oh, like a watch

Except the battery on a quartz watch lasts years, and the battery on an Apple Watch lasts 12-18 hours.

Never mind that most mechanical watches are self-winding.

Self winding just means "needs to have the time reset after 2 days unworn". I wonder if an unworn Apple Watch would last longer?

So wear it every day, get an device that keeps it wound, or just shake it for 30 seconds a day.

Full disclosure, I'm a mechanical watch nerd, to the point that I enjoy repairing them. So I'm a bit biased towards them.

I have a few of them too, but let's be honest when it comes to their limitations. How is a watch winder any better than the Apple Watch's charger?

If you forget the winder you always have a backup winder.

No, my kinetically charged watch can go weeks unworn without exhausting its charge or losing accuracy.

Not that it matters really. I wear it every day.

Automechanical watches self charge from wrist movement. Quartz batteries last years. They are not comparable to smart watches, which need to be charged often.

My garmin fenix is a bit more bearable as it lasts about 2.5-3 weeks on a charge.

2-10 years is very different from 1-2 days though!

(Not to mention solar watches)

I have a solarwatch that I can't use in the winter time, after moving up north, not enough sun light to keep it charged =p

I'm surprised, my solar G-Shock [GAW-100B-1AER] never dips below "H" charge even on the darkest winter days.

You can charge them under a lamp, too! Regular indoor lighting charges them too, but slowly

My Citizen and Seiko solar watches are good for months after getting a full charge... they say ~6 months and that seems about right

I have a citizen eco drive solar watch i got 16 years ago. Never needed to change or recharge the battery.

And I live in Norway just below the arctic circle so artificial light must be enough to charge it.
