Trying to get the value of my watch

Hey guys!
I'd like to ask for a bit of help from you guys trying to get value on the watch which I inherited from my Grandfather.
The watch is in like 95% condition it's almost new worn only a few times.
It's a Fortis watch with this number on their back: 625.22.141 this is the serial number I guess.
I found a few on the internet but I have no idea if those prices are right. I'm not into luxury watches that much so I'd like to sell it and never sold any luxury watches before no idea where to start.
Thanks for helping!

 

Go to a jewelry shop and ask an expert. I'd also consider keeping the watch, pretty cool to pass something like that down.

 

Chances are the ones you've seen online are correct prices. I saw it on a watch shop for $1,500.

You can always go ahead and send me the watch (no return address needed)

 

Yeah thats what I found aswell.
Thanks for checking it.

 

The good thing I like about expensive watches is that they never lose there price
