Hi there
Pagol were a swiss firm as you say active until the 70's quartz revoloution.Their watches were aimed primarily at the asian and far east markets where they are known as the coconut tree brand,this is due to the logo of the palm tree usually seen on the dial and case back.Most of these watches that you see for sale will be from Singapore,Thailand etc.The movements used were eta types of varying spec but always good quality,the same movements were used by Titoni,Tressa etc.They are nice watches,they all had all steel cases and often very flamboyant dial with gem set batons etc.I like them !
Hope that helps!
