Modern luminous materials work by absorbing light and gradually releasing that stored energy in darkness.

As a result, the glow naturally becomes less intense over time after the watch is removed from a light source.

This gradual reduction in brightness is a normal characteristic of all photoluminescent lume and should not be considered a defect.

To maximize lume performance, expose the watch to a strong light source before entering a dark environment.

The rate at which lume fades may vary depending on the model, the luminous material used, and the amount of lume applied to individual components.
