Watch
Clock
noun
A thing that gives you time measurements is a watch or clock. Most people have these in their phones instead of on their wrists now.
The reading for this is pretty weird. 計 is all nice and normal, but 時 is と for some reason. It probably is coming from the vocab word 時 (とき), is my guess. But even if it is, it's shortened, making it a step more complicated. Maybe it's just better to imagine that your watch is a walky talky (とけい) and run with that?
