I replaced my mechanical watch with a G-Shock that lasts ten years without charging of any kind. Even my current Garmin will last a week when charged - it will last even longer if I turn off every single feature.

I use the Garmin to track my exercise - I don't care if the mechanical watch will last all my life if it doesn't do what I want it to do, and it's not even that great at the one thing that it does do.

There aren't a lot of normally-priced mechanical watches that get 1 second/day accuracy. That precision can be admired in mechanical watches, but as I said, it becomes a fun expensive hobby.
