From what I've seen in written reviews and user forums, the solar can reduce the rate of discharge but isn't realistically going to charge up the watch. It could be enough to offset daily basic smartwatch use if you spend time with it exposed to bright conditions while you wear it.
Setting it out in bright sun is likely to just overheat it and then it won't charge. On your arm, you act as a heat sink compared to if it is left on a sunny surface.
Based on your comment, I'd error on the side of gimmick then. =)
And the watch will report amount of solar energy gathered ... Somewhere.
I'd say the main problem is that sometimes the watch stays on battery so long I forget it needs a charge at all ...
It looks like a great watch but compared to my Fossil HR Collider: far more expensive, color screen instead of e-ink.
If they made something that looked well with a suit too, maybe I'd bite.
Or have they and I'm just not up to date with options?
Consider for example https://res.garmin.com/transform/image/upload/c_limit,dpr_1....
Noted, thanks.
I've clicked around a bit and i could find just one metal bracelet. And zero leather (even fake).
I know you can generally swap bracelets* - if they're standard - but there's enough plastic garbage in the world if you ask me.
* easy with leather, but if you want a metal bracelet that matches the metal body of the watch exactly, hard.
Very much like this watch, especially with aftermarket Velcro strap. It's also surprising how useful the builtin flashlight is on a watch, much more convenient in everyday use than one in a phone.
