Amazfit’s T-Rex 3 Pro line-up could get a new 51 mm variant
Another Amazfit smartwatch, the T-Rex 3 Pro 51 mm, appears to have been leaked. Shown in an unboxing video from one of the brand’s ambassadors, this could be the largest model in the current T-Rex series. However, the watch shown in the video matches leaked images that were attributed to another rumored model: the T-Rex Ultra 2.

A new Amazfit T-Rex 3 Pro 51 mm smartwatch appears to have leaked. This unreleased wearable was shown in a recent YouTube video created by one of Amazfit’s brand ambassadors.

In a short unboxing section of Hunter McIntyre’s latest YouTube video (below), the HYROX athlete shows a smartwatch which they refer to as the “TRX Pro 51 mm”. Presumably, this refers to a new 51 mm version of the T-Rex 3 Pro, which is currently offered in two smaller sizes: 44 mm and 48 mm. When McIntyre places this new watch next to the 48 mm variant, the increase in size is easy to appreciate.

The side-by-side comparison of the 48 mm and 51 mm versions of the T-Rex 3 Pro also demonstrates several design differences. For example, the bezel appears slimmer at the top and bottom of the watch face, and there are four notches next to the pushers. Button labels like ‘Select’ and ‘Up’ are moved from the bezel to an inner ring, and the red arrow markers are removed, for a cleaner look overall. In the video, McIntyre also mentions a flashlight, a tool which is included in the older versions of the T-Rex 3 Pro. Otherwise, it is unclear how this new model could differ from its predecessors.

It is worth noting that the Amazfit watch shown in this video has a similar design to another smartwatch shared in recently leaked images, which have since been deleted. These earlier pictures were attributed to a different rumored model, the Amazfit T-Rex Ultra 2. It is unclear whether there are two different wearables on the way, or if earlier rumors of a T-Rex Ultra 2 should, in fact, have been attributed to the T-Rex 3 Pro 51 mm.

It remains to be seen when the Amazfit T-Rex 3 Pro 51 mm smartwatch could be released. Both the 44 mm and 48 mm versions of the watch retail for $399.99 (Amazon); whether the larger size will also have this RRP is unclear.
