REVIEW – Along with being a tech junkie, I’m definitely a watch guy thru and thru…mechanical, quartz, digital, fitness, smart, luxury, beater, etc. I have tried many flavors of timepieces and enjoyed the experience of wearing them all. Currently I waffle between nice mechanical watches and their high-tech, smartwatch brethren. Late last year Julie reviewed the TicWatch Pro, an android/WearOS smartwatch that Mobvoi released as their flagship device. Recently Mobvoi released several less expensive variants, the TicWatch E2 and S2 of which they have sent me the more hardy, sport version the S2 to checkout.

Backstory and details: I have used more than my fair share of smart-/fitness watches over the years from simple stopwatch function to GPS/speed/distance/heart rate monitoring to the latest Wear OS, Tisen, and Apple Watch. My current smart devices of choice are the iPhone Xs Max and Apple Watch Series 3 amount others. So, this review will be more skewed towards an iOS Apple user’s experience of the Mobvoi TicWatch S2 and Wear OS.

What is it?

The Mobvoi TicWatch S2 is a sport-centric smartwatch powered by Google’s Wear OS with a built-in heart rate monitor, internal GPS, and hardened to military specifications, all combining for a smartwatch ready for whatever epic workout you throw at it.

What’s in the box?

• TicWatch S2 android smartwatch
• TicWatch Charging Dock
• User Manual

Design and features

The TicWatch S2 has a 1.39-inch diameter, 400 x 400 pixel AMOLED display. The screen pops and is bright enough to see outdoors, rain or shine. Its resolution is sharp and you’ll have to strain to see individual pixels. The overall viewing experience is very good. That said, it lacks an ambient light sensor so you’ll have to adjust the brightness manually. Though at moderate brightness, battery life easily lasted a day of normal use with an hour or two of exercise (with GPS and streaming music via Bluetooth). To save/extend battery life, the S2 has an always-on display mode (far left pic), which shows basic time and battery percentage when the watch is by your side or is not in use. When you rotate your wrist, the watch face comes back to life. According to Mobvoi, the S2 has two days of battery life and for the most part I agree.

The Mobvoi TicWatches are compatible with both Android and iOS devices. Setting up the TicWatch S2 with my iPhone was easy enough though a bit frustrating compared to an Apple Watch. The Mobvoi iOS app epically failed and has yet to work. I finally gave up and used the Google Wear OS app that got me up and running without too much hassle. Though using the two together isn’t as seamless as living completely in the iOS ecosphere but it does work.

The TicWatch S2 case is made from a rigid black polycarbonate that is not only durable but lightweight as well. The overall build quality is good for a plastic smartwatch. The TicWatch S2 is relatively hardy, built to a MIL-STD-810G U.S. Military rating for durability and ruggedness. The bezel has a nice carbon fiber look with minutes numbers (15/30/45/60) and tick marks etched into the plastic…but since the bezel does not rotate, they are more for show than anything else.

The TicWatch is a large smartwatch measuring 46 millimeters in diameter…that’s Breitling big. The lug to lug wingspan is nearly 52 millimeters. I have a 7 inch wrist (relatively average IMO) and the lugs hang over my wrist by a few millimeter on each side.

The S2 sits 13 millimeters tall on the wrist. The overall dimensions (46.6 x 51.8 x 12.9) make the TicWatch pretty clunky.

Here you can see the S2 compared to the Suunto Elementum Terra and 42mm Apple Watch Series 3…definitely not small or petite.

That said, at less than 2 ounces the S2 is lightweight and comfortable to wear. When exercising, you hardly know this fitness watch is on your wrist.

In addition to the watch’s face being a touchscreen, there is a single button on the right side of the watch to help you navigate the operating system.

The band is made from a soft, silicone rubber that is comfortable and flexible.

It’s length fits my wrist very nicely.

The bands lug width is 22 millimeters and has an easy removal pin, making swapping the band effortless.

The heart rate sensor is solid and compares nicely to both my Apple Watch and sensors on my elliptical machine. The GPS function and accuracy also compares well to my known routes and GPS on my Apple Watch. It is quick to locate and lock onto the satellite’s GPS signal.

The S2 charges via a propitiatory charging pad with four metal pins that must make contact with the four points on the back of the smartwatch. This is a bit old school compared to the standard wireless charging that most smartwatches use today.

The TicWatch S2 is powered by a Qualcomm Snapdragon Wear processor, running Wear OS. My main criticism of this watch is definitely how laggy and glitchy it is. Many apps took multiple attempts to get them to activate/startup and that was the standard vs the exception. I found the Tic exercise apps mediocre at best. I ultimately downloaded Google’s fitness and media apps. That in of itself was a painful experience, then downloading my running music/playlist took forever with several crashes.

