Launched last September, the Amazfit GTR 4 is a 46mm smartwatch with a 1.43-inch circular display. The Amazfit GTR Mini smartwatch is now available in the US, UK and EU for $120, £130 and €130. Currently about 952 renminbi). In India, it costs 11,000 Indian rupees (about 917 RMB).
Using a 42mm chassis, the GTR Mini is also thinner and lighter at 9.25mm and 24.6g, compared to the 12.4mm and 34g of the larger model. The watch supports a quick-detachable 20mm band (the included band is made of skin-friendly silicone).
The GTR Mini is equipped with a 1.28-inch AMOLED display with a 326ppi pixel density, which is the same clarity as a larger display. Both watches promise up to 14 days of battery life. The smaller model has a built-in 280mAh battery that takes several hours to charge.
The GTR Mini has almost the same functionality as the GTR 4. The watch’s built-in GPS receiver uses Amazfit’s patented circularly polarized antenna for enhanced signal reception. The watch supports a total of five global positioning systems (the larger model also supports dual-band positioning). With continuous GPS tracking, the battery lasts up to 25 hours.
The GTR Mini has more than 120 sports modes and is 5 ATM water resistant (50 meters) for wearing while swimming. Fitness data recorded by the watch can be shared with Google Fit and Apple Health, as well as apps such as Strava, Relive and Adidas Running.
For fitness tracking, the watch allows for 24/7 heart rate and SpO2 monitoring. The sensor is fast enough that the one-touch measurement feature can report its results in as little as 15 seconds. Sleep tracking detects light, deep and REM sleep and keeps an eye out for any breathing problems while you sleep. When users wake up, they receive (customizable) morning updates.
