I use the Watchlist to corral potential purchases and sort them out at the end of a buying-browser session (which can last all weekend). I might watch for a days if it's something I want but feel the price asked is a bit steep, so I use Watch as a hold in case I find a better price or condition (which feels like it happens only 50:50), or as a reminder to buy come pay-day, or if I find the item for the same (or even fractionally more) from a seller I buy from regularly.
I don't use the Basket to sort as I once accidentally (on a different platform) bought them all before I could sort. I've received only a few offers, all from the same seller (and accepted).
I don't know how many others do the same as me. I know one or two who do it sometimes.
Isn't that how selling goes whether online or in a bricks & mortar shop - you can't expect to sell to the first person/first Watcher. At least with Watching they (or rivals!) have got your item in mind.
Also, a Watcher who doesn't buy might be an actual buyer another time (I've done that, quite often).
It's not as if, as in bricks & mortar shops, a potential buyer has irritatingly opened your item and handled it without intending to buy.
