@s55 To answer the question: Pebbles is by far the best smartwatch, period. Okay, it isn't what you'd call or consider 'fancy' and/or 'cutting edge'. But it can last a whole week on single charge, and is pretty affordable. Whereas You'd be lucky if your Apple/Samsung/Motorolla Watch last just 3 days!
Here's something that's besides the topic: Smartwatches are a technological dud & shall soon start walking the path of extinction! They most likely never, ever become mainstream and are a nichie created solely for computer geeks and freaks! As an old school guy, I honestly don't see any usefulness in them! Let be frank here, Is it really THAT difficult to 'whip-out' a cell phone out of our pockets? Huh? Doesn't make any sense to me... I'd rather get a nice mechanical ROLEX sans batteries, electronics, circuitary and 'wizardry'! Now that's a PURE wristwatch! Just shake your wrist few times to 'recharge' (although 're-wind' is the correct term) the mechanicals once a day and VIOLA! There's nothing quite like the sound of a pure mechanical watch doing Tick-Tock, Tick-Tock, Tick-Tock......
