Most smartwatches are just an addition to a smartphone. A children’s watch without a parent’s smartphone is also useless, but with it it turns into a high-tech and non-irritating beacon, suitable for use in any conditions. Before us is the orange Ginzzu GZ-501 watch and the blue Ginzzu GZ-503, a little more powerful. Is this a worthy gift for a child or just another beautiful trinket?

At first glance, the devices are very similar. For example, both models are available in blue (the 501 also comes in orange), both have a color screen and buttons… But upon closer inspection, they are quite different.

The younger model is equipped with a non-removable strap, and there are more keys on its body, since the screen is not touch-sensitive. On the right side there are power and SOS buttons, on the left – a quick call to parents with Mom and Dad engraving. The micro SIM card is inserted from the back, the slot is covered with a plastic cover without a silicone gasket. Next to it there is a sensor for removing it from your hand and contacts for recharging.

The GZ-503 watch has a removable strap, although there is no particular point in this solution. There are only two buttons – power and emergency call, plus there is a multifunction key under the touch display. Both models are protected from moisture and dust according to the IP55 standard.

The watch is intended for children and looks very appropriate on a child’s wrist (although it seems a little heavy). They are quite noticeable, so they are difficult to lose, and the strap holds tightly – it will survive more than one active change at school.

The buttons on the case are small, but they are very convenient to press.

The watches are equipped with small color screens with low resolution. Since nothing supernatural is required from such gadgets, these displays are quite sufficient. The younger model has a non-touch screen with a diagonal of 0.98 inches, while the older model has a touch screen with a diagonal of 1.54 inches. Scrolling through the menu and moving through its items is comfortable for both adults and children – the size of the finger does not matter, and no special dexterity is required.

The device interface is more than simple. At the top of the screen there are indicators for the strength of the network signal, alarm clock, voice messages, GPS, Wi-Fi, data transfer via GPRS, the presence of a watch on the wrist, and battery charge. Below is the date and time, at the very bottom (if necessary) is the step counter and encouragement hearts from parents.

The 501 has slightly fewer features. It is possible to record up to 10 numbers in memory, set an alarm, turn on the pedometer (and calories are counted with it), send a voice message to your child (or call), order a call back to secretly listen to what is happening around the child, send an emergency message from the watch to trusted numbers, find a watch, and also create geofences within which the person wearing the gadget can move. The older model also has one game (solving mathematical problems) and sleep quality control. True, it sometimes counts sleep, sometimes it doesn’t – you shouldn’t rely on its readings, this function turned out to be just a pleasant addition to other counters. The pedometer is quite accurate; the discrepancy with a wrist fitness bracelet is about 10-15%.

To remotely control the clock, you need to install the Setracker 3 application on the parent smartphone (suitable for Android 4.4.2, iOS 7.0 and higher). You should create an account in it, and then scan or manually enter the registration code of the watch and come up with a name for it. This is where contact numbers (including emergency numbers) are set, tracking of a child via GPS and LBS (base stations), drawing of his routes, setting geofences (with an alert if the child goes outside the limits), searching for watches and a signal about removal from hand are available. or emergency situation, as well as statistics of steps, calories and sleep.

Routes are displayed on the map in straight lines, taking into account, for example, transfers to the metro or car. This is not a very convenient option (obviously it needs some work), but you can get an idea of ​​where your child has been. In addition, it is possible to track its exact location at any time.

The application interface is quite simple and clear, there are no glitches.

Hours in operation

Most of the watch’s capabilities are available only from the parents’ smartphone. Children can make calls, receive messages, “friend” watches (in the 503 model this is simply choosing a similar watch nearby as a “friend”), play (in the 503 model) – and that’s it. Since it is necessary for the child to always be in touch, the watch cannot be turned off after synchronization with the smartphone (this can only be done from the parents’ smartphone) – the right move.

Since the software in the watch is more than simple, there is nothing to slow down or freeze, the gadgets worked well during the test period.

By the way, both models have speakerphone only, so you shouldn’t have lengthy discussions about the quality of school lunches and grades received – it’s inconvenient.

Wireless interfaces

An important point: the watch transmits voice and data in 2G mode, which is why not every SIM card is suitable for communication (and not every tariff – Tele2 subscribers will understand). This is clearly stated in the instructions. The 501 model uses micro-SIM, the 503 uses nano-SIM. After installing the SIM card, you need to reboot the watch.

The call quality is quite decent, the child can be heard well. You can make calls in both directions.

The watch transmits location data at set intervals (from a minute to an hour) with high accuracy, and you can also get location data on demand. Simply put, parents will always know where the owner of the watch is – at school or in a neighboring house (up to the entrance). No failures in the operation of the main function were noticed; you can check it at any time.

Autonomous operation

Despite the fact that the batteries of the devices are almost twice as different in capacity, their operating time without recharging is almost the same: from the morning of the first day to the evening of the second with synchronization once every 10 minutes and four to five calls. This is quite enough, plus the child develops the habit of charging the gadget in the evening. The time to fully charge the batteries is from 1.5 to 2 hours. Conveniently, if the battery charge is low, the watch will notify parents of this fact.


The Ginzzu GZ-501 and GZ-503 watches are useful devices that are allowed even in schools where smartphones are not allowed (and rightly so – there is no point in playing during recess). The child is always connected, you can track his movements, and in extreme cases he will be able to call an emergency number with the press of one button. In addition, the hand-held sensor and the inability to turn off the watch will prevent you from losing contact. In a word, for schoolchildren from big cities (or small but unsafe ones), such devices are quite a useful thing.


  • convenient control;
  • optimal set of functions;
  • good autonomy.


  • quite large sizes.
