Amazfit is expanding its smartwatch lineup with another model that is not entirely new. However, the brand probably tries to convince more customers with a more compact variant of the T-Rex 3 Pro.

Amazfit is about to introduce a new version of the T-Rex 3 Pro. Specifically, the smartwatch will soon be available in another model, more specifically a 44mm version. This is slightly smaller than the regular Amazfit T-Rex 3 Pro, which measures 48mm. The wearable will be released in China on October 25, but there are no specific details on a global launch. That said, we would expect an international launch rather sooner than later.
Amazfit smartwatch gets more elegant
Anyhow, Amazfit already presented the 44mm version of the T-Rex 3 Pro alongside the larger version. This one is quite a bit smaller, which also reduces the screen size from 1.5 to 1.32 inches. In the teaser image that’s been shared on Reddit, the T-Rex 3 Pro 44m appears in a gold color. This more compact smartwatch probably targets people with slimmer wrists. However, it’s still not a small smartwatch, as the design looks quite rugged. There are no visible screws, but the rectangular buttons arguably make the watch look more robust.
No missing features on the 44mm T-Rex 3 Pro
The 44mm versions has the same feature set and will be water-resistant up to 10 ATM. It comes with a microphone, a speaker and a 3,000-nit display. Additionally, the smaller Amazfit T-Rex 3 Pro has a battery life of up to 17 days, which is 8 days shorter compared to the 48mm SKU, which is available from $399 on Amazon.

I have been active as a journalist for over 10 years, most of it in the field of technology. I worked for Tom’s Hardware and ComputerBase, among others, and have been working for Notebookcheck since 2017. My current focus is particularly on mini PCs and single-board computers such as the Raspberry Pi – so in other words, compact systems with a lot of potential. In addition, I have a soft spot for all kinds of wearables, especially smartwatches. My main profession is as a laboratory engineer, which is why neither scientific contexts nor the interpretation of complex measurements are foreign to me.

My fascination for technology goes back a long way to the Pentium II era. Modding, overclocking and treasuring computer hardware has since become an integral part of my life. As a student, I further developed a keen interest in mobile technologies that can make the stressful college life so much easier. After I fell in love with the creation of digital content while working in a marketing position, I now scour the web to bring you the most exciting topics in the world of tech. Outside the office, I’m particularly passionate about motorsports and mountain biking.
