Swiss watchmaker Richard Mille has introduced four new versions of its RM 07-02 timepiece, each housed in different colored sapphire crystal cases. The collection consists of pink, lilac, and two variations of green sapphire, with production limited to seven pieces per color.
Each case demands over 1,000 hours of machining to achieve its final form. The latest addition to the color palette is lilac, which posed unique challenges during development. The creation of this specific hue required extensive testing, as sapphire becomes more susceptible to structural changes during the heating and growth processes needed to achieve the color.
The dials feature geometric patterns set with a combination of precious and ornamental stones. Diamonds share space with blue and yellow sapphires, while orange spessartite, white agate, and opal provide contrast. Various green stones - including tsavorite, chrysoprase, and malachite - complete the stone selection. The placement of these gems follows a precise arrangement to maximize light reflection.
At the technical core of these timepieces is the CRMA5 movement, developed in-house by Richard Mille. This skeletonized automatic caliber shows hours and minutes and operates with a 50-hour power reserve. Depending on the version, the movement's baseplate and bridges are crafted from either red or white gold.
The collection marks a continuation of Richard Mille's work with sapphire crystal cases, a material chosen for both its durability and transparency. Each of the four variants - pink sapphire, lilac sapphire, green sapphire, and an alternative green sapphire version - displays the internal mechanics through its translucent case.
Pricing details have not been announced for these new additions to the RM 07-02 line.
