Bia Watches Luminous Dials


Bia's luminous dials are powered by Visible247

10 MINUTES EXPOSURE TO DAYLIGHT = 10 HOURS OF ILLUMINATION

Bia Watches feature Visible247, a revolutionary new illumination technology that uses miniature light receptive crystals molded into the watch dials, resulting in the highest performing photo luminescent injection molded polymers ever created.
Expose to any type of light source for just 10 minutes, and it will glow in the dark for at least 10 hours - a much more durable glow than has been possible until now. Our lume technology is available in a variety of color choices that glow in a multitude of colors.
