Great watch. Amazing build quality and sturdy. Love the features. But it's for sure an outdoor watch and the screen looks great in the sunlight, super easy to read. At night, the light is very bright. But indoor conditions with low light or shadows outside or inside a car, it's hard to see at first glance. Just be aware of that.
