Not visible
The watch is great, but you cannot see the numbers very well. It is very hard to tell the time without pressing the light several times.

Great watch, but not an everyday wear.
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.
