How can I mute my Apple Watch but still keep all the sounds on my iPhone?

Hello. How can I mute my applewatch but still keep all the sounds on my iphone. If I mute my watch now, then I get no notifications with audio, on my phone, only ringtone. and if I have sound on the watch, both my watch and phone ring at the same time as sound on.
