Cannot see Apple Calendar on Connected E4

Hi,

I have the apple calendar notifications slider set to on in Tag Heuer application on iphone, and calendar app itself has all notifications on. However I cannot see any of the apple events on my watch .

I've spent an hour searching the net, but can't find anything

Any ideas please, I've only had it a couple of days , however if it won't show my iphone calendar (which it says it can) then it'll be no good for me
