Anker 15 rubis help

Hello
Can someone give me details about this watch ? I have recived this watch from my relatives and dont know much about it and i woud want to know how much is it worth and a bit o history
Thank you

It's an unusual watch --a key wind, key set wristwatch of relatively low quality. But it's not by IWC and this discussion forum really only discusses IWC watches.

thank you
