Flying Tourbillon Sapphire Limited Edition

Solid Sapphire Crystal Case Engineering & Three Aquatic Color Iterations

The technical construction of the RM 75-01 Sapphire stands as a profound achievement in avant-garde lapidary artistry, with the entire tripartite housing—upper bezel, central caseband, and rear caseback—milled directly from solid blocks of synthetic sapphire crystal ($Al_2O_3$). Boasting a diamond-like scratch resistance rated at 2,000 Vickers, this crystal shell is completely clear due to its molecular framework and offers a unique tactile smoothness on the skin. Shaping a case of this immaculate 32.90 x 46.75mm dimension demands over 1,000 hours of specialized multi-axis CNC machining and polishing, requiring 430 hours for preforming the components and 350 hours of meticulous diamond-slurry polishing to achieve perfect optical transparency.

The collection is strictly limited to 15 pieces worldwide and reflects aquatic inspiration through three spectacular iterations:

1. The Clear Sapphire Model: Evokes sunlit waves, beautifully paired with a distinctive sea-green strap.
2. The Sapphire Pink Model: Incorporates a lilac pink sapphire caseback, reminiscent of twilight over calm, serene waters.
3. The Sapphire Blue Model: Incorporates a deep sapphire blue caseback, echoing the rich mysteries of the ocean floor.

Calibre RM75-01 – A Masterclass in Gothic Architecture & Suspended Flying Organs

At the beating heart of this pristine crystal sanctuary lies the high-performance manual-winding movement Calibre RM75-01, presenting an ultra-lightweight yet robust architecture where light and space intertwine. Visible through the sapphire crystals, the Skeletonised Dial layout exhibits an aerial mechanical theater punctuated by a Flying Tourbillon at 6 o’clock and a fast-rotating Flying Barrel (completing a rotation every 5.2 hours). By entirely eliminating the traditional upper bridges for these regulating and power organs, the movement creates a dramatic illusion of absolute weightlessness. The main structural baseplate is crafted from microblasted Grade 5 Titanium treated with a majestic 5N gold PVD coating, supporting rhodium-treated wheels and a dark bridge system that emphasizes depth and dimensionality.

The Pure Convergence of Ribbed Vault Geometry and Luminous Motion

The visual execution of the RM 74-02 edition redefines the relationship between structural shadow and radiant luxury light. Drawing inspiration from the architectural grandeur of ribbed vaults and Gothic symmetry, the monumental upper flange crafted from warm 18K 5N Red Gold rests elegantly upon hand-polished titanium pillars, serving as the technical keystone connecting the movement to the sapphire shell. The design layout features sweeping mechanical arcs accented with vibrant SuperLuminova elements that create a kinetic, luminous interplay in low-light environments. Sealed by dual Nitrile O-ring gaskets to secure a 30-meter water resistance and tightened by 24 titanium spline screws, this ultra-exclusive limited milestone stands as a premier investment asset globally.
