So I have this watch. My grandmother found itlike 40 years ago on the ground. I can not find any serial numbers or identifiers. I even popped off the back, it just takes out the whole mechanism with the face in one piece. the back simply says "K&O 14 kt solid gold," It is white gold with 6 jewels in the body, and them an embellished band with stretch on the back with 4 gems on either side on the band itself ( 8 all together on band) i am assuming it is from before the 50's. It has a very art deco feel to it. I looked all over for one even close and couldn't find one. I tried the Gruen webpage for some assistance and without a serial number or style number there is no help there. I was wondering if anyone has seen one like this or could point me in the direction of someone who has? I am looking to see if it is worth anything, as my grandmother has fallen on hard times. Thanks in advance.
