Confused about Watch App Store

Probably a stupid question but haven’t been able to find answer in Apple docs: I’ve added a watch component to my phone app. Watch part uses only a small part of phone app, not the whole thing. It’s set up to be able to run independently of phone app if desired.

Question: When I submit the app, will the watch part be a separate item in the App Store along with the phone/watch submission? If someone wants the watch version and not the phone part, will they be able to find it in the watch section of App Store? Or should I create a separate watch app also that has no phone component in addition to the watch/phone combo?

For this app, I can see how some people might not be interested in the whole phone/watch combo but might like just the watch component.
