Revealing the soul of its mechanism through the transparency of its sapphire case, the new Vanguardskeleton sapphire showcases its movement to the fullest.

Innovation and expertise coupled with Haute Horlogerie traditions has enabled Franck Muller® to design this one-of-a-kind timepiece, achieving an unprecedented achievement. Manufacturing a sapphire watchcases of this kind requires a high degree of hand-finishing, high expertise and a unique savoir-faire. The case, bezel and back this timepiece are milled from a single block of sapphire. It takes two months to machine the case and then two more to accomplish the polishing.

The high-tech transparent tonneau watchcase is emphasized by the architectural design of the white PVD skeleton dial, hand-chamfered to perfection.

The perfectly integrated transparent strap attached to the glass case is totally invisible so that the skin of the wrist can be seen through it.

Taking a new direction with its minimalist style, the Vanguard skeleton sapphire offers a full visual access to its in-house manufactured movement.
