If anyone thought an electronic device would become a family heirloom they are really clueless.

I think the first good wearable computer ever made has great potential as something people might like to collect. I have the first ever (proper/good) laptop for example. It doesn't work anymore, but I still like having it (and I'd love to restore it some day - just because Apple won't fix it doesn't mean it can't be fixed… it just means Apple isn't maintaining a large stockpile of spare parts anymore).

In 20 years time, I bet those watches are worth a lot of money in good condition. An original iPhone recently sold at auction for $200,000.
