Radium Dial Watches (historical)

overall review score: 3
score is between 0 and 5
Radium-dial watches are historical timepieces that feature dials painted with radium-based luminous paint, allowing them to glow in the dark. These watches were primarily produced during the early to mid-20th century, especially from the 1910s through the 1950s, and were popular among military personnel, pilots, and watch enthusiasts for their visibility in low-light conditions. The use of radium, a radioactive element, provided an exceptional level of luminescence but later was discovered to pose significant health risks to those handling and manufacturing these watches.
