Used Samsung cellphone watches are available at eBay and Swappa. Both eBay and Swappa act as the middlemen and put you in contact with a seller. Both websites also allow customers to rate sellers, and as such, you can see the feedback a seller has received.
EBay offers filters to help you find the Samsung cellphone watch you're looking for. These filters include color, case and band materials, case size and price range. The watches on eBay can be sold either through auctions or at fixed prices with the Buy It Now feature. In comparison, Swappa has no filters and fewer listings.
