Hi, I have a 6159-7010 that has been in one of my drawers for over 30
years. It's not running, but the stem works and moves the hands fine.
The crystal has some scratches on it but you can still read the face
clearly. The back and cowl are nice, only very minor scratches that
you can't see, and the face looks to be perfect. It was never used too
much, most of the small scratches on it came from it being in a drawer
and not being properly stored in a box or case. It has no wrist band,
it had a black rubber model on it at on time. The dial was one of the
one's made that dose not have the  "M" on the face under the "600".
So, my question is this to the group, what might this watch be worth?
Should I try and have it serviced, or try to sell it as a project or
for parts as is. Please let me know your thoughts. Thanks much.
