It will be more convenient if there is "clocks" in glances, but I can't find clocks in glances editing
Do you mean having more watchfaces? If so, then that's not available. You have to use Menu » Watchface, if you want to switch to another watchface.
Well, I mean I want to add alarm or timer in glances, in that case, I can only touch the screen to use timer
I don't wanna press any button to get to timer

You could set a hotkey. I'm using the start/stop button. Long press and it shows the timer.
