Combining H. Moser & Cie.’s watchmaking prowess with the craft of gem-setting, the Streamliner Tourbillon Rainbow in red gold dazzles with its sapphire gemstones. Invisibly set into the bezel, each sapphire is of a different color, displaying a full spectrum of tones around the dial. In a striking play of contrasts, the flying tourbillon rotates above the dial made ofVantablack®, an innovative coating used in astrophysics and taken from the aeronautical industry.
