In just five years, smartwatches have gone from a virtually useless accessory for viewing smartphone notifications to one of the most popular gadgets for health monitoring, navigation, and much more. smart watch price in pakistan We have collected for you the top most interesting functions that have appeared in smart watches in recent years.
Manufacturers:
Over time, smart watch manufacturers have shifted their focus to activity monitoring functions, assessing the user’s body condition, and interacting with a smartphone—the main smart device of our time. If suddenly you do not have time to follow the development of technology, we will remind you that manufacturers have introduced interesting things in recent years.
Blood oxygen monitoring function
Let’s face it: until 2020, no one knew what this parameter was and why it was so important. But after the outbreak of the COVID-19 pandemic, it turned out that it was the level of oxygen in the blood that could become the primary means of diagnosis: the normal level is 94-99%, if it falls below 90%, then lung function may be impaired, and possibly due to for the virus.
The first watch capable of calculating the approximate oxygen content in the blood was the Apple Watch Series 6. Since the function was extremely important during the pandemic, other manufacturers began to implement it en masse.
Determining blood sugar levels
A relevant (and long-awaited) feature for diabetics. Until now, in order to control sugar levels, you have to do tests that require puncturing the skin, and the ability to not only assess this level, but also monitor it constantly can make life radically easier.
So far, this option is implemented only in HUAWEI Watch 4 and Watch 4 Pro, but it may appear in the next generation of Apple Watch, as well as in products from other brands.
Emphasizers
HUAWEI emphasizes that the watch should not be perceived as a medical device: it does not measure the level accurately (unlike test strips), but only warns of a likely increase and recommends paying attention to it. For assessment, the method of molecular spectroscopy is used – in simple terms, illumination of an area of skin and analysis of reflected light. The
oxygen level in the blood is determined using the same principle.
Taking an ECG
The Apple Watch Series 4 was the first among smart wearable gadgets to learn how to take a cardiogram in 2018, but in Russia the function started working only in 2021, since its activation required permission from health authorities.
To measure an ECG, doctors usually attach several electrodes to a person. The watch uses only two: one already touches the wrist when the watch is put on – it is installed on the bottom panel of the watch – and the second one needs to be touched by a finger of the other hand.
For example:
Apple Watch Series 4 and newer, Huawei Watch GT3 Pro , and Samsung Galaxy Watch5 can take ECGs .
So, in the Samsung Galaxy Watch 5, a ring on the bottom panel is used as one electrode, and the second role is played by a button – you need to hold your finger on it during the measurement (both elements are highlighted in blue)

Of course, the accuracy of an ECG is not at all “medical”; in addition, manufacturers recommend carefully following the measurement rules, but the task of wearable devices is only to assess the heart rhythm and, if abnormalities are detected, advise you to consult a doctor. The last word always belongs to a person with a professional medical education
Skin temperature measurement
This function requires some comment. Imagine: you measure the temperature with a new watch and see on the screen, for example, 32 °C. How can this be? Is your watch not working correctly? Are you slowly cooling down? No, in fact, everything is correct: the watch can only measure skin temperature, and it is usually 3-6 °C lower than body temperature. For hands, 31−32 °C is a normal value.
Here again it is worth recalling that smart gadgets are designed only to warn you about abnormal deviations in body parameters. If for a long time the wrist temperature remained at 32 °C, and then began to increase by 5-6 °C, this is a cause for concern – the gadget let you know, and you decide for yourself how critical it is.
Separately,
it is worth noting that in the Apple Watch Series 8, the temperature sensor is used only to determine the periods of ovulation in women, at a certain stage of which there is an increase in temperature: it records only the norm and notifies about deviations from it, but the body or skin temperature itself using these hours cannot be measured.
Here are some models from the M.Video catalog that have the function of measuring skin temperature:
ESIM support
Another feature that “arrived” to us late. eSIM support allows the watch to be an independent communication device and not depend on a smartphone. The watch needs the Internet to install applications, maps, play music through the player and other tasks. Plus banal conversations, say, when you receive a call while jogging (you no longer need to take your smartphone with you), provided that you can connect a Bluetooth headset.
eSIM support is available, for example, in the HUAWEI Watch 3 – you can make calls from it directly, and also receive calls.
For the first time, access to LTE networks via eSIM appeared in the Apple Watch Series 3 in 2017, but since virtual SIM cards could not be issued in Russia for a long time, there was no point in the new option. The situation changed in 2020, and today all mobile operators are ready to issue a virtual SIM card. True, in the case of Apple gadgets, everything is still sad, since they require an electronic duplicate of the SIM card that is installed in the iPhone, and in our case one number cannot be installed on two SIM cards.
