Of popular gadgets, Garmin watches (at least fenix series) can work without any additional connectivity and will do all metrics processing on the device.

I love the great battery life and the lack of required connection on garmins. I had an apple but who wants that daily charge requirement.

Even huami (Xiaomi or amazfit) watches, while terrible for privacy out of the box, can be made super privacy friendly with gadgetbridge. An open source sync app that doesn't even have internet access.

And they're a lot cheaper, thinner and lighter than Garmin has to offer, and run weeks on battery <3