What I like

• Inexpensive Wear OS device
• Solid utilitarian design
• Bright clear touchscreen
• Sweat-/weather-/waterproof
• Heart rate and GPS sensors
• Solid battery life (nearly 2 days)
• MIL-STD 810G durability certification

What needs to be improved

• Laggy, mediocre performance
• Regularly crashes
• No NFC or LTE
• No Google Pay
• Doesn’t wirelessly charge
• Mobvoi software is completely unnecessary

Final thoughts

I hate to say it but the TicWatch S2 is fine and that is where the sentence stops. That said, it does work and gets the job done just with a few bumps along the way. It is clunky in form and operation, definitely irritating/frustrating to use at points. But from what I have read, mediocre to cr@ppy performance applies to every Wear OS smartwatch available today. You can find the Apple Watch Series 3 and Samsung Tisen watches at or below $200 these days, both with better performance. At $179, the TicWatch is not a great value considering other options currently available.

Price: $179.99
Where to buy: The TicWatch S2 is available on Amazon or directly from Mobvoi.

REVIEW – Smart watches are one of the hottest tech trends in recent years, but one of the main drawbacks of these popular “wearables” with their wealth of features is their battery life, or lack thereof. Many smartwatches require daily charging, which can be a bit irritating and sometimes inconvenient.  That’s why the Matrix PowerWatch X was developed.  It’s a smartwatch that is powered by the wearer’s body heat. Let’s check it out!  Gadget on!

What is it?

The Matrix PowerWatch X is a multi-function smart watch that is powered by the wearer’s body heat.

• Microfiber cloth

Design and features

First thing I noticed about the Matrix PowerWatch X: It looks wicked tough.  Matte black case, black LCD face, matte black strap.  Ironically, one of Matrix’s other PowerWatch models is called the “Black Ops,” but I actually think the PowerWatch X looks even more black ops than their Black Ops.   The display appears to be an LCD screen, but I suspect it may be an “e-ink” type display, which would make sense because I understand that e-ink displays typically use less power than other LCD displays.  Also, I think the face is likely a mineral glass material, not sapphire crystal.

The PowerWatch X is quite thick at 13.5mm, which honestly doesn’t bother me at all, since I like big, thick watches, but others may find this undesirable depending on your wrist size and personal preference.

The top and bottom of the case, near the strap ends, have a grille-style look that is a bit reminiscent of Darth Vader’s mouth, which as an old-school Star Wars fan, I can totally appreciate.

The PowerWatch X’s crown is actually used to cycle through its various modes by rotating it clockwise.  More on this below.

Above is a closeup of the PowerWatch X’s stem, with its thick knurling, and one of the four screws around the perimeter of the watch’s case.  My understanding is that these screws are mainly cosmetic, but I’ve read many comments online that these screws are not secured well in the aluminum case and many PowerWatch X owners are finding that one or more of their screws are spontaneously unscrewing and falling out.  Although this did not happen to me, it is something to be aware of.

The technology employed by the PowerWatch X to generate power is called thermoelectric generator (TEG) that sense the wearer’s body heat and converts it into energy that charges a battery.  In order to function, TEGs need a hot side and a cold side to operate.  The “hot side” is the circular aluminum back plate seen in the image above.  The “cold” side is the entire metal bezel and body of the watch.  The “hot” and “cold” sides are physically and thermally separated and from each other by a layer of insulating thermoplastic.  The TEGs then harvest the heat flowing from the “hot” side to the “cold” side and convert this heat into electrical energy that powers the watch’s battery.  This means that the greater the relative difference in temperature between the ambient air and the wearer’s skin will allow the TEGs to generate energy faster, whether this means a lower air temperature, such as on a cool day, or a higher skin temperature, such as when the wearer is active.  In fact, above 90 degrees F, the PowerWatch X is unable to charge.  So if you live in a high-temperature climate, the PowerWatch X may not work for you.  I have to be honest here and admit that, as a mechanical engineer who has taken both undergraduate and graduates coursework in heat transfer, this is geekishly awesome tech.

Also seen above, the PowerWatch X has a 24mm wide black silicone strap that is soft and has a bit of stretch to help keep it flat against your wrist without feeling uncomfortable.  It utilizes a really clever and easy-to-use set of quick-release pins which make removing the strap from the case’s lugs very quick and simple.

Let’s dig into the PowerWatch X’s various modes and functions.  Above is the default mode screen that shows time, date and day.

Rotating the crown clockwise while in the default mode screen changes the display slightly.  The date and day disappear and are replaced by two temperature readings: Skin Temp and Case Temp.  The bars on either side of the display in this mode show how much charge the watch is receiving at that moment.

Pressing the top button cycles through the PowerWatch X’s modes.  The first, Daily Activity mode, actually has two screen, as seen in the image above. The first screen shows distance traveled (on foot) in small print at the top, steps walked in large print in the center, and calories burned in small print at the bottom; all of these values are for the current day.  Rotating the watch stem clockwise switches to the second Daily Activity Mode screen, which shows the amount of sleep in the previous night’s sleep session.  The step, calorie and sleep counters reset every night at midnight and each day’s totals are sync’d with the smartphone app.

Pressing the upper right button again switches to the next mode, Running Mode, which is then activated by pressing the bottom button, which acts as the start/stop.  Running Mode displays the duration of your run in minutes and seconds in large text in the center and the distance in miles in smaller text above.  Since the PowerWatch X does not have a GPS (that I am aware of), this mode seems to be calculating distance based on your steps while running.  It seemed to be fairly accurate compared to the GPS watch that I typically use.

