I live in the UK and the cheapest I've found the GW5610, which was released in June I think, is for £77/$125 on Amazon.co.uk.
On eBay I found a GW5600, perfect condition, but two years old (rarely worn) which is ending tomorrow with no bids and a starting price of £40/$65.
I'm 15 and I've never bought a watch before; would buying the used watch be a good deal? I've heard aside from the strap (5 vs. 6) there's little difference between the two models.
Considering there's no bids with only 22 hours to go I'm thinking of maybe messaging him and offering £32/$52 instead.
Thanks for the help.
