          Case

          Richard Mille has turned to new colored ceramics for these RM 07-01 bezels: Blush pink TZP ceramic for the RM 07-01 Pastel Pink, lavender pink TZP ceramic for the RM 07-01 Pastel Lavender and powder blue TZP ceramic for the RM 07-01 Pastel Blue.

          Tetragonal Zirconia Polycrystal is a biocompatible ceramic constituted of over 95% zirconia (ZrO2). Its properties include remarkable corrosion resistance, a hardness providing scratch resistance (1,400 Vickers) and toughness superior to that of sapphire, associated with a desirably low density of around 6 g/cm3. The submicron grain size furthermore permits excellent surface finish for a stunning matt effect.

          A long and difficult machining and grinding process using diamond tools is necessary to create the complex forms of the bezels. The casebands are made of microblasted white gold with hand-polished pillars.

          The three-part case is water resistant to 50 metres ensured by 2 Nitrile O-ring seals. The case is assembled with 12 grade 5 titanium spline screws and abrasion resistant washers in 316L stainless steel.
