Not sure what the issue is. The Watch pairs with an iPhone. How you use that pairing is sort of up to you, within the limits of the two devices. Here are a few things I do with my Watch:
1. Unlock my Mac when it wakes from sleep. This is accomplished because my iPhone knows who I am through facial recognition and I have synced the iPhone and Watch and Mac all together under one AppleID. So, with an unlocked Watch and an unlocked iPhone, all I need to do is tap a key on the Mac and as it comes out of sleep the three communicate through WiFI and Bluetooth and open my account for me.
2. Get notifications on my Watch without having to remove my iPhone from my pocket. What notifications depends on the apps and how they work. For example, I have a home security system that alerts my iPhone whenever a door opens, which then triggers an alert to my Watch. So, I know when my wife gets home because the garage door opening triggers the alert on the Watch. This happens anywhere I am in the world, as long as I have Internet connectivity. So I can be away from home and know that she has safely arrived. Or, if a door or window opens when none of us are home, I can then trigger any of the cameras in my home to show me what is happening. Then I can make a decision about calling the police or a neighbor or whatever needs to be done to handle the alert.
3. I have my credit cards in the Wallet application on my iPhone and that is replicated to the Watch. When I am out shopping, I can pay by simply holding my watch near the card reader anywhere contactless payment is accepted. The watch vibrates to indicate the transaction has been successfully completed.
4. I can plan a journey on my iPhone using the Map app and get directions on my Watch without having to take the iPhone out to look at the map. It vibrates and issues tones to tell me to turn left or right as I get near the turn point. Works driving and walking/biking. The tones can be silenced so just the vibration gives the guidance so that you can navigate without even looking at the watch through a noisy environment. Very handy.
5. I get weather alerts on the Watch when storms approach. I also get other things like Amber alerts on the Watch, through the iPhone.
6. I get event notifications for sports through the Watch, which come from the iPhone and the various sports apps like MLB, ESPN, etc. I get a vibration, tone and text on the watch face to tell me when the score changes, for example, for my preferred baseball team.
7. I have home automation, so I can give a voice command through the Watch to open the garage doors, turn on/off lights, set scenes, etc. These are set up on the iPhone, but triggered through the Watch, so I don't have to pick up the iPhone to trigger the actions. It's nice to be able to have Siri, through the watch, open the garage door for me, turn on the lights and start some music as I approach my home.
8. I put tickets for events in the Wallet, and if the ticket has a QR code, I can display it from my Watch, again not needing to remove the iPhone from a pocket. I haven't tried boarding passes, but I think that works as well, if the pass is in Wallet. I will be testing that in a few weeks for a planned flight.
Does that help? It's just a start, the watch is also a handy timer, alarm clock, night light, flashlight, even a Photo album if I download the images to it. All without having to touch the paired iPhone, so I get these things with the iPhone in a pocket. Personally, I don't use it for music, but I know folks do.
