Design
The device is dustproof and water-resistant. Water-resistant devices can resist the penetration of water, such as powerful water jets, but not being submerged into water.
Resistance to sweat makes it ideal for use while doing sports.
Damage-resistant glass (such as Corning Gorilla Glass or Asahi Dragontrail Glass) is thin, lightweight, and can withstand high levels of force.
The ATM rating indicates how much water pressure a device can withstand. 3 ATM is one of the lowest ratings and means that the device can only withstand splashes of water, whereas 20 ATM is one of the highest ratings and means that the device can be used for snorkeling and water sports.
The size of the screen (measured diagonally).
Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.
The type of technology used in the display.
The watch band is removable and can be replaced by any standard watch band of the correct size, allowing you to customise it to your liking.
You can operate the device easily, by pressing the screen with your fingers.
Sensors
GPS enables global positioning, useful in map, geo-tagging or navigation apps.
A heart rate monitor can help show your fitness levels, enabling you to calculate a suitable intensity of exercise.
Your blood oxygen level is a measurement how much oxygen is reaching your muscles. It is important because low levels mean that you will become easily fatigued during exercise. The more exercise you do, the better your blood oxygen levels will become.
This measures barometric air pressure. It can predict weather changes, for example a sudden drop in air pressure could mean a storm is coming. When calibrated correctly it can be used to determine altitude, which helps GPS devices to lock on quicker and with greater accuracy.
An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.
A compass is useful for gaming, maps, and navigation software.
With a temperature sensor you can monitor changes in temperature to measure your exertion levels and avoid hyperthermia.
A cadence sensor measures the number of pedal revolutions per minute when you are cycling. It enables you to monitor how fast you are pedaling.
A gyroscope is a sensor that tracks the orientation of a device, more specifically by measuring the angular rotational velocity. Initially, they were built using a spinning rotor to detect changes in orientation, like twisting or rotation.
Activity tracking
With a route tracker you can add your route onto a map. It is helpful if you plan to do the same route again, or want to share it with your community.
It tracks how far you travel.
Measuring pace shows how much time it takes to travel one kilometer or one mile. For example, in running, a 4 minute kilometer would be a very good pace.
This feature enables you to track your route and reverse it in order to guide you back to where you began your journey.
It can track your sleep, such as how long you sleep for and the quality.
A multi-sport mode allows you to easily switch between tracking different sports such as running, cycling, and swimming. This feature is ideal for those who need to change quickly between various activities (e.g., triathletes).
The device automatically detects when you start an activity such as jogging, saving you from entering it manually at a later time.
It can detect changes in elevation, such as when you are climbing stairs.
It tracks how many steps you take throughout the day, allowing you to see how active you have been.
Connectivity
It is compatible with a range of iOS devices such as iPhones, iPads and the iPod Touch.
It is compatible with a range of Android devices such as smartphones and tablets.
The device can connect to Wi-Fi.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
Devices that use cellular technology can connect to mobile networks. Cellular networks have much wider signal coverage than Wi-Fi.
ANT+ is a wireless protocol similar to Bluetooth Smart, and is very power efficient. It is mainly used for fitness monitoring devices such as heart rate monitors and cadence sensors to connect to other devices (e.g., sports watches, smartphones, and cycling computers).

Features
Heart rate variability (HRV) tracking measures fluctuations in the time between heart beats. These fluctuations can be an indication of health conditions (such as heart conditions or mental health issues). Note: This feature may not be available in all markets.
VO2 max capacity is a measurement of the amount of oxygen your body can use during physical exercise. A high VO2 max capacity indicates good fitness levels.
This measurement is your heart rate per minute when you're at rest, such as when you're relaxed, sitting, or lying down. For adults, this is typically between 60–100.
It can notify you when your resting heart rate is above or below the normal range.
This is based on various information, such as your previous workout, sleep quality, and stress levels. Taking everything into account, it will give you an idea of whether your body is ready for another workout or if you should focus on recovery.

I'm using my T Rex 2 for 2 years and I'm definitely satisfied with it. The battery lasts forever and recharge fully in less than an hour. The design shows the toughness and resistance of the G-shocks, the band is comfortable, the app show everything you need, and it resists to salt water. It have the trackback option and yes, you can upload kml maps in it (but all tech sites insists that ir can't). It have a password when you remove it from you wrist, but the bad thing about it is that eventually the password came back even in your wrist. Other bad thing is that I can't buy anything in the store. I've sent a lot of emails to the support but I didn't have and answer. But, in general, it's a very good smartwatch, with all you'll need indoor or outdoor.

Up to today, I've had it for 4 months, and the feature I like most is the track back for my job. I work in mining, and I'm in areas where there is no signal, and the GPS does its job excellently. Everything else performs its function well. For the price, it's great. I'm waiting for the Zepp OS 2.0 version this August 2023... I see it says it has body temperature measurement but it doesn't, hoping this is corrected in the comparisons.

Ultra é uma evolução, mas não justifica o preço.

O t rex representa uma boa evolução, porém não justifica o preço cobrado em comparação com o t rex 2, que hoje pode ser comprado por aproximadamente 40% do valor do t rex ultra. As diferenças mais expressivas são o acabamento em titânio, maior detalhamento dos mapas e a memória de 3gb para músicas. As outras mudanças são todas sutis e não representam exatamente um avanço.
