eBay no longer supports the old "All Lists" link to see all your lists on one page.
If you are using a desktop browser, you should be able to reach your individual lists by going to your Watch List page and clicking on the large "Watchlist" heading to reveal a drop-down menu of each list.
You can also reach a list by adding an item to the list, and then using the link that appears in the blue band at the top of the item page.
