Overview
The Smiley composition in a transparent case
The photograph shows the RM 88’s dial architecture — the gold Smiley, Olivier Kuhn’s micro-sculptures, the red gold flange, the cloud fixed to the tourbillon and the W/H function indicator at 3 o’clock — inside a transparent case, on a white strap with a yellow-collared crown.
Richard Mille’s published material for the RM 88 describes one case configuration: ATZ white ceramic with a 5N red gold caseband, in an edition of 50 pieces. A sapphire-cased RM 88 appears neither in that material nor in the launch coverage. The case is therefore recorded as photographed, and the edition and year left open.
The mechanical content is the RM 88’s: the CRMT7, a skeletonised automatic tourbillon with hours, minutes and a function indicator, built on two baseplates so that the ornamentation sits clear of the movement.
Key details
Design and engineering
- Calibre CRMT7Skeletonised automatic winding tourbillon movement with hours, minutes and a function indicator, running at 28,800 vph (4 Hz) with around 50 hours (± 10%) of power reserve. It measures 32.10 × 29.00 mm by 4.80 mm thick on 23 jewels, and Richard Mille records three years of development.
- Two baseplatesOne technical baseplate carries the movement; a second auxiliary plate mounted onto it secures the ornamentation and presents the objects on an inclined plane for volumetric effect, while keeping the assembly shock-resistant. The Smiley sits higher than the rest, on the motion-work bridge, which takes the form and colours of a rainbow.
- Gold micro-sculpturesA flower, the sun, a pineapple, a cactus, a flamingo, a rainbow and a cocktail glass, engraved in gold by Olivier Kuhn, each weighing under a gram and each required to survive shock. The spines of the cactus are individually polished to remove the green PVD coating beneath, the cocktail glass is built from four solid gold parts, and the flower is mirror-polished with rhodium-plated petals.
- Figurative secondsThe small-seconds hand alternates between rain and fine weather each minute, gliding over an ARCAP cloud fixed to the tourbillon before hiding beneath a small cloud in microblasted and satin-finished white gold.
- Function indicatorA hand at 3 o’clock shows the winding and hand-setting positions as the crown is pulled out, in the manner of a car’s gearbox.
- Sun-shaped rotor3N yellow gold, shaped as a sun, on the OneWay® winding system with ceramic ball bearings, winding the fast-rotating barrel. It is hand-decorated, the bevelling included.
- Free-sprung balance with variable inertiaFour small adjustable weights on the balance, with the regulator index eliminated.
