A luminous watchfor those unfamiliarhas hands and indexes coated with paint that stores lightallowing the time to be read in darkness. A nighttime saviour for adventurers and soldiers alikethese timepieces have a long and surprisingly hazardous history.
Luminous paint for watches can be broadly divided into two categories: phosphorescentwhich absorbs and accumulates light in bright places before gradually releasing itand self-luminouswhich emits light on its own. In the pastluminous paints made with radioactive materials such as radium and tritium were commonbut they have all but disappeared due to their harmful effects on the human body. Todaythe only self-luminous paints still in use are special types that employ tritium gas safely sealed in micro-capsules.
In recent yearsluminous paints have become almost exclusively phosphorescent. The global standard is Luminova (N Luminous)developed by the Japanese company Nemoto in 1941and its successor Super-Luminovawhich applies the same technology. Within this category“Grade X1” and “Grade X2” variants offer enhanced brightness and durabilityalongside an expanding palette of luminous coloursincluding yellowgreenblueand orange.
Innovative designs have also emerged – some illuminate the entire dialwhile others feature a “glowing exterior” where luminous paint is mixed into the case itself. These models are being re-evaluated not only as practical tools for visibility in darkness but also as striking examples of and function combined.
Without further adohere are 13 timepieces that look even better when night falls.
