Recommendation on how to sell a watch

[Jojoshop]

Let me first start with this. I’m not thinking about selling right now; this is more a curiosity just in case I want to sell one of my watches in the future.
Some online stores ask for pictures and then for the watch to be sent first. There some horror stories of price cut or expenses to get the watch back.
For an owner like myself not looking for a quick buck just fair price and flawless transaction, what will be your recommendation?
