Bring on the night

This is our Chromalight display. Unveiled in 2008, it offers optimal and long-lasting legibility in the darkest of surroundings thanks to a luminescent substance developed by Rolex and patented. White under the light of day, it glows blue in darkness and makes it possible to read the time in all lighting conditions.

Composed of aluminum, strontium, dysprosium and europium, it has the ability to store ambient light’s energy only to better release it, gradually, whenever it may wane. First obtained in powder form, it is then heated to a very high temperature and mixed with a resin, before being applied manually to the hands and indexes. Its characteristic blue hue is a most reliable ally to repel the reach of darkness. A most precious glow in even the darkest of nights.
