Great device. Still a lot of potential.

Have the Gear S since few days. But bought because of the availability at ComTech the clock. I am pleasantly surprised. Great design. is not so big and flashy wrist.
The Gear S is very high quality. She feels the curvature perfect the arm. They did not fall on the SmartWatch.

The S was the Gear works only with Samsung smartphones already always clear. I do not understand as some reviews.
The clock has the Samsung OS Tizen. There is no Android Wear. If you do not buy a Samsung mobile phone should be LG G3 or Moto360. This clock will only work with the Samsung App Gear. And this is only in the Samsung App Store.

The clock is a supplement to the mobile phone. We learn now in a stripped info and message if s worth the cell phone out of his pocket to take. WhatsApp emails messages, appointments can be watched on the clock. But will not be answered. Images are not displayed in the mail. With WhatsApp but already. There are some apps that can be installed directly at the clock.
WhatsApp but comes from the smartphone.
If you insert a SIM card into the device then you can write and receive phone calls and SMS. Watch the news. But nothing more. So it is already necessary the clock with a Samsung mobile phone to use to utilize the functionality.

The language assistant works very well. Hi Gear and say the SVoice starts where you just say what you want to do.
Navigate, make phone calls, emails, etc. Is super show. The pedestrian navigation with HERE Maps is as always top.
Also the phone is very good. Volume is good. Voice quality also.
Display brightness very well. I have asked the brightness to automatic. Always easy to read.
Heart Rate Monitor, UV sensor on Shealth works.
Battery lasts for much gimmick at the beginning loose by one day. In normal use, the battery is safely hold two days.
Bracelet with snap closure handy. The clock is not cheap and clearly I lack compared to other watches with Android Wear. But I am very happy with the Gear S. I find the whole solution as a complement to mobile very praktisch.Ich think that because Samsung have optimized a lot of updates. But it is halt ne Samsung Gear solution. Without Samsung phone is not recommended.
I can recommend the clock with a clear conscience.

Update 17/01/2015

I now use the Gear S exclusively in remote mode with my grade 4. I have the third SIM from my Multisimvertrag in S. Gear
Have put on Edge receipt. 3G is unnecessary and takes a lot of energy.
I get all the emails and other messages (WhatsApp, BBM)
When installed on his phone the Notification Center can be answered normally WhatsApp messages on the Gear S without the phone dabeizuhaben.Auch the Opera Mini browser is pretty good. It displays pages with text on which the Iphone6 ​​Safari browser can not show. (I tested with my own company website)
Then I bought the headset Gear Circle. This is the only headset where voice control Profile of Gear S fully supported. Is indeed a private Bluetooth profile.
So the solution to the clocks Gear S for me is top. As a man, one has always to have handbag to his cell phone there. In women, this stand-alone capability is probably not so important.
I now on the phone a lot for business with the clock in conjunction with the Gear Circle.
The Gear Works therefore stand alone. My grade 4 must stop somewhere in the network are turned on.
This can no clock and that is absolutely crucial for me at all as a clock to use.
The Apple Watch must be always connected to Bluetooth with the iPhone. And they will only go with an iPhone at all.
The solution from Samsung is thought out and the right way for me. Whether the clock now with Tizen or something else is running anyway sausage. What is important is where the S Gear app running on your phone. The can theoretically run on any platform if Samsung wants to.

When I set use with calls and many emails and messages and EDGE so I just came over 12 hours with the battery.
With Bluetooth, the battery 1,5Tage enough in my experience.
