Vintage Apple Watches - The Original Apple Watch

With the (re)advent of the Apple Watch, eBay went nuts for the vintage blue bezeled 1995 Apple Watch, billed as the Original Apple Watch. Several went for thousands of dollars. I started looking at my old Apple watches, trying to remember when we got the ones we had, but that was useless, so I hit the web. I came across an article at
My Favorite Apple with pictures showing a 1986 Apple Watch in a 1987 Apple magazine, black with the rainbow Apple logo, in a Men's and Women's version. It is the earliest watch the author could find. There was no mention of value, and I am curious what a real original Apple Watch would go for. Because I need to insure one.
