Level with the Google Pixel Watch 4 45mm

The Google Pixel Watch 4 45mm and the Samsung Galaxy Watch Ultra 47mm score the same, so either is a safe pick. The Google Pixel Watch 4 45mm goes first because it does a little better with the review sites. The Samsung Galaxy Watch Ultra 47mm leaves owners a little happier.

About the Samsung Galaxy Watch Ultra

The Galaxy Watch Ultra has a 47.4 mm square-ish case about 12 mm thick, with a titanium frame, a sapphire crystal front and a 1.5-inch Super AMOLED display (480 x 480 pixels, up to 3,000 nits). It weighs about 60 g without a band. There is only one case size. Samsung's US page lists it in four titanium colors: blue, silver, gray and white.

Water resistance is 10 ATM (100 m) plus IP68, and the watch is MIL-STD-810H certified. Next to the touchscreen are three physical buttons, including a large Quick button for starting workouts. There is no digital crown. GPS is dual-band (L1 and L5), which reviewers found more accurate than earlier Galaxy Watches.

Inside is an Exynos W1000 chip, 2 GB of RAM and a 590 mAh battery. It runs Wear OS with Samsung's One UI Watch on top and has Bluetooth, Wi-Fi and NFC. LTE is optional and works on Verizon, AT&T and T-Mobile with a carrier plan. The Marine-style band fits wrists of roughly 145 to 205 mm around.

What owners report about the Samsung Galaxy Watch Ultra

We found little owner feedback on this exact model that we could open and read, so this section is short.

Reviewers who used the watch describe a bright display, a fast interface, and GPS and workout tracking that are better than on earlier Galaxy Watches. Opinions on the battery differ: one reviewer got about two days, another about a day and a half of moderate use. Both sit well below the 100-hour figure Samsung gives for its power saving mode. Reviewers also say the watch is very large and heavy, and one found the lack of a digital crown awkward. A retailer roundup lists a stock band that feels cheap (it can be swapped), slow charging and scuffs on the case, but it does not say whose experience that is.

Who the Samsung Galaxy Watch Ultra suits

Buy it if you use an Android phone, have a wrist big enough for a 47mm case, and want a watch that handles swimming, hiking and rough use. The dual-band GPS and the Quick workout button suit regular outdoor exercise, and the optional LTE lets you leave the phone at home.

Look elsewhere if you have an iPhone, since it will not pair. Small wrists will find it bulky: the Galaxy Watch 8 44mm and the Garmin Forerunner 165 are lighter. If you want a Wear OS watch with Google apps and Fitbit health tracking, the Google Pixel Watch 4 is the closer match. For a rugged watch with a battery that runs for many days, the Garmin Instinct 3 AMOLED 45mm lasts longer.

Questions about the Samsung Galaxy Watch Ultra

Is the Samsung Galaxy Watch Ultra waterproof?

It is water resistant, not waterproof. It has a 10 ATM (100 m) rating plus IP68, so it is built for swimming and showering, but not for high-pressure water sports.

Does the Samsung Galaxy Watch Ultra work with an iPhone?

No. It needs an Android phone running Android 11 or newer. Some health features also work best with a Samsung phone.

Is there a 2026 Samsung Galaxy Watch Ultra?

The Samsung US page we read lists the 2025 Galaxy Watch Ultra in 47mm, and we found no newer model on it. The 47mm size is the only one offered.

Does the Samsung Galaxy Watch Ultra 47mm have LTE?

LTE is optional. Samsung's US page lists support for Verizon, AT&T and T-Mobile, and it needs a carrier plan.

How long does the Samsung Galaxy Watch Ultra battery last?

Reviewers report about a day and a half to two days of normal use. Samsung gives up to 100 hours in Power Saving mode, which reviewers did not confirm.

How we score it

Every score here comes from our ranking model; no editor sets the order. Most of each score is what the review sites say: the scores their own reviews give each model, and whether their best-of lists name it. For this guide we read CNN Underscored, Reviewed, T3, TechRadar and The Verge. The rest is how happy owners are, held back where few owners have rated a product, and how new it is. Value for money earns its own badge rather than a higher place. We compared 19 models for this guide before settling on these ten.

Brands can't pay to be included or to move up. We last checked these picks in November 2026.
