Samsung Galaxy Watch Ultra 2 leaks look sleek and real

Leaked renders of the Samsung Galaxy Watch Ultra 2 have surfaced just days before Samsung Galaxy Unpacked in London, according to Mashable. The images, shared by leaker Evan Blass, point to a sleeker design plus major upgrades: an 800mAh battery, IP69K resistance, a brighter 5,000-nit display, and a Snapdragon Wear Elite chip.

Key Takeaways

• Prolific leaker Evan Blass posted official-looking Samsung Galaxy Watch Ultra 2 renders on Substack ahead of Unpacked in London.
• The leak cites an 800mAh battery, up from the 590mAh cell in last year's model, plus a design said to be 12 percent thinner.
• Display peak brightness is listed at 5,000 nits, versus 3,000 nits on the previous watch, matching earlier "record-breakingly bright" claims.
• Other leaked details include an IP69K dust- and water-resistance rating and a Snapdragon Wear Elite chip.
• Mashable notes the claims largely line up with other recent leaks, with Unpacked set for July 22, 2026.

If you follow high-end wearables, this is the familiar pre-event scramble: Samsung's flagship smartwatch lineup is leaking hard again, and the Samsung Galaxy Watch Ultra story just got a lot more visual. For more then-and-now tech flashbacks, browse our Nostalgia: Then & Now coverage.

What do the Samsung Galaxy Watch Ultra 2 leak renders show?

According to Mashable's report, the latest leak comes from Evan Blass, who shared several very official-looking renders of the new Samsung Galaxy Watch Ultra 2 on Substack. The timing is tight: the post landed just a couple of days before Samsung Galaxy Unpacked in London.

Those renders do more than tease a silhouette. Mashable says they show the device's appearance and include on-image text that showcases various specs. In other words, this is not a blurry spy shot from a factory floor. It is the kind of polished visual package that makes a product feel "more real than ever" before the keynote lights go up.

That pattern fits Samsung's usual pre-launch rhythm. Mashable notes that while Apple tends to keep a tight lid on specs and features, Samsung smartphones and watches typically leak widely ahead of their official launch—and this cycle is no exception.

How does the new Ultra compare with last year's watch?

The nostalgia hook here is simple: same Ultra ambition, bigger numbers. Last year's Galaxy Watch Ultra carried a 590mAh battery. The leaked Samsung Galaxy Watch Ultra 2 materials point to an 800mAh cell—a clear jump for anyone watching battery claims ahead of Unpacked.

Thickness is another then-versus-now talking point. The leak claims the new wearable is supposed to be 12 percent thinner. For a rugged, high-end sports watch, that is the kind of refinement that can change how the device feels on the wrist without abandoning the Ultra identity.

Brightness may be the flashiest delta. Peak display brightness is set at 5,000 nits in the leaked materials, up from 3,000 nits on the previous watch. Mashable notes that figure matches an earlier leak that called the new Galaxy Watch Ultra 2 display "record-breakingly bright"—useful outdoors when sunlight washes out lesser screens.

Durability language also steps up. The leaked specs include an IP69K dust- and water-resistance rating, underscoring the Ultra line's hardcore positioning rather than a casual fashion-watch reboot.

Which chip and other specs are rumored for the Ultra 2?

Beyond battery, brightness, and bulk, the leak claims the wearable will supposedly use the Snapdragon Wear Elite chip. Mashable adds that pretty much all of that lines up with other recent leaks, which strengthens confidence even though nothing is official until Samsung speaks.

Still, leaks are leaks. Specs on renders can be wrong, incomplete, or strategically floated. Treat the Snapdragon Wear Elite mention, the IP69K rating, and the battery jump as strongly suggested—not confirmed—until Unpacked puts them on stage.

What matters for readers right now is the shape of the story: Samsung appears to be iterating the Ultra formula with endurance, outdoor readability, and a slightly sleeker profile, rather than inventing an entirely new wearable category overnight.

When will Samsung confirm the Galaxy Watch Ultra 2?

Mashable's article said there were only about 48 hours left before Unpacked at the time of publication. The outlet also said it would attend Samsung Galaxy Unpacked in London on July 22 and planned a live blog plus updates on the latest announcements.

That calendar is why these renders landed with such force. When an event is days away, polished leaks do double duty: they set expectations for fans and give reviewers a checklist of claims to verify on launch day.

Until Samsung presents the Samsung Galaxy Watch Ultra 2 in London, the smartest read is cautious excitement. The leaked package—thinner body, larger battery, brighter panel, tougher resistance rating, and a new Wear chip—sketches a credible next chapter for the Ultra line. Confirmation, pricing, and software details still belong to the keynote.

For now, the sleek new wearable exists most vividly in Blass's renders and Mashable's write-up. Check back after July 22 for the official then-and-now verdict once the real hardware is on the wrist.
