Apple Watch 3 Reset (touch Screen broken)

Hi, Unfortunately i broke the screen on my Apple watch (it's cracked across the top third of the screen and the touch screen doesnt work in that top third.

So, I can't unlock the watch (buttons 1,2,3 on the passcode don't work. 4,5,6,7,8,9 are all ok). I can't do a hard reset either as the button to press on to confirm the hard reset pops up in that top third of the screen.

Does anyone have any ideas how i can reset my watch/password withought using the top third of the screen? Thanks
