Smartwatch or Rugged Smartwatch?
Coming from normal smartwatches, the Rogbid Tank S2 Smartwatch was the first rugged smartwatch I tried. The benefit of a rugged smartwatch is that while it may not look as sleekly designed as a normal smartwatch, you can just wear it and pretty much forget about it. The Rogbid Mille is another rugged smartwatch like the Tank S2 smartwatch, but with a focus on design and a curved screen.

This watch retails for around $99 USD, which is not the cheapest option when it comes to smartwatches, but still reasonable for a rugged watch, which has MIL-LTD-810 certification.

Package Contents
In the box, you get the Rogbid Mille watch, small screwdriver, user manual and proprietary charging cable, so don’t lose it.
Rogbid Mille Design
The watch has a slightly rectangular design, with the height of the watch around 5 mm taller than the width.
The right side of the watch has a plastic crown that is both rotatable and pressable, and which produces audible clicks while it is rotated. There are also two plastic buttons located above and below the crown.
The exterior border surrounding the screen has what Rogbid calls a sand gold color. There is also a black version too. The watch has a mostly matte type of finish overall to resist fingerprints. There are some embossed stars on the exterior around the screen. There are also black screws used to secure the watchbands, which can be tightened with the supplied screwdriver.
The underside of the watch has the sensor and two metal contacts to enable recharging the watch battery.
Wearability & Comfort
The synthetic rubberized watchband is pretty comfortable for all-day wear. The watchband has soft feel and I didn’t experience any pulled hairs from the watchband. It’s a lightweight band that is pretty durable and great to have for all day wear.
The watchband has two retention bands to keep the unused portion of the watchband secured and out of the way.
My wrist size is around 6.4″, and even with a smaller wrist, the watch didn’t seem overly big on my wrist. The watch’s height is approximately 1.3 cm, so while it isn’t the thickest case, it’s pretty sizeable. The design doesn’t have any sharp edges to get it snagged on clothes.
Build Quality
Rogbid’s website certifies that this watch meets the MIL-STD 810G – 2014 standard, which means this watch has been tested in various areas, such as heat, cold, shock, vibration, humidity, gunfire shock and other tests, which total 29 tests! I didn’t test it in these areas, but I did test it by submerging it in water and using the buttons, and it worked without any issues. The Mille is rated for 5 atmospheres of water pressure or 50 meters with its IP69K rating.
It can also withstand temperatures of -40 C to 70 C, along with 96 hours of salt spray resistance, ice and freezing rain resistance, so yea, it’s pretty tough and perfect for those who will be in extreme environments or can’t worry about babying their watch.
Screen, Apps & Settings
The screen features a 60 Hz refresh rate which is decent when swiping between screens. I also found the screen size easily usable, and it gets plenty bright with around 400 lumens of maximum brightness. There are handy dials to cycle through such as quick settings, weather, stopwatch, alarm, calculator, etc.
I really enjoy using the Weather dial because it can be scrolled vertically to see the weather for the current day and the rest of the week.
The watch has tons of apps, but I’ve stuck to the health-tracking apps. Some utility apps include a calculator, flashlight, find phone feature, remote shutter, voice assistant and more.
Some of these apps can be set as “Favorites” or shortcuts so that as you swipe to the left, you can get quick access without going into the central app drawer.
Pictured are some of the main health metrics you’ll be looking at most of the time, either on the watch or the accompanying DaFit app. You can quickly swipe left on the watch screen to easily switch between the above screens without going into specific apps.
Rogbid mentions that health data is for reference only since the watch is not a medical-grade device. While that is the case, the watch was somewhat close in accuracy to my Withings ScanWatch when measuring Sp02 by about 2 to 3 points. However, it was off by about 8 to 13 BPM. My ScanWatch does not offer blood pressure readings, so I cannot comment on Rogbid’s accuracy there.
The app connects to the watch by Bluetooth, like most other smartwatches. While the app provides many metrics, I checked them on the watch directly since it’s quick and easy to do so, and I can pin certain favorite apps or screens.However, the app is handy for downloading or setting more watch dials that are pre-installed on the watch.
In addition, certain watch dials can be customized further in the app, such as setting the text color and position, which are not customizable from the watch settings directly. New dials can also be downloaded via the app pretty easily as well.
The app can also be used to quickly see all apps that can be chosen to push notifications to the watch. The app is also necessary for updating the watch software.
If you’ll be relying on the watch for notifications, the vibration strength is great and also adjustable.
Sport Modes
This watch features one of the most comprehensive lists of sports or exercises I’ve seen. There’s everything from normal walking or running to Yoga and even Golf! You’ll easily find a matching exercise or activity mode if you can’t find it on another smartwatch.
Unique Features
I’ve used some smartwatches with pretty quiet speakers. So when I saw that this watch had speakers to allow for taking or making calls, I was a bit skeptical about the audio quality. I have to say; this is the part that impressed me the most. The speaker gets loud for being on such a small device and stays decently clear even at max volume. In fact, I played music from it, and it did surprisingly well! I can see this being useful listening to a podcast and having the sound emitted from the watch instead of the phone.
The voice assistant feature also works very well too.
Battery Life
Battery life is rated for about 15 days of working time and 75 days of standby time. In my testing, I got around 13 days, so I’d say it’s a pretty accurate claim, especially since I spent some initial setup time playing with the watch to get acquainted with it. Charging takes around 1.5 hours to top fill up the 520 mAh battery.
Summing Up
The Rogbig Mille smartwatch comes in at around $99 USD. There are cheaper smartwatch options out there, but for the durability, tons of sports modes, surprisingly loud speakers and tons of sports modes, this is decent value.
If you want a watch that will take a beating, last for around two weeks at a time and offers decent value, the Rogbid Mille smartwatch should be on your shortlist. While it is quite durable, any watch that does not have a sapphire crystal dial will be subject to scratches over time, so keep that in mind.
