First Impression:

While unpacking, the No.1 Sun S2 surprised me with its heavy watch body. It is made out of polished metal, no plastic like assumed partly before. You also notice that because of the weight (88 g in total) and the cool touch of the metal. Unfortunetaly the metal watch band at my silver version is quite light and does not have the same high quality impression as the watch body.

The top view of the No.1 Sun S2

The display is nearly completely dark in the powered off state, the transition between the display and bottom black border (more on that later) is just noticable at strong daylight. The dark black watchface while being in standby or powered off gives the watch a fancy look in my opinion.

Camera and Button

On the right side you can find the camera and the control button. The camera is hidden very unobtrusive in the “winder” of the watch. Friends just discovered the camera after being told where it actually sits – solved very discretly No.1!

The Microfone

The microfone can be found on the left side. The position does not seem to be chosen randomly: The speaker is placed at the opposite and is speaking in the opposide direction.

The Bottom

On the bottom 3 features are placed: The USB contacts, which can be accessed with a normal microUSB cable via the included charging adapter shell. Also the heart rate monitor is placed on the bottom. At last, the the speaker is placed there as well. The metal watch band is closed with a folding clasp. The watch band is unfortunetaly quite rattly and not made from solid metal. At least the watch band can be adjusted in the size. My personal small highlight is that the watch band can be exchanged with standard watch bands – finally a watch with this feature!

The charging Shell

The Sun S2 is connected and charged with the help of the included charging shell adapter. Comfortable: The shell is kept magnetic at the bottom of the No.1 Sun S2. It even has a hole for the speaker, so that the sound can be lead out to the side, in case you want to use it while charging.

OS/Launcher:

The No.1 Sun S2 does not run like on Android Wear but on a Nucleus OS variant from Mediatek. If the watch is in standby it can be turned on by pressing the button (or via a “look-at-watch-movement”). After that you will see one of three possible analog watch faces. With a swipe the mainscreen is entered.

The main screen

On the main screen a small notification bar is placed on the top, showing the battery status, BT connection and the active profile. Beside that, two shortcuts are available which can be configured with any app installed on the watch. An additional swipe opens the main menu.

The main menu

The main menu is controlled via swiping. You have to be quite careful partially, because of the size of the display.

All in all the system is intuitive and stable. I did not notice any freezes or similiar yet. The firmware can be updated via flash tool and a pc. No.1 already supplied a first update.

Display:

The display has its pros and cons. A huge improvement in comparison to older generations of China-Smartwatches is the IPS-display. Finally a display with stable viewing angles, the colors stay constant also at a very steep angles. And it is round. I also do not know why I like that fact so much . The probably most discussed drawback is the black bar at the bottom of the display (“flat tire look”). The connections are placed here. Anyhow, this is not something unusual – also way more expensive watches like the Moto 360 have the optical drawback (although smaller). The only possibility to bypass it would be a bigger bezel all around the display, which would contain the connection (like the LG Urbane).

While the black bar is not noticable a lot with dark backgrounds, with white backgrounds it can be noticed even more. If this is acceptable is a matter of taste. Personally, I do not a have a problem with it.

The resolution is average. A higher resolution would look nicer, but in general the display resolution is ok and not too low.

Functions:

The NO.1 Sun S2 offers several of functions. I could not fully test all of them completely, so I will add some more infos here in the future.

-Calling: Works flawlessly. You can search through your contacts and start calls via your smartwatch. The calling is done “via your wrist”. The best speaking quality is reached when you talk quite near to the microfone. Incoming calls are shown on the watch and you have the possibility to accept them directly on your watch. Alternatively you can also switch to the watch during ongoing calls started from your phone.

-Pushing Notifications: Also this is working fine. By default all popping up notifications in the notification bar of your Android are pushed to the watch. This can be filtered directly on the watch or in the app.

-Messaging: Reading and writing of messages are possible. Anyhow, the writing is quite difficult due to the alpha numeric keyboard which overlays roughly half of the display.

-Anti-Lost: If the BT connection is lost an alarm will start.

-Pedometer: Seems to be working quite well, although I will add some more experiences here since I will measure in parallel with the Mi Band. Unfortunetaly there is no possibility of syncing the data with the smartphone,

-Sleep Monitor: Same as for the pedometer.

-Sedentary Reminder: The watch reminds you after an adjustable interval to move.

-Audio-Player: The Sun S2 has a surprisingly good speaker for such a small device. Just in the upper quarter of the volume the speaker starts to distort. Obviously this is more or less a gimmick, but with a way better sound quality I expected.

-Heart Rate Monitor: On the bottom of the watch a heart rate monitor is placed, so it can be measured while wearing it. The accuracy is quite varying. It feels like around every second measurement delivers a kind of “plausible” value. Also here was unfortunetaly no feature included which can push the data to the phone.

-Thermometer: While measuring the temperature also the bottom LED is turned on. I haven’t figured out how you could measure the temperature with this or if it is fake.

-Calculator

-File manager

-Video-Player

-Gallery

-Sound-Recorder

-Stop-Watch

-“UV Measure”: A fake app, which returns an UV value ranging from low to high depending on the time.

Camera:

The camera is placed hidden in the “winder” of the watch. As expected, the quality is quite let’s call it humble. The stated resolution of 300 KP (640×480) seems to real. Inside the camera app some settings can be set: delay, anti-flicker-frequency, contrast, resolution and quality (low-medium-high). You have to get used to take pictures especially at the beginning, since you watch kind of 90 degrees rotated. Here are some sample pictures (take in the dusk):

Unfortunetaly the camera seems to be not perfectly placed in the middle at my device – you can see a circular black blur at the right side of the pictures, probably caused by the borders of the “winder”. The pictures can not be used for real pictures for obvious reasons, but for small James-Bond-like secret snapshots is funny (in my opinion).

Wearing Comfort:

I like the feel of the watch in general while wearing. The metal watch band can be adjusted well to my wrist size. It should fit small as well as bigger wrists. I personally have quite small wrists, so I directly removed four links. Anyhow, a new watch band is going to be inserted soon, not because the old broke, but because I want to try it .

The automatic light-on feature works very well. It does not need a special shaking movement to wake up, but just a simple “look-at-the-watch-movement”.

Battery:

According to the shop the No.1 Sun S2 has a built-in battery with a capacity of 350 mAh. I did not verify this yet, but I will measure it in the future. While automatic wake-up feature turned on and constant BT the battery the battery lasts about a day at my usage. Charging at night is mandatory.

Conclusion:

Despite several drawbacks, I like the the No.1 Sun S2 very much, especially because of its small price. Obviously you do not get a watch which can compete with brand smartwatches at every aspect. But it supports all major smartwatch functions which I use and it has a high quality look. Since the day of arrival it is placed on my wrist daily :) . Especially the high brightness if the display and the automatic light-on are convincing me.
