Updated review is coming.
A nice and elegant smart watch.
Design / screen
Unlike GWA1, GWA2 has a digital touch bezel. GW has a physics ring but the digital works fine. The screen seems to be clearer and better than GW. Maybe imagination but if so a positive one. The weight is light which makes it superb for the workout. However, the accompanying bracelet is very long and should probably be changed to a silicone band if training is on the agenda (leather and sweat are not nice). The bottom (bottom plate) of the silvery and gold is black while the other part is ... Yes, silver and gold. This creates a bit of an optical illusion: the height of the watch looks lower. Smart! Don't know if this is as clear on the black model. The charger is not the highlight of the clock. GW came with a portrait charger which was advantageous when using steel bracelets. Now it gets a little trickier with a little puck. Works, but prefers a portrait. NO adapter included! Yuk...
People with normal-medium instep and up should choose 44mm over 40. Tested 40 on the arm and it looked very small. Yes, 40 is big for a non-smartwatch and is a decent size among watch lovers if cake perceived it to be something correct. But 44mm is not big. The 2mm missing against the GW46 is not a correct measure to use as the shape of the 46mm housing has other dimensions that make the 46 sickly large and slightly bulky with "wrong" bracelets.
Most things are on Samsung's side, but it has everything you could need, gps, Samsung pay, LTE (more on this below), HR 24/7, waterproof and more. It has Tizen as operating system and NOT Wear os by google. There are drawbacks to both and I actually like both.
The battery ....
With blue tooth, the clock draws about 4-6% / h. With LTE, it drinks (drinks) at 15% / h
This means that the blue-tooth connection for the GWA2 44mm draws as much as the GW46mm does on the LTE 4G / 3G auto. Not good. Yes the battery differs, but the difference should not be of this magnitude.
Ang. battery consumption at LTE ... I sincerely hope that Samsung will fix it immediately, because it is really sunny.
The device also overheats extremely easily when using LTE. Expect it to burn. Then it has stopped its charge and overheated (then turned on in stand alone mode, ie LTE).
The price? A joke, though, assuming that Samsung matches against Apple's square smartwatch. The price draws down 1 star. Also turns off 1 to due to the terribly poor battery when using LTE. Fy ashamed Samsung.
