Apple Watch (mostly) without iPhone?

[KingOfPain]

I have a (probably) strange request...

My father wanted to gift me an Apple Watch a while ago. Back then I could stop him by explaining that new models would be released soon. Now that the next batch of Apple Watches is here, he asked again if took a look at them.
My main problem is that I'm not a fan of smartphones and refuse to walk around with one for no good reason.

I believe an iPhone is necessary to set up an Apple Watch, correct?
Can it be used in conjunction with an iPad later on in any way?
Does it make sense to use an Apple Watch without an iPhone?
What about Apple Watch with cell service? Can this be used on the same call account as the iPhone or does it need a separate one?

I had a simple Casio G-Shock for 25 to 30 years. Had the battery replaced once. When it ran out of juice the second time, some other parts of the watch weren't so fresh either, thus I have been without a watch for several years.
But I seldomly need one anyway. I have clocks at home, in my car, and at work. I only need some kind of timekeeper when I have an appointment in the city. In that case I often take my iPod Touch.
I'm not complaining that my father wants to buy me an Apple Watch, but without being able to use most of its features it would be a really overpriced watch that I'd hardly use...

You have to have an iPhone and Apple Account to setup and use an Apple Watch. The cell version makes and receives calls and texts on the same number as the iPhone, and lets you go into the world without the phone, but you still need it in the first place.

So you’ll have to rethink your smart phone policy if you want to get any benefit from an Apple Watch.

Agree with the above, Apple didn’t design the watch to be phoneless.

Thanks for your answers. I assumed as much, but I wanted to make sure that I'm not missing anything.

Just to be clear, we do have an iPhone (which actually runs on my Apple ID; longer story), but I hardly use it.
Thus, I could set up an Apple Watch, but I'm guessing when using it without the iPhone it's just an overpriced watch, where you cannot use its best features.

I don’t know how to provide tech advice to somebody who has an iPhone and an Apple ID, but “hardly uses it“. And refers to it as somehow communally owned.

Seems like a $50 Timex is what you want.

Does it make sense to use an Apple Watch without an iPhone?

My mother got a cellular plan with her latest Apple watch because she constantly forgets to take her phone with her. This way there's no need.
