How does AW / moto 360 behave with no connection?

[GTvert90]

Work no longer let's us carry our phones with us there for the 360 will spend a lot of its time with no phone connection. I'm assuming it will still keep time? I only ask because an early Sony smart watch couldn't. What else? Can you still set timers use the stop watch? Can you use apps that don't require Internet connection like a calculator?
