Jewlery evaluation

Good morning ladies and gentlemen I was wondering if I can get some help please? I bought a watch in 2016 and I have no idea what its worth I'm not quite sure what sort it is,
at this stage it's not for sale but it might be depending on what its worth.
It's a quatz watch
Completely silver with an interlocking band
A white face with quartz written at the bottom with what looks to be the letters 'CBD' at the top but this could also be a logo I have no idea
I have worn it for maybe 2 weeks
It's still got the original battery and nothing has been changed since I have owned it everything works completely fine
It is in pretty good condition
Any help is greatly appreciated have a nice day
