The Samsung Galaxy Watch Ultra is a 47mm smartwatch built in a titanium case with sapphire crystal over the display. The 1.5-inch AMOLED screen reaches 3,000 nits, so you can read it in direct sun without cupping a hand over your wrist. A 590mAh battery lasts around three days in normal use. Dual-frequency GPS handles location tracking, which is more accurate in cities and under tree cover than the single-frequency kind. This is the blue model with Bluetooth and cellular.

The titanium case takes 10ATM of water pressure, which is enough for ocean swimming rather than just a shower. Samsung tested the watch to 9,000 meters of altitude and heat up to 55 degrees Celsius. Sapphire crystal over the screen resists the scratches you pick up scraping a wrist against rock or a bike frame. The watch carries IP68 and MIL-STD-810H ratings on top of that.
Daily usage normally results in a three-day battery life when fully charged. However, the Ultra’s Power Saving Mode can extend that to 100 hours. If you have GPS tracking enabled with exercise power saving active, this will give you approximately 60 hours of continuous tracking. That should be sufficient for multiple days of backpacking or running an ultramarathon and never needing to pack a battery charger.
