Can I ask this question? I have an Apple Watch Series 3. It is in mint condition in probably eight months old how much should I sell it for? it is the larger face....Nike and it’s cellular.....
Easiest way is to just go on eBay and check out completed auctions for your watch. That's a pretty good market signal for how much it's worth. Be forewarned that the Apple Watch does not hold its resale value well.
