Selling this 1970s Certina Argonaut 220 from my personal watch collection. Case back is stamped with the ref. 5201-220 and serial number 7361542. The Swiss movement is mechanical wind up and the second hand has a nice sweep motion. Case is brushed steel with some nicks and scratches but i think it adds to the character. The cross hair dial and hands are all original. The hands lume shows signs of patina and a little deteriorated. ...My favorite feature is listening to the inner workings of this piece ... its mesmerizing. Fashioned with a brand new black genuine leather 19mm 2-piece strap. Great watch for man or woman in my opinion. All sales are final on this vintage collectible. This Certina 220 is in perfect working condition. I will wrap with care for new owner. Please understand that shipping vintage time pieces such as this can incur shock and may need a quick service upon arrival. All sales are final.
