And that's great for you. I was totally against smart watches when they first appeared and didn't see any great use for the Apple Watch.
I eventually bought one and I wear it every single day. Things I do with it:
1. Most important feature is notifications from iMessage, WhatsApp, SMS and a small number of apps that I want notifications from (e.g. British Airways app telling me which gate to go to). On occasion I reply using the watch.
2. Meeting reminders. I go to a lot of meetings. Knowing when they are coming up and where they are is super useful.
3. Activity. I like the gentle push to make me walk a bit more.
4. Timers. Use these often when cooking or making tea.
I have an original Apple Watch. Not sure the Series 4 is compelling for me, but the health features are what will drive me to buy a new watch at some point.
