Looks like new info has leaked about another Amazfit smartwatch-the T-Rex 3 Pro now rumored to come in a larger 51mm case. The device appeared in an unboxing video posted by one of the brand’s ambassadors. Interestingly, the watch’s design matches earlier leaked images that were previously linked to a different rumored model-the Amazfit T-Rex Ultra 2.
The new Amazfit T-Rex 3 Pro 51mm made an appearance in a recent YouTube clip shared by HYROX athlete Hunter McIntyre. In the brief unboxing segment, he showcases the watch, referring to it as the “TRX Pro 51 mm.” This likely signals a new, largest version of the T-Rex 3 Pro family, adding to the existing 44mm and 48mm sizes. Compared side-by-side with the 48mm model, the size difference is clearly noticeable.
A quick look at the two versions reveals several design tweaks. The new model features thinner bezels at the top and bottom of the display, with four small notches next to the buttons. Button labels like Select and Up have moved from the bezel to the inner ring of the watch face. The red dial markers are gone, giving it a more minimalist and refined look. The video also mentions a built-in flashlight-a feature that’s carried over from previous T-Rex 3 Pro models. Beyond that, specific differences from past versions remain unclear.
It’s worth noting that the watch in this video closely resembles images of another device that had surfaced in leaks but were later taken down. Those images were initially attributed to the Amazfit T-Rex Ultra 2. Whether these are two distinct models or if earlier rumors about the Ultra 2 actually referred to this new 51mm T-Rex 3 Pro is still up in the air.
The release date for the Amazfit T-Rex 3 Pro 51mm remains unknown. For context, the 44mm and 48mm versions currently retail for around $400.
