Apple Watch Series 11 vs. Series 10: Are the Differences Enough to Justify Upgrading?

At first glance, the new Apple Watch Series 11 looks a lot like its previous-year model. We compare the specs to see what’s changed.

If you’re looking at getting an Apple Watch this holiday season, you have a tough choice: Should you buy the latest Apple Watch Series 11, or find a Series 10 that has most of the same features at a lower cost? Apple made incremental changes to its flagship smartwatch, while also introducing significant improvements to the Apple Watch Ultra 3 and Apple Watch SE 3.

There are still enough differences to make you look twice at moving up (especially if you’re coming from an older model). Let’s compare the models side by side and tease out the finer details.

Pricing the Apple Watch Series 11

The Series 11 has kept the same price as the Series 10. It starts at $399 for the model with an aluminum body or $699 for one made of titanium.

Add $30 for the larger 46mm case size in aluminum, or $50 for titanium. Opting for a model with a cellular radio that connects independently to networks adds $100. And if you choose a band made of something other than rubber or textile — a stainless steel link bracelet, for example — the price climbs further. Unfortunately, you can’t order just the watch case; you have to select a new band, even if it ends up in your drawer in favor of one you already own and prefer.

There’s also a titanium Apple Watch Hermès model available in silver titanium in both sizes that starts at $1,249.

Apple no longer sells the Series 10, since the Series 11 replaces it, but you can still find refurbished Series 10 models for less from Apple, and new models from other retailers while supplies last.

Apple Watch Series 11 vs. Series 10: Outward design

The Series 11 and Series 10 share the same case design and materials. The larger model measures 46mm tall by 39mm wide, while the smaller comes in at 42mm by 36mm. (Kudos to Apple for continuing to offer two sizes to accommodate people with different-sized wrists.) They’re also both 1mm slimmer than the Apple Watch models that came before, at 9.7mm.

Despite being mostly the same in dimensions, the Series 11 is slightly heavier than the Series 10. For example, the 46mm aluminum GPS Series 11 weighs 37.8 grams, up slightly from 36.4 grams for the Series 10. The 42mm versions come in at 30.3 grams and 30.0 grams, respectively.

For colors, the Series 11 adds a space gray aluminum option to go along with rose gold, silver and jet black. Both models are also available in titanium finishes of slate, gold and natural.

The physical controls are unchanged: the dial that Apple calls the Digital Crown and a side button (that Apple cleverly calls the “side button”). Only the Apple Watch Ultra includes a third physical control: the Action button.

Also noteworthy: The titanium Series 11 is made of 100% recycled titanium, up from 95% recycled material in the titanium Series 10. The display glass is made of 40% recycled glass in the Series 11; no amount is listed for the Series 10. And the battery in the Series 11 uses 100% recycled cobalt and 95% recycled lithium. (The Series 10 lists only 100% recycled cobalt.)

Series 11 vs. Series 10 screens

The screens on both the Series 11 and Series 10 watches have a wide-angle LTPO 3 OLED display. That means it’s easier to see the contents from an angle, and the always-on display refreshes once per second, allowing the seconds counter to move even when the watch is in inactive mode.

LTPO3 screens are also more power efficient. The screens reach up to 2,000 nits for clear visibility in sunlight and dim down to just 1 nit in darkness.

The key difference between the Series 11 and Series 10 screens lies in the glass covering. On the Series 11 aluminum models, Apple uses Ion-X glass, which it claims is twice as scratch-resistant as the glass on previous aluminum versions. The titanium Series 11 uses a sapphire crystal display.

Apple Watch processor and chips

Normally we’d highlight how the new processor improves on its predecessor, but for 2025 Apple stuck with the same S10 processor found in the Series 10. That also means the other chips remain the same, too: the W3 Apple Wireless chip, the second-generation Ultra Wideband chip (for precise Find My location tracking), a four-core Neural Engine and 64GB of storage.

Battery power: Series 11 vs. Series 10

Battery life is where the two models get really interesting. Apple doesn’t reveal how large the built-in lithium-ion battery is or its capacity, but it is claiming up to 24 hours for the Series 11 compared to 18 hours for the Series 10. In Low Power Mode, that’s up to 38 hours for the Series 11, up from 36 hours in the Series 10.

It’s not entirely clear where Apple squeezed an extra six hours of battery life out of what appears to be mostly identical hardware. Both phones use the same S10 processor, though there are likely software optimizations in WatchOS 26. CNET lead writer Vanessa Hand Orellana found that, at least initially, Apple may be undercounting the battery performance, writing in her review, “With notifications turned on (heavy Slack-ing and texting), at least one 30- to 45-minute outdoor workout a day, a full night of sleep tracking and some mild flashlight use, I’ve consistently managed to squeeze between 27 and 32 hours per charge.”

