They’re going for $1500 used on eBay. I checked at my local Apple store and no dice. It was pretty much sold out at all stores before the series 6 even released. Apple did a good job selling down their stock this year.
Good question. The problem you’re facing that I mentioned in another thread, is that ceramic owners now realize that they have something that likely is never going to return, but the prices will be inflated and if you want a ceramic Edition, check Facebook marketplace locally in your area (which will probably be more of a rarity if you find one that way), but eBay has the widest audience. The problem with eBay, is make sure you check the authenticity of the sellers for background for credibility and make sure it’s also not a refurbished ceramic Apple Watch through a third-party retailer.
