Well for a brand new one with AD discount, I'd expect to be paying around £1700-1750.
For a 5 year old one with no papers, I'd say around £1000.
For a couple of year old one fully boxed with all warranty cards etc, probably around £1200-£1300.
Do not buy one with no papers, there are plenty more about
Generally people do not "lose" papers as they leave them in the watch box
for a start it could be fake
it could be stolen
it could have outstanding import taxes to pay
you will have problems reselling it
I'm not syaing it is always a no go but you need some serious money off and be 100% of its history
does it still have the serial number on it ?
The Omega "papers" are actually a credit card so would be hard to fake
If you trust the seler then that is a start
It has serial number so prob ok there
This leaves the tax situation, if it started life as an EU watch then no problem but without papers how can you tell that
If not at any point you pass through a UK customs post ( airport etc ) you could get stung for the import taxes, happened to a mate recently
The above is not relevant if it was/has any of following
Original EU papers or receipt
Documentation showing tax has been paid
or a UK VAT receipt forom seller
the other issue is resale, it is prob worth around £250 less wthout papers
re the import taxes, trust me it does happen
I do trust you, very much so. I'm supprised they have access to a database of watch id's to hand though. They are on top of things. I wouldn't have thought it was worth thier while.
