called “Bergter” this limited series, which consisted of 6 different type of models: little second, pointer date, regulateur, power reserve ( Auf und Ab ), chronograph, perpetual calendar.
Originally the watches was limited to 100 pieces of each models, except the perpetual calendar, which was limited to 25 pieces. After the succes of the first bunches of the Bergters Union raised the limitation number to 200 pieces per models, except of the perpetual calendar.
Common was the handwound movement, the caliber 30, which is the same base movement as the legendary 49 caliber of GO, only a less decorated and has fewer screwed chatons.
The Bergter was a huge success of the brand, today they are selling above retail, the collectors respect this series a lot!
I have had 4 Bergters, the handwound date, the regulateur and the power reserve ( two times ! ).
Yours,
Adam
