It will be easy if you will post watch picture as well. Cheers.

 

That's the one! Thanks for that! No idea why it wasn't coming up when I searched! Watch pics attached. Is it too good to be true at £500!?

 

Yes as for me its too good....

Something is fishy, the price is way too good to be true. Unless the watch is not in working condition, but even then..

 

Well it's up for £800 but he seems desperate to sell. How can you tell by cards and watch together if it's fake?

 

try to post some better pics....
