You won't know until you try.
All these people saying the Apple Watch.
I have an Apple Watch (SS Series 3 with cellular) and it has been sat in a drawer since I last had an iPhone 4 months ago.
I don't miss it at all and when I use an iPhone I don't even really like it. But I won't sell it for much now as it's getting on so I just keep hold of it.
IMO it's the most overrated piece of tech ever. But some people seem to love it, so.
Like any piece of tech, it'll fit peoples tastes and needs differently. I know plenty of people who can take it or leave it--they're typically younger folks who never wore watches growing up and just don't get value out of it.
I'm a bit of an old fart that has worn a watch since I was a teenager and my wrist feels 'naked' when I don't wear one so it was a natural feeling when I started with the OG version. Since then, I've come to rely on so much daily functionality and personally love how it can keep my phone out of my hands more often. I love my smart phones and that's the problem. It's very easy for me to just get sucked into it when only intending to do something simple like checking a message or email, etc.
For some context of my personal use, I use my Apple Watch for the following, usually every day and very often without my iPhone on me:
- Email and message 'triage'--lets me know if I need to respond immediately or can get back to it later
- Answer calls, either via speaker or with wireless earbuds
- Weather via Carrot
- Timers and alarms
- Fitness tracking either using Apple's native Workouts app or Strava and Activity tracking in Apple's app.
- Listening to podcasts via Pocket Casts
- Listening to Audiobooks via Audible
- Listening to Music via Music or Radio apps
- Map navigation (Google Maps or Apple Maps, the latter especially if I don't have my phone with me)
- Checking my family members location using Find My
- Reminders and Appointments (Apple Reminders app and Fantastical, respectively)
- Grocery shopping using AnyList
- Endless TFA for personal accounts and work logins via Authy
- Access frequently used passwords via 1Password
- Smart home activity using Apple's Home app (lights, garage door most common). I can even see my security camera feeds live on the watch
- Just about every payment now via Apple Pay (both in person at merchants or to authorize web payments on my Mac). Wallet app also has my gym card (when that was a thing) and Starbucks card
- occasional quick calculations using the onboard Calculator
Again, I genuinely do all of these tasks just about every single day, some quite often on the Watch and I can do all of them (except for navigation using Google Maps) without my phone as I have the cellular model. I've been on a bit of a mission to see how often I can go without carrying my iPhone, only using my Apple Watch and if it weren't for the lack of CarPlay, cameras, and a bit better battery stamina when using it over cellular on its own, I could go full on 'Dick Tracy mode' and use just the watch. It pretty remarkable how much of my daily needs can be fulfilled by just the watch.
I completely understand how many don't see the appeal but as you can see, it's an invaluable piece of tech for me. There is nothing else in this tech category that can come remotely close.
