How can I disable the time showing on the right hand corner of my apple watch?

This might be a function of the watch face you have selected, or it might be something dismayed by a Complication in the selected watch face. There will be a solution, but from the information you have shared so far we can't even try to guess.

The best solution might be to get a screen shot or photo of the watch (to show the problem) and share it here in the thread so we know what you are trying to fix.

I've been looking for a fix for this for ages, DRIVING ME INSANE