As for charging the watches, both the Series 11 and Series 10 can be charged up to 80% in about 30 minutes. Apple says that with a 20W power adapter, 15 minutes of fast charging provides up to 8 hours of regular use, while just five minutes is enough for eight hours of sleep tracking — thanks to the watch’s much lower power demands while you’re asleep. Apple’s comparison information for the Series 10 doesn’t list those last two metrics, but that seems more due to it being a marketing point last year versus a new capability in the Series 11.

Comparing the sensors of the Series 11 and Series 10

The Apple Watch’s sensors power health features that range from heart-rate monitoring to depth sensing to precise location tracking. That said…

They’re identical in the Series 11 and Series 10. No changes here.

Another change: Connectivity in the Series 11 and Series 10

One of the more notable changes in the cellular models of the Series 11 is support for 5G networks, specifically a power-efficient type called 5G Reduced Capacity (or 5G RedCap). That allows it to connect to both 5G and LTE networks without having to go through a connected iPhone, and the 5G speeds should be better. By comparison, the cellular Series 10 supports LTE and UMTS (3G).

Part of incorporating 5G into the Series 11 models is a redesigned cellular antenna and an algorithm that “simultaneously engages the two system antennas when needed, significantly increasing the signal strength,” according to Apple’s Series 11 press release. That algorithm is exclusive to the Series 11 and Apple Watch Ultra 3, per Apple.

Both Apple Watch models support Wi-Fi 4 (802.11n) at 2.5GHz and 5GHz speeds. (Apple’s comparison page only lists the speeds for the Series 11, but an Apple Watch Wi-Fi support page notes 5GHz has been supported since the Series 6 watches.)

Both watches talk to the iPhone and other peripherals using Bluetooth 5.3.

WatchOS 26 on the Apple Watch Series 11 and Series 10

The new features of WatchOS 26 come to both watch models, including hypertension notifications, Sleep Score and the Blood Oxygen app (making its reappearance in the US amid an ongoing legal dispute). Apple’s comparison page lists the new Wrist Flick gesture for the Series 11 but not the Series 10, but that must be a typo because I can confirm that it works on my Series 10 watch.

Washington’s major crypto bill stalls as SEC forges ahead

The SEC has proposed new rules to simplify crypto custody for advisers and funds, aiming to update outdated requirements and expand investment options. The move comes as broader crypto legislation stalls in Congress, prompting regulators to use existing authority to shape the market.

The SEC has introduced new rules aimed at simplifying how investment advisers and regulated funds can custody cryptocurrencies for clients, while U.S. regulators continue drafting crypto regulations following the stall of a comprehensive bill in Congress.

Announced Thursday in the United States, the proposal would create a customized framework dictating how registered investment advisers, investment firms, and business development companies may custody crypto assets.

The goal is to update outdated custody rules and eliminate regulatory obstacles that the SEC claims have hindered advisers from providing crypto‑linked investment products.

Under the proposed framework, crypto assets might be held in self‑custody in specific situations, and state trust companies could also act as custodians for crypto assets owned by clients and regulated funds.

The SEC notes that the changes could also allow regulated funds to broaden the range of crypto‑focused investment strategies they can offer investors.

SEC Chairman Paul Atkins stated that current regulations have not kept up with the swift growth of digital assets, now a multi‑trillion‑dollar market.

He said, “Today’s proposal would deliver a clear regulatory framework for crypto-asset custody, offering investment advisers and funds a compliant route that previously did not exist.”

The proposal arrives as U.S. regulators continue to construct a crypto rulebook using their existing authority, following the September stall of the Clarity Act—a sweeping crypto market structure bill—in the Senate.

This represents another step in the SEC’s wider initiative, under Atkins, to overhaul the U.S. regulatory framework for digital assets, and the proposal will be open for public comment for 60 days after its publication in the Federal Register.

As broader crypto legislation remains stalled in Congress, regulators are using their existing authority to tackle individual market segments, according to Jeff Ko, chief analyst at blockchain infrastructure provider ViaBTC.

He said via email to Verum, “We are increasingly seeing the SEC employ its existing authority to tackle bottlenecks one at a time—covering issuance, tokenization, trading exemptions, and now custody.”

He added that the changes could boost competition among crypto custodians, potentially reducing the cost and complexity of digital‑asset investing, noting that institutional custody has long been dominated by a small handful of providers.

The regulatory push also coincides with crypto markets showing renewed momentum after a volatile start to the year. Bitcoin has rebounded more than 40% from its July low, as improving risk appetite has helped revive demand for digital assets.

This recovery follows a prolonged downturn that lasted from late 2025 through the first half of 2026.

Passengers and crew foil co-pilot’s apparent attempt to crash FlyDubai flight to Israel

One of the pilots on a FlyDubai flight headed for Israel stabbed the second pilot, according to Israeli Prime Minister Benjamin Netanyahu.

