Moon Phase Starry Sky

Reference: DB25sJWS1

Million shades of blue inlaid with diamonds and white gold stars. The De Bethune blue titanium dial captures the infinitely complex beauty of the sky and breathes life into it. 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.
