Always remember, watchers are NOT buyers. Like another said, there are many reasons people put items on their 'watch' list. Some may be other sellers, some may be possible buyers, who really knows?
Your items are higher priced, which tells me that people may take a bit more time before deciding to buy, thus putting them on their watch list while deciding.
Most of my items are lower priced, and often times I have items sell that didn't even have one watcher. The number of watchers is simply a guide to how many people 'might' be interested in your item, their reason for interest in unknown. But that also shows that you are getting views, and interest, which is exactly what you want 🙂
Selling on eBay is a game of patience.
