Samsung has taken the veil off of the Samsung Galaxy Watch 7, but that wasn’t the only smartwatch announced at the company’s second Unpacked showcase of 2024. The brand new Samsung Galaxy Watch Ultra has a vastly different look when compared to the Watch 7, as well as a few significant upgrades to the formula.

Let’s take a look at the core differences between the Galaxy Watch 7 and Galaxy Watch Ultra to help you figure out which watch is the better fit (pun semi-intended.)

Galaxy Watch 7 vs Watch Ultra: What’s the difference?

The Galaxy Watch 7 and Watch Ultra share a lot of common ground. Both watches are powered by an Exynos W1000 SoC with 2GB of RAM and 32GB of storage. There’s the same software and many of the same workout features. Unlike Apple, Samsung equips the entire Galaxy Watch 7 series with L1+L5 GPS, making the Watch 7 one of the cheapest options to offer dual-frequency GPS. Of course, there are plenty of key differences. Let’s break down the biggest below:

  • Design.  The Watch 7 doesn’t shake up its design much when compared to its predecessor. The same can’t be said for the Ultra, which is quite a bit different from Samsung’s other watches. There’s a more square-ish case this time and there’s Grade 4 titanium onboard. It’s still a rounded display, but the end result is a very distinct look from the standard Watch 7 models.
  • Durability. The Galaxy Watch 7 is already a fairly durable watch thanks to its IP68 rating and 5ATM waterproofing, making it capable of surviving up to 50 meters deep for up to ten minutes. There’s also MIL-STD-810H certification. The Watch Ultra simply takes things a step further by switching to titanium as mentioned, as well as upgrading the waterproofing to 10ATM, which lets you dive up to 100 meters deep.
  • Improved brightness. The display used in the Ultra has the same specs as you’ll find on the 44mm Watch 7, with the exception of brightness. The Ultra can get up to 3,000 nits vs the 2,000 nits on the Watch 7.
    Extra workout and safety features. 
    The Watch 7 Ultra has all the same fitness and health features as the Watch 7 but adds a few small extras. There’s a multi-sports tile for tracking workouts that run through several courses, as well as the power to measure Functional Threshold Power when cycling. Finally, the Ultra has an 85dB emergency siren.
  • Size and weight. The Watch 7 is available in 40mm and 44mm versions that weigh 28.9g and 33.8g, respectively. The Ultra is 47mm and weighs quite a bit more at 60.5g.
  • Battery size. The Watch 7 has two different battery sizes, depending on what size of watch you pick up. The smaller model has a 300mAh battery, while the 44mm bumps up to a 425mAh battery. Both of these models have much smaller batteries when compared to the Watch 7 Ultra’s 590mAh capacity.
  • Pricing. The Watch 7 starts at $299.99, while the Watch Ultra is much more expensive at $649.99. Keep in mind the Watch Ultra doesn’t offer a Bluetooth-only model, so you will have LTE support here.
