I have a Seiko Titanium dive watch that I have had for 20+ years. It has been banged around a lot. The "glass" is Seiko's Sapphlex. It is very thick and tough. Over the twenty years it scratched once. At the next battery change, the crystal was replaced and it remains unscratched. (The watch still keeps practically perfect time.)
I do used a Fitbit Flex at the gym for a couple of years. (I know, blasphemy!) I had a screen protector but scraped it up dragging it against a wall. I removed the protector and have been using the watch bare for about six months. Surprise! No scratches.
I'm moving up to an S4. I have always wanted an Apple Watch. I'm going to use the Mickey Mouse display.
