Use of proper keywords is critical in any eBay search. What is less generally known (and appreciated), is that it is possible to block items from showing up on a search. Even with, say, "Pulsar LED watch" in the search engine, a lot of extraneous (though Pulsar-related) things show up (mostly printed advertisements). To eliminate those, I use "Pulsar LED watch -ad", and only the listings for actual watches show up. You can put multiple negative terms in the search (not sure how many) in the form object -x -y -z, and so on. It can cut thousands of potential listings to dozens (or less). Anything that usefully narrows the search is a great goodness
