JARDENA, Switzerland
German owned
It seems that there was some cooperation once between JARDENA and Citizen Germany. I found this watch in a watch chain called Christ in Switzerland. Citizen Germany obviously had shares of Christ too. Later the discount drug-store Douglas took over Citizen. I do not know whether Citizen Germany is still a shareholder of the German Brand Jardena
Please note that I have corrected the caliber to ETA (Valjoux) 7750. It was previously wrong 7751 and this still shows in the file names which I did not change
