Well, this is the right place to post it.

What is the condition of the watch? It's nice that you have a box, but its the condition of the watch that matters. If the watch has any flaws (cracks, dents, scratches, LCD segment errors, stuck buttons...) it will sell for much less. Also, for these old Seiko computer watches, the watch's communication with the keyboard is crucial. Does it work well with the keyboard?

In my opinion, a fully working, mint condition Seiko UC-3000 should easily sell for $200+. (Having said that, I wouldn't pay that much for it myself.)

Virtually nobody will pay good money without first seeing pictures though. Give us pictures!
