Traser

Traser is the Swiss company behind the original tritium illuminated watches. Trigalight® are independent of a battery or any other source of outside energy, never need recharging or servicing and do not require a push of a button. Trigalight® are small glass vials hermetically sealed, coated on the inside with phosphorescent material and filled with minute amount of tritium gas. Electrons emitted from the gas excite the material to give off a permanent light.
