Great watch for the price, you can see it at a quick glance in the darkest night, you don't need to look for a button to press to illuminate it.
its not bulky, good size i think.
i had not tried to dive with it, but i don't dive, so, i don't really care if it is waterproof or not. works fine, it tells the day and hour and I can see the hour with a quick glance in the bar without having to get my cellphone from the pocket or trying to press buttons to illuminate the dial..
