The smart watch market, like that of bracelets, managed to anchor within the bubble years ago ambitious products. Every year the leaders of the sector present models aimed at controlling health, albeit with a sports band. Next, the top six teams which are available in the country.
The sale of smartwatches, according to the company Counterpoint Researchposted 13% year-over-year growth, reaching shipments of 33.7 million units in the first quarter of 2022.
Within this category, Apple maintains a solid lead – its stake is 36% – and it has increased by 14% year over year. And while Samsung has a 10.1% share, its shipments have reached 46% compared to 2021. While Xiaomi has achieved a 69% increase and is beating its shipments record every quarter.
The six models that make up this selection are: Apple Watch Series 7, Galaxy Watch4, Garmin Venu 2 Plus, Huawei Watch Fit, Xiaomi Watch S1 GL and Amazfit T-Rex.
Apple Watch Series 7
Apple Watch Series 7. Trim the bezels to get a larger screen surface. From $ 75,000.
Screens, while tiny, require contrast and sharpness to do this clearly read numbers and dates. While some are betting on AMOLED panels, there are also those who are jumping on the LCD wave.
AMOLED, with lower power consumption, offers greater brightness and contrast, allowing for the design of thinner and lighter equipment that takes advantage of the entire front of the screen. The LCD is cheaper to assemble and its lifespan is longer, compared to the degradation that AMOLEDs undergo. It also offers a smoother tone when the viewing angle is shifted.
The differential of the 7 Series compared to its predecessors is the reduction of edges, which represents a 20% gain in its viewing area, according to Apple. The expansion of this panel is also completed by a modification of the front glass, which now has a thicker flat base which, in theory, makes it more resistant to bumps and scratches.
In addition, it has LTPO technology – which minimizes the energy impact, being able to dynamically vary the refresh rate – which allows it to increase the brightness of the Always-on mode up to 500 nits.
The charging system maintains its magnetic induction, while the arrival of the USB-C connector (instead of USB-A) does not improve autonomy, but completes the cycle in 50 minutes with Apple’s 20W module. From 75,000 pesos, depending on the strap.
Samsung Galaxy Watch 4
Galaxy Watch 4. This version has a digital bezel. They are 40 mm. $ 45,999
Watches, like any electronic device with the label of intelligentin addition to hardware, supervision of a software that takes care of regulating all processes inside and make the colored numbers more pleasing to the eye.
To support the Fitbit acquisition, Google, which had lost its way on this smart road, decided to redirect its gear by joining forces with Samsung. The result of this union is Wear, which recovers the best of Tizen and combines it with Wear OS.
The bet for the future is that Samsung, in collaboration with Fitbit, will be able to elevate Wear and give some surprises in terms of hardware, to obtain more competitive equipment that takes advantage of its link with Android, in the same way that Apple Watch does this with iOS.
The case is in stainless steel, the glass is signed by Gorilla Glass Victus and in the lower part the plastic coexists with the glass to protect the sensors. Its rotating bezel inherits the spirit of sports watches. To honor its premium status, it includes stereo speakers, a microphone for speaking to the assistant, and a wide variety of monitoring sensors.
It is available in different sizes and colors. The most accessible in 44 mm (43,999 pesos) and 40 mm (45.999 pesos) with a touch frame that controls the interface by touching the edge of the screen. And the so-called Classic, in 42 mm (54,999 pesos) and 46 mm (69,999 pesos) with rotating bezel and stainless steel finish.
Garmin Venu 2 Plus
Garmin Venu 2 Plus. High precision watch, ideal for extreme sports. $ 92,999.
These smartwatches can be essential for people suffering from chronic conditions such as asthma, heart disease and obstructive lung disease. The figures can be collected during the day or in the hours of sleep.
They depend on proper strap attachment, blood perfusion, extreme temperatures, or whether the body was at rest or in motion to get a reliable measurement.
The Venu 2 Plus focuses on well-being with a range of features including: heart rate, advanced sleep quality monitoring with scores and information, breathing activity, pulse oximeter and stress measurement.
Plus, add 25 built-in GPS tools for indoor sports like walking, high intensity interval training, cycling, swimming, yoga, rock climbing, hiking and advanced strength training with muscle map charts.
It comes with an AMOLED display, with a 43mm case, a stainless steel bezel and a 20mm quick release silicone strap. The battery, under ideal conditions, lasts nine days. It costs 92,999 pesos.
Xiaomi Watch S1GL
Xiaomi Watch S1 GL. For the measurements it uses multi-channel biosensors of the PPG type. $ 75,899.
The sensors that record the impulses adopt varies from 30 to 120 beats per minute, so the measurements are short but constant. This test involves a high energy expenditure, so some infrared lights alternate with LEDs to reduce consumption.
In this sense, photoplethysmography (PPG) provides the heart rate value by recording and analyzing a signal of optical origin. It is obtained from a vascular duct and is expressed by the change in blood volume resulting from the pumping of the heart.
Through a combination of algorithms and hardware, the Watch S1 GL uses PPG-type multi-channel biosensors for 24-hour heart rate monitoring. The wrist sensor activates during high-intensity exercise and sends alerts when a certain limit is exceeded .
It has an AMOLED touchscreen with a resolution of 466 by 466 pixels, with 326 pixels per inch (dpi), ambient light sensor. They are 75,899 pesos.
Huawei Watch Fit
Huawei Watch Fit. AMOLED screen with a resolution of 456 by 280 pixels and approximately 326 dpi. $ 22,199.
As with other screens – smartphones or televisions – the highs resist the passage of time better as they integrate more innovative components, offer better connectivity and broader support in the form of updates.
In addition to their functions, the boxes of these quantifiers can adopt two geometric shapes, which are purely aesthetic. With a square format, like the Huawei or circular like the Galaxy Watch.
Unlike traditional Swiss watchmaking, technology makers have developed a niche somewhere between casual and sport. The result is very sophisticated devices, with a sober design and traditional materials, which incorporate different sensors and a lot of computing load.
The device mounts a 1.64-inch AMOLED panel with a resolution of 456 by 280 pixels, with approximately 326 dpi. Enough number to not see the pixels with the naked eye. It is compatible with more than 300 covers. Get up to 10 days of autonomy. Listed at 22,199 pesos.
Amazfit T-Rex
Amazfit T-Rex. It has 12 “military certifications” which guarantee its resistance. $ 25,530.
Beyond aesthetics and handling, there is also an audience that, without sacrificing elegance, wants more robust than average equipment, able to absorb shocks or falls.
The T-Rex boasts of twelve “military certifications” which allow it to withstand temperatures between 70ºC and -40ºC, 240 hours in humid environments and resistance to acids and alkalis. They also claim that it is water resistant up to 50 meters deep.
Unlike other watches that try to go unnoticed, this one stands out for its thickness and is noticeable when someone wears it. However, it only weighs 58 grams.
It comes with a 1.3-inch circular AMOLED panel with a resolution of 360 by 360 pixels, which, according to Amazfit, is protected by Gorilla Glass 3. They are 25,530 pesos.
