5.1 Swiss Night Reading Technology
How to read time from watches in dark
environments has been a topic of much research
in the watch industry. Applying luminous paints
to dial and hands - activated first by radium, then
by tritium - has been standard practice since
the First World War but did not really satisfy
the manufacturers. After a quarter-century in
research and development work, BALL Watch Company is proud to present
an innovative Swiss laser technology that is considered the best alternative
available today. It is the self-powered micro gas tube known as H
the watch its excellent dark reading capability in any adverse conditions.
They provide superior night reading capability that is much brighter than
the current tritium-based luminous paints. H

press-button, and glow continuously for decade. You can read off the time
from the watch quickly and safely in brightest daylight or deepest night
without adapting to the ambient light.
