On the basis of cutting-edge research on new materials combined with ancestral technics, the natural oxidation of titanium is an exclusive process that requires exceptional skills developed by the Manufacture. A palladium and flame-blued steel spherical moon completes this vibrant picture, intensifying the hypnotic impression of depth and infinity.
