Does it use just standard watch bands? It looks like it, but I didn't see it mentioned.

One of the things I find ridiculous about other smart watches is that they use proprietary bands. When I found out that people are paying $60+ for a silicon band for an Apple watch, it blew my mind. Also that people put screen protectors or cases on their Apple watches because their $500+ watch doesn't even have a crystal lens, and is prone to scratching.