Pressing the upper The next is Stop Watch mode, which is a simple stopwatch that records in minutes and seconds only, not fractions of a second like most other digital stopwatches in the world, which is a bit disappointing.  Again, the bottom right button is used as the start/stop button for Stop Watch mode.

Above, I was using the watch to record times at my son’s cross-country meet.  Again, it was a bit disappointing that the time only displayed in minutes and seconds and not fractions of a second.

Pressing the upper right button gain puts the PowerWatch into Watch Settings mode.  This mode has several functions, but its main one is setting up pairing the watch with a smartphone, which requires downloading the free PowerWatch app from either the Apple App Store for iPhones or Google Play for Android phones.  It should be noted that the app is necessary for initial setup and doesn’t really require the app after that, but some of the watch’s functionality will be limited.

The PowerWatch app is fairly basic, with its main function being to facilitate pairing of your PowerWatch with your smartphone.  I was able to pair my iPhone 6 Plus with the PowerWatch X easily by following the prompts.  Let’s walk through a few things that you can do with the app.  First, you can select your watch under the “My Device” section.  From there, the first thing you can do is select Watch Faces; however, there is currently only one watch face, the default, so that isn’t useful until Matrix makes some additional watch faces available.  Notifications can also be controlled via the app, though this is somewhat limited: you can only turn Notifications on/off, and only for Calls, Messages, Alarms, and Activity Goals.  I had some issue with the Notifications.  I was receiving them when I first set up the watch, I was receiving them, but shortly after that, they spontaneously stopped.  I had to reset the way ch to get them working again, but the watch stopped vibrating when I received them, where previously it had vibrated slightly with every Notification.  This brings me to probably the most curious and irritating “feature” of this watch/app combo: you actually have to use the app to set an alarm, it can’t be done on the PowerWatch X itself!  Talk about missing a very basic watch feature.  This is enough to make me almost call it an “un-smart.”  Finally, you can update the Firmware from inside this “My Device” section.  Backing out to the “My Profile” section under “Settings,” the app also lets you edit Activity Goals (Steps, Calories, and Distance), Units, Language, and Password.   The app’s Dashboard screen shows Distance, Sleep time and Calories burned for that day and lets you scroll to past days.  Also note that the watch cannot be connected to any type of external Bluetooth biometric sensors (e.g. heart rate sensor), nor can it control music apps, or import fitness data into other fitness apps or to a computer.

The single accessory that is included with the PowerWatch X is an external charging base, as shown above left.  It uses a standard micro USB cable, which is not included.  I found this base to be a bit of an odd accessory to include, considering that the watch is supposed to charge with your body heat and never need charging otherwise, but I suppose if you for some reason you don’t wear the watch every day, you may need this.  In fact, after a week of inactivity, PowerWatch X will enter Power Save mode and turn off the screen.  If fully charged, the watch’s setting will be saved for one year.  In any case, as seen above right, when the watch is resting on the base, it automatically illuminates the PowerWatch X’s backlight, and a small red LED on the base illuminates.  The backlight can also be activated by pushing the top right “Mode” button for 2 seconds.   However, because of the origination of the light from only the side, I found it a bit difficult to read the display with the backlight on, even in completely dark conditions.

I wore the Matrix PowerWatch X for several days continuously, including during various types of exercise.  One very frustrating thing was that, during any activity, the watch’s screen would blank out and display the above “MATRIX INDUSTRIES” logo—and it would stay this way for long stretches of time, preventing me from reading the information that was supposed to be displayed in whatever mode it was in at the time, like Running Mode or Stop Watch model.  At first I thought that this might have been due to the watch attempting to conserve power because it was in a depleted state, but it even exhibited this behavior after having charged it on the base all night.  The PowerWatch X’s FAQ page states that the PowerWatch X will go to screensaver mode after 45 minutes of inactivity, but I found that it went into screensaver in a lot shorter time.

What I like

• Never needs charging–thermoelectric generator is powered by the wearer’s body heat!
• Looks tough—very spec ops/ninja style

What needs to be improved

• On-board and app functionality is pretty basic and limited for a “smartwatch”
• Goes into “screensaver” right in the middle of activities
• Notifications system has some pretty serious issues

Final thoughts

The Matrix PowerWatch X was a mixed bag for me.  While I was very impressed with its thermoelectric generator technology, which generates energy to power the watch’s battery through harvesting the heat transferred between cool ambient air and the wearer’s warmer skin, that was about the extent of what I was impressed with.  Its actual functions are very basic, and almost not worthy to be called a “smart” watch.  While I think Matrix has the start of something really great here with a bodyheat-powered watch that never needs charging (and looks way cool), I think they have a bit of ways to go with the watch’s functionality, which I think they can likely continue to improve with further watch firmware and app updates.  For a retail price of $279.00, to me it may be a bit overpriced, but it is still really unique and cool gadget and worth a look.

Price: $279.00
