Want to buy Apple Watch 2nd Hand

I bought iPhone 16 Plus 5 months ago, and so far very impressed with the device. I have earphones of OnePlus which goes along with it very smoothly.

But I want to buy an Apple Watch.

Won't be able to buy a new one because don't want to spend a lot again.

Anyone here, who is willing to sell their Apple Watch.

Should be working properly and in a decent condition, with box, I'm interested to buy at a considerable price.

Thanks in advance.
