Swiss Night Reading Technology - Ball NM2038 Mode D'emploi

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) that gives the watch its excellent dark reading capability in any adverse

conditions. They provide superior night reading capability that is 100 times
brighter than the current tritium-based luminous paints.
require batteries nor to be recharged by an outside light source, or the use
of a press-button, and glow continuously for up to 25 years. You can read
off time from the watch quickly and safely in brightest daylight or deepest
night without adapting your eyes to the ambient light.

The H Swiss technology captures tritium safely in a very stable form,
as a pure gas sealed in a hollow body of mineral glass. Its exterior walls
are coated with a luminescent material, which gives off cold light when
activated by electrons emitted by the tritium. Light production is the same
as in a TV tube, when the electrons of the cathode ray beam hit the screen.
Please note that brightness of the H gas lights will gradually decline over
3
time, but can be restored by replacing with new dial.
