Junghans early quartz (cal 667.20)

Late 70s quartz watch by Junghans with the second generation Junghans quartz movement: the 667 (version .20). I'd say '76-'78 period (should be printed inside but could not find it so far).

 

Not a Max Bill and not a Astro / Astra Quartz but still decent, fresh, large (!) and a work horse. Some love for early quartzes ;)
