Good Evening, i have recently found this Kienzle watch from my late Great grand father, rumor is that he got it for a birthday somewhere in the 70's. There is unfortunately no more background information. I have tried to find some information on my own but failed because i cannot find ANY serial number or name whatsoever (Strange isn't it?). Movement only says "17 Seventeen Jewels". Caseback only says "Kienzle Germany" and "Stainless steel". Watchface says "KIENZLE", "17 Jewels", Made in Germany". I was hoping someone here had any shred of info or even resources where to look for more info. Thanks a lot! P.S.: I promise better pictures in the future. This was kind of a spontaneous cellphone act of carnage.
