Several smartwatches including the TicWatch Pro 3 Ultra have been leaked from Eden Hamilton's blog

There has been some speculation about the TicWatch Pro 3 Ultra appearing on the internet, and it appears that two more TicWatch GTH devices are on their way.

On the r/WearOS message board, images of the Pro 3 Ultra's packaging, which includes a list of the device's key specifications, have been leaked by unidentified users.

It appears that the TicWatch Pro 3 is only a minor improvement over the previous model, as it is powered by the same Snapdragon Wear 4100 engine and boasts the same three-day battery life as the previous model.

Despite this, it still has the longest conventional battery life of any Wear OS device, thanks to the dual layer display, which automatically switches to a monochrome LCD display  when the full AMOLED isn't being utilized.

We also expect the TicWatch Pro 3 Ultra to eventually run Wear OS 3.0, just as the regular Pro 3 will do in the not-too-distant future, as well.

There are new heart characteristics and Afib as well.
In terms of visual differences, the most noticeable difference between the box shot and actual product is that TicWatch Pro 3 Ultra promises to have afib detection – although it's unclear whether this is accomplished through ECG or another technique.

However, XDA Developers has been digging through the APK of the Mobvoi app's Version 4.3.0 and has discovered references to new heart health capabilities that have been added.

A reference to TruHR has been discovered, which suggests that it is a method of afib detection that makes use of an optical heart rate sensor, according to the information uncovered. It's possible that this will be extended to other new devices as well, such as the new TicWatch GTH+ and GTH Pro, which were discovered within the code as being compatible.

Aside from these features, the XDA Developers community has discovered mention of additional arterial age features, as well as metrics that demonstrate how much stress is placed on the heart as a result of arterial hardening. It appears that Mobvoi intends to place a significant bet on heart health insights with its next generation of gadgets, as evidenced by this statement.

With the TicWatch Pro Ultra, it appears to include a compass in addition to GPS, military-grade 810G ruggedness, and 20 different fitness modes, all of which are noteworthy.

Though, in terms of hardware, it appears to be a transitional upgrade, the addition of new health-related features has certainly piqued our interest. The TicWatch Pro 3 Ultra – or any of the other new GTH gadgets – will not be available until further notice, but we'll keep an eye out for any new developments.
