Addition Timer in ABS case Lumen 1/5 sec.

For use in industry and, especially, in laboratories, Hanhart offers two watches in its precision mechanics range with luminous dials.
Once the special dial has been “charged” with light (takes approx. 1 hr.), the face will glow in the dark for approx. 3-4 hours so it is clearly readable. This requires no additional energy or radiating materials. This useful property is achieved by using an innovative plastic material containing lightstoring pigments.
The practical ABS case of the “Lumen” has additional dust and water protection.
In a special production process, the glass and the glass fixing ring are moulded together and then firmly screwed to the case.
Of course, these watches are also popular with athletes, as they always have been.
