1) The model number on the caseback does not relate to the model this watch should be. It reads 'GN-4W-S', which when I googled, came up with a very old Citizen 21 Jewels Automatic watch...
No the eBay member is based in London... a Mr Abid Hussain, according to Paypal.
Yeah it is looking that way but thought maybe a few people owned this watch and could confirm?
Worth just contacting Citizen
They can give you advice to check if it is fake and perhaps check serial number etc
You also have proof then when it comes to claiming from paypal
I believe the GN-4W-S is a servicing code for citizen...it's not the watch model number