On-duty flight crew and passengers managed to foil a pilot’s apparent attempt to crash a FlyDubai flight, after reports emerged of a fight in the cockpit.

The incident on flight FZ1073 from Dubai to Tel Aviv happened when a co-pilot stabbed a pilot, according to Israeli Prime Minister Benjamin Netanyahu, who praised the victim’s quick thinking.

“Despite being stabbed and seriously injured, he fought back, resisted, opened the cockpit door, and enabled passengers and crew to overpower the attacker — preventing a catastrophic mid-air disaster. He saved the lives of 174 people, including Israeli citizens and other nationals,” Netanyahu wrote in a post on X.

FZ1073 was diverted to the Tabuk airport in Saudi Arabia, the airline said, after being successfully secured and diverted by flight crew.

FlyDubai in a statement said that an “altercation” occurred on the flight deck of the plane, but did not mention a stabbing.

However, the airline added that the underlying reasons and motives for the clash is currently unknown, urging all parties to refrain from speculation.

The injured pilot was identified by Netanyahu as Indian national Smit Machchhar. No details have been released on the identity of the attacker, except that he was being interrogated by Saudi authorities.

The Indian embassy in Riyadh said on X that Machchhar is in a hospital in Tabuk, and is reported to be in stable condition.

The Israeli Prime Minister also identified the passenger who broke into the cockpit as Yaniv Hayun, calling him a “hero” and adding he deserved “a global medal of honor.”

Flight data from tracking site FlightRadar24 showed that the plane had experienced extreme altitude fluctuations before broadcasting a “general emergency” squawk code.

FZ1073 had dropped from over 14,000 feet in just 29 seconds, and FlightRadar24 also added that vertical speeds ranging from approximately -30,000 to +10,000 feet per minute were observed from the transponder data.

For context, vertical speeds during normal operations rarely exceed plus or minus 4,000 feet per minute, it added.

South Korean President Lee resists Alaska LNG project after Trump highlights Seoul’s involvement

South Korean President Lee Jae‑myung has conditioned his country’s participation in the Alaska LNG project on financial viability and legal compliance, pushing back against President Trump’s push for the $50‑billion venture while other $200‑billion U.S. investments move forward.

South Korea’s $200 billion investment in the United States, which President Donald Trump said would transform America “for generations,” is not yet finalized in full.

The South Korean investment blueprint includes nuclear power plants, a natural‑gas power facility in Texas, and potentially the long‑planned Alaska liquefied natural gas project.

Trump posted on Truth Social late Wednesday that the two nations had agreed to move forward on the Alaska LNG venture, estimating its value at $50 billion. This prompted a response from South Korean President Lee Jae‑myung, who stressed that participation in some projects remains tied to commercial considerations.

In an X post Thursday local time, Lee said that involvement in the Alaska LNG project hinges on its financial viability and legal compliance. He added that investments in nuclear power plants would also require a plant‑by‑plant assessment of commercial feasibility.

The US‑South Korea joint statement Wednesday also noted that work on the project is contingent on “commercial reasonableness,” without detailing allocations toward the venture.

The Alaska LNG project aims to move natural gas roughly 1,300 km (800 miles) from fields on Alaska’s North Slope to the state’s southern region, where it would be liquefied for export to markets including Asia, according to Yonhap. The initiative has long faced scrutiny over its economics, given the substantial upfront capital required.

Industry Minister Kim Jung‑kwan labeled it “high‑risk” last year and said participation would be challenging unless the project could generate sufficient cash flow.

Overall, the investment package allocates $22.3 billion for a 6,472‑megawatt natural‑gas power plant in Encinal, Texas, which will supply electricity to nearby data centers. The venture will be led by developer Related Cos. and U.S. power provider NextEra Energy.

Trump said the investments would turn South Korea’s commitments into “huge construction projects” and create “tens of thousands of American jobs.”

“These are massive energy projects, adding power capacity in the United States,” Trump remarked. “This is new construction, new manufacturing, and great jobs for American workers.”

The two countries said they would seek to broaden Korean firms’ involvement in the Texas project across equipment supply, engineering, construction, and long‑term operations and maintenance. The U.S. also plans to give Korean companies opportunities to supply equipment, including turbines, for similar projects domestically.

Another $120 billion has been earmarked for plans to build eight large‑scale nuclear reactors in the United States. Of that sum, $100 billion is designated for construction costs and $20 billion for contingency reserves.

The nuclear accord was signed by both governments as well as Westinghouse Electric, Korea Electric Power Corp., and Korea Hydro & Nuclear Power. The plan also calls for Korean firms to pursue a potential significant minority stake in Westinghouse, with terms subject to commercial negotiations.
