I have had the Apple Watch Ultra 3 for more than a month now. Here are some impressions. Battery life is as expected, and I need to charge the watch at least every other day. Note: I do not disable functions to save battery life. If I can charge my IPhone every other day I can charge my watch at the same interval without it being an issue. Charging is extremely fast by the way.
The watch and Milanese Loop are made exceptionally well. I have purchased custom watch straps for the Ultra 3 to mix up the look. I would also classify the watch as rugged as I have knocked it several times into objects without the watch getting scratched or dinged.
The screen is bright and large enough for large fingers to use small screen shortcuts. I can make and receive calls and messages. I do wish that a dedicated browser could be developed and loaded directly on the watch so I can browse from the watch. The screen is large enough for it to make sense to have it.
Overall, this is a great watch, and I will purchase again probably in a few years with another more advanced version is released.
