Wow, that's a beautiful watch first and foremost, and a "smart" accessory second. It reminds me of the Bauhaus style of Nomos and later on Stowa, both held in extremely high regard by the watch community.
$450 is high for a smartwatch, but low for a watch in general. Nomos watches cost thousands. Granted, that's in large part to their in-house mechanical movements. But $450 is certainly not unreasonable for a high quality quartz watch -- see Seiko and Citizen. And this has the aesthetics to compete with the best of them in my humble opinion.
I have a Moto 360 and I stopped wearing it a bit over a month in. The extra features it has aren't very useful to be completely honest, and it's a bit bulky, having to charge it daily was really a drain, and it just felt flat-out fragile. I was afraid to even wash my hands while wearing it.
Lack of Android support is unfortunately a deal breaker for me right now, as I don't have an iPhone.
