Superluminova: The essential luminescent material in haute horlogerie

In the continuous search for solutions for displaying the time in low-light conditions, haute horlogerie has incorporated innovative materials. Among them, Superluminova stands out as a significant advance, allowing the time to be seen even in the dark.

What is the Superluminova?

Superluminova is a substance composed of alkaline earth aluminate, with the remarkable ability to absorb light, both solar and artificial, and emit it in the dark. The duration of its brilliance depends on the intensity and duration of exposure to light.

Superluminova History

To understand the origin of the Superluminova, we must go back to 1902, when Marie and Pierre Curie discovered radium. Panerai, in 1910, was the first prestigious watchmaker to use radium and zinc sulphide to create luminous watches. Despite its popularity, radium was replaced in the 1960s due to its toxicity.

During the late 1950s, tritium and promethium were introduced as less harmful alternatives. However, it was not until 1998 that Luminova replaced tritium, becoming the preferred luminous material in watchmaking. Despite having been discovered in the 1960s, Superluminova gained prominence in the watch industry in the 2000s, surpassing Luminova in functionality.

With the growing interest in Superluminova, companies specialising in its manufacture emerged, such as LumiNova Switzerland, which launched Swiss Super-LumiNova® in 2007.
