Samsung has not only brought us foldables. The Korean company has taken advantage of Unpacked to renew its range of smart watches which, as tradition dictates, consists of two devices: the Ultra model and the standard model which, again, as tradition dictates, this year skips the Classic version (and its fantastic rotating bezel).
We have, therefore, two new smartwatches that seek to win the gold of “best watch with Wear OS.” The most striking change is found in the Ultra, which greatly increases the level of its battery and brightness, but otherwise both watches share many of the functions and specifications.

The peculiarities of the Watch Ultra2

Samsung Galaxy Watch Ultra2 | Image: Xataka
He Watch Ultra2 It is the watch focused on the most athletic and, why not say it, those looking for a powerful watch that offers good autonomy. It is only available in a single 47 millimeter version, so yes, it is a big watch not suitable for small wrists. The frame is made of aluminum and is somewhat thinner than the previous model, specifically 12%.
As a sports/adventure watch that it is, it has all kinds of certifications and resistances to withstand the elements of, for example, water. Samsung boasts of offering resistance IP69K10 ATM (equivalent to 100 meters depth) and EN 13319. It is obvious that he feels good in the water and, in fact, it has a mode dedicated to diving that measures immersion time, water temperature, speed of ascent and descent, etc., developed together with Mares.

Coming out of the sea, the device has a feature called “Mountain Run” that offers information on altitude and terrain impact, and offers real-time hydration recommendations through Nutrition Alert. Basically the clock estimates sweat loss in relation to body weight and tells us when we need to drink water.
Last but not least, it has a screen with 5,000 nits of brightness (a completely absurd figure that, it must be said, we will take advantage of on very rare occasions) and 800 mAh battery. This change is notable compared to the previous generation, which had 590 mAh, and the reason, although Samsung does not mention it explicitly, seems obvious: silicon carbon batteryfinally.
A review of Watch9

He Galaxy Watch9 It is a watch more focused on everyday life. Although, as we will see soon, it offers the same sensors as its Ultra brother, this watch has a more casual, more lifestyle character. It is, without a doubt, more focused on keeping track of our lifestyle habits, sleep and exercise, as well as serving as a productivity assistant through notifications, calls and apps.
This model can be obtained in two versions: 40 and 44 millimeters. One is smaller, one is bigger. That obviously has a noticeable impact on the watch’s battery. While both do exactly the same thing, the 44-millimeter one will offer greater autonomy. Both have a frame made of aluminum and that “padded” design that the Galaxy Watch8.

The screen does not reach the 5,000 nits of the Ultra2, but it does amount to 3,000 nitsa much more reasonable figure that, in any case, will only be activated in fairly extreme lighting conditions. As far as stamina goes, it’s pretty tough, but not as tough as its older brother. It does not have EN 13319 certification, nor IP69K nor does it reach 10 ATM, so, although it can withstand water, it is not designed for diving.
What they share

Samsung Galaxy Watch9 and Ultra2 | Image: Xataka
Everything else, really. Both models incorporate the processor Snadragon Wear Elite (codename SDW6100) next to 2 gigabytes of RAM and enough storage for, really, everything you can ask for from a watch. The operating system is Wear OSso it is possible to access Google Play, Google Gemini and the entire catalog of third-party apps that we already know.
The sensor is capable of measuring heart rate, blood oxygen level, sleep and skin temperature. Nothing new, except for the sleep monitoring function (only for Galaxy phones), cardiovascular health functions, fitness index and hearing risk alerts. The idea of the watch is to be attentive to both our body and the environment, warn us and allow us to take action, all powered by AI, as it could not be otherwise.
Needless to say, both models allow you to receive and respond to notifications and calls, access the calendar, etc. They are watches with Wear OS, so the capabilities are varied and abundant.
