Few years ago I bought this old worn down watch and I actually paid a small amount money for it

Bracelet sucks, crown gone, hands fallen off , chrome plating wears off, the works
I must have been nuts , right ?
But when you look at the back , something odd.. it says Breitling , geneve , 8142 , 1968
inside the caseback more surprises , again Breitling Geneve and the bracelet marking seems OK as well
Ive never seen one before or since and I am really curious to know , whats the verdict here ? and how ashamed of myself should I be ?
