TECHNICAL SPECIFICATIONS OF THE RICHARD MILLE TOURBILLON RM 019
CALIBER RM019: manual winding tourbillon movement with hours, minutes and power reserve.
Dimensions: length 45 mm x 38.30 mm x 12.25 mm
MAIN FEATURES
(MANY OF WHICH ARE MAJOR TECHNICAL INNOVATIONS)
POWER RESERVE
48 hours. This is indicated utilizing a newly designed differential power reserve system, with a red line on a moving disc placed between 10 and 11 o’clock.
BLACK ONYX BASEPLATE
Onyx is a variety of cryptocrystalline quartz chalcedony composed of silicium dioxide, (SiO2). The variety with rectilinear black and white parallel stripes is part of the agate family; whereas the fully black type is known as Black Onyx. A gemstone able to deflect and channel harmful energy towards the Earth, it provides stability. For this reason, Black Onyx is considered a stone of protection against negative thoughts, as well being the stone of equilibrium and inspiration.
VARIABLE INERTIA, FREE SPRUNG BALANCE
The free-sprung balance gives better reliability in the event of shocks, movement assembly and disassembly, and also guarantees better chronometric results over an extended period of time.
BARREL PAWL WITH PROGRESSIVE RECOIL
This device permits an appreciable winding gain (circa 20 %), especially during the start of winding. It also aids in the even distribution of the mainspring’s internal tension.
