizes Richard Mille's case architecture across precious metal configurations — presents the RM 72-01's tonneau shape in the material that most directly transforms the watch's design register from technical instrument to luxury object. Against the grade-5 titanium movement's matte grey bridges and baseplate, visible through both the dial and the caseback, the rose gold case's warm reflective surfaces create a material dialogue across the watch's thickness: the precious exterior and the aerospace-alloy interior occupying the same object in a relationship that the "Lifestyle" designation acknowledges without fully resolving — the watch is neither purely technical nor purely precious, but the specific hybrid that Richard Mille's design philosophy produces when the performance engineering standard is held constant and the case material is changed.
The RM 72-01's position within Richard Mille's production history — as the first fully in-house movement, in a case scale more accommodating than the RM 011 family's, in the rose gold material that positions it furthest from the purely technical register — makes it the reference through which the collector market will evaluate Richard Mille's ambition beyond the partnerships and external movement suppliers that defined its first two decades. Whether the CRMC1's dual oscillating pinion flyback represents a genuine mechanical advancement over the RMAC3's architecture, or a differently engineered solution of equivalent practical performance, is a technical judgment that watchmakers are better positioned than marketers to make. What the collector can assess directly is that the RM 72-01 in rose gold is the first Richard Mille chronograph in which every part of the mechanical argument — from the going train's baseplate to the flyback's column wheel — was developed within the same engineering environment, and that this integration has produced a movement whose architecture is specific to it rather than adapted from another maker's foundation.
