Android Wear: Zenwatch & Sony Smartwatch 3
Got 2; Sony Smartwatch 3 & the original Asus Zen Watch. Android wear was a replacement for my Sony Smart Band which died after serving me very well.
Aesthetically Asus beats the Sony hands down but functionally Sony is my preferred choice (Hence I swear by Xperia devices). Got both from Amazon for less than 5 grand last year September. Shipping could have pushed the price high but I pigee-backed off an ex's friend who was coming from the states to SA. That's where I got the idea for pigeeback.com (social courier service - Google it).
The Sony I can swim with, use it independently of the phone as it has WiFi. It also has a GPS module (not that I ever use it).
Happy with both devices, normally wear the Asus with formal / formal casual and the Sony for weekends. Battery is also much better on the Sony, can go for 2 days whereas the Asus has to be charged to finish the next day.
My pet hate on the Asus is the proprietary charger, if I run out of juice midday and I left the charger at home I'm out of luck. Asus likes to deviate from 'standard chargers', also have the same issue with my Chromebook (yes I love my Google powered devices). Sony with charges with any micro USB charger.
Much as I like the Asus if I had to have one of these I'd take the Sony.
