I am not able to pair my Apple watch 3 to my iphone XS max

Hi.. After taking update IOS 13 on my phone, my watch got unpaired with my phone. When I am trying to connect my watch, in Manual pair option after selecting my watch on apple watch app it is asking for a 6 digit code that is displayed on watch screen. But I am not able to see any code on my watch.

Please help as I am able to pair my watch now more than a week.

Thanks for help in advance!!!
