It's also the only timekeeping device that will still work after three days away from an electric plug, and the only one you would wear all you life.

1 second/day is 10 PPM. Reaching that accuracy with only mechanical means in a device small and robust enough to be worn on the body is something to admire, not to fault for its limits.

Quartz watches go years on a small battery, and keep better time.

Sure, it's admirable engineering, it's just most obsolete. And that's ok!

The role of watches as jewellery has kept mechanicals going far more than practicality.

Lasting years on a battery is easy.

Why not both?

Advertised at +-15 seconds a month, but in reality it's much better than that.

I get your point, but I can easily get >2 weeks out of my Garmin Fenix or over a month if I put it in battery saving mode.

It won't do that in 5 years, let alone 10. You'll be unlikely to find a replacement battery, too.

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.

Digital watches also exist, last years on a single cell and some have a solar cell to extend that. A cheap Casio F-91W is accurate to 1 sec/day and I imagine you’ll find others that can do better.
