This series was originated from the German alarm clock factory Jerger. When Jerger decided to stop the production of the well known alarm clocks, Ronald Johansen from Græsted took over the tools and the rights to produce the instrument-housing. Ronald Johansen was the manufacturer of the Fyrkat instruments and the take-over of the Jerger series gave him the possibility to supply an economy series to the clock business.
In 2003 Ronald Johansen decided to stop his business and today the series is produced by Delite in Måløv.
Since 2014 the series has been a collectable.
