Aerospace Super Black Watch Face

Technology developed at Harvard University and used before by many prominent aerospace compainess only for a satellite-borne blackbody calibration systems as the darkest man-made substance at its time. Applying it as a super-black coating to watch dials was a big step for mankind, brave step for us. Its unique physical and optical properties have resulted in produing the best readable watch dial and could be described as the closest thing to a black hole. It absorbs virtually all incident light, making it ideally suited to addressing a host of light-suppression and light-management problems, such as under water or under extreme sun.

Luxury meets science

  • Best luminescence, strongest glow

    To achieve the best readability experience provided in contrast on the dial, we teamed up with a Swiss company RC Tritec, a world leader in lume technology for 80 years, to source their luminescence technology for our timely watches.
