Main article: Apple Watch § Hardware

The Apple Watch Ultra hardware is generally similar to the main Apple Watch line (with the first-generation model based on the Apple Watch Series 8), but is differentiated by their rugged titanium casing, a larger 49 mm band, and a larger display with a flat crystal and higher brightness of up to 2000 nits. It supports multi-band GPS on L1 and L5.[3] The Ultra includes a new, orange-colored “Action” button, which can be mapped to different functions, as well as an emergency siren feature.[3] The Apple Watch Ultra contains a battery 76% larger than that of the Series 8, which Apple rated at 36 hours of usage without using power saving modes (as opposed to Apple's rating of 18 hours on the main line). A power saving mode which reduces the amount of heart rate readings and GPS polling can extend its battery life to around 60 hours.[3] All Apple Watch Ultra models include cellular connectivity.[3]

The Apple Watch Ultra has a water temperature sensor, and carries WR100 and EN13319 certification. Apple rates the device for diving to depths of up to 40 metres (130 ft); a new “Depth” app is included for displaying depth and water temperature information, while Apple partnered with Oceanic Worldwide to release the subscription-based “Oceanic Plus” app for more advanced dive computer functionality.[4]

Models

[edit]

The first-generation Apple Watch Ultra was unveiled September 7, 2022 alongside Apple Watch Series 8, and began shipping September 23, 2022.[5]

The Apple Watch Ultra 2 was unveiled on September 22, 2023, alongside the Apple Watch Series 9; alongside the updated hardware inherited from Series 9, its screen brightness was further increased to 3000 nits.[6][7][8] In December 2023, the Apple Watch Series 9 and Ultra 2 were temporarily pulled from the U.S. market due to patent litigation by Masimo. They returned to sale on January 18, 2024, with models sold after this date having blood oxygen monitoring features disabled.[9] On September 9, 2024, Apple unveiled a black colour option for the Apple Watch Ultra 2, as well as a sleep apnea detection feature.[10] On August 14, 2025, Apple announced a software update re-enabling blood oxygen monitoring features for U.S. users. Sensor data is now analysed on a paired iPhone instead of the watch.[11] On September 9, 2025, Apple unveiled the Apple Watch Ultra 3 with an official release date of September 19, 2025. [12]

Reception

[edit]

Victoria Song of The Verge felt that the first-generation Apple Watch Ultra was "a great first attempt at a rugged smartwatch" and "legitimately good for weekend warriors and intermediate athletes", noting features such as the Action button (which she believed should be added to the main Apple Watch line as well) and multi-band GPS, and the larger screen being easier to read. She felt that the Ultra benefitted from the new mapping and compass features (such as BackTrack) introduced by watchOS 9. She noted that Apple's battery life estimations were conservative in comparison to real-world use, where she regularly got closer to 48 hours of battery life during regular exercise use without using power saving modes, and another Verge staff member reported 56 hours via general, non-fitness use at home. However, she noted that the Apple Watch line still lacked certain features (including longer battery life, offline maps and trail navigation, and transflective displays) and fitness metrics in comparison to competitors such as Garmin and Polar, but that watchOS still "runs circles around fitness watches in terms of connectivity and simplicity".[3]

Criticisms centered on the upgrades feeling minor compared to the original, with the holding steady at $799 and the unchanged, making it less ideal for non-athletes despite its appeal for divers and hikers. In 2025, the Apple Watch Ultra 3 was generally well-received for its refined features, particularly in battery endurance and connectivity, though some reviewers pointed out limited design evolution. Android Authority scored it 9/10, praising the upgraded 42-hour battery life (up to 72 hours in low-power mode) that reliably supported two days of GPS-intensive activities, along with doubled signal strength for messaging and location sharing, calling it "Apple’s best adventure watch yet." New tools, including trend notifications and enhanced sleep tracking, were highlighted as valuable additions for adventurers, with Wareable giving it a perfect 5/5 for overall tracking accuracy and ecosystem integration. However, the design saw minimal changes from the Ultra 2, retaining the 49mm case, which critics noted as a potential drawback for those seeking a slimmer profile. YouTube reviewers, such as those from tech channels, echoed that it was "worth the for adventurers" due to these and enhancements. Across all models, critics consistently commended the Ultra series for excelling in athletic and diving scenarios, with deeming the original "the ultimate sport performance watch" for its scuba certification and multisport tracking, while emphasized its superiority for runners over slimmer alternatives. The bulky form factor, however, was a recurring complaint for daily wear, often described as oversized and less comfortable for non-active routines. Additionally, the blood oxygen monitoring feature's disablement in the U.S. prior to a 2025 software update ( 11.6.1) due to a dispute negatively impacted some scores for health functionality, though the redesigned version restored access on models like the Ultra 2 via processing.

Market impact

The Apple Watch Ultra series has carved out a premium niche within Apple's wearable lineup, typically accounting for 5-10% of overall Apple Watch sales despite its higher price point. This positioning targets adventure enthusiasts and athletes seeking rugged durability and advanced outdoor features, differentiating it from more mainstream models like the Series and SE lines. In the United States, the Ultra models accounted for approximately 9% of total Apple Watch sales during 2024. The series' influence extends to competitors, notably inspiring Samsung's Galaxy Watch Ultra, which adopted a similar rugged design and titanium construction in response to the Apple Watch Ultra's market entry. Sales performance for the first-generation Apple Watch Ultra, launched in September 2022, exceeded 1 million units within its initial year, driven by strong demand for its specialized capabilities. The second-generation model, released in 2023, contributed to Apple's broader wearables revenue, which reached $40 billion that —though overall shipments declined 19% globally in 2024 amid market saturation. The third-generation Ultra, released in September 2025, contributed to sales recovery in the latter half of 2025, bolstered by new features like satellite connectivity, even as it faces intensifying competition from Garmin's high-end models such as the Fenix series, which reported 12% year-over-year overall revenue growth in Q3 2025. The Apple Watch Ultra has significantly impacted the wearables industry by popularizing integrated functionality, marking the first mainstream certified for recreational up to 40 meters via the Oceanic+ app partnership. This innovation expanded Apple's ecosystem into adventure sports, enabling seamless integration with apps for activities like , , and multisport tracking, and attracting endurance athletes previously reliant on specialized devices. A key 2025 software update restored blood oxygen monitoring on U.S. models through a redesigned , resolving a sales dip caused by a 2023-2024 import ban that halted shipments and disabled the feature on affected units. Challenges have included patent disputes, particularly the ongoing lawsuit with over technology, which led to temporary feature limitations and U.S. sales suspensions starting December 2023, though global availability remained largely unaffected outside regulatory pauses. As of November 2025, the U.S. International Trade Commission (ITC) is scrutinizing the redesigned blood oxygen feature, potentially affecting its long-term availability. These issues highlighted vulnerabilities in supply chains but ultimately prompted Apple to innovate around restrictions, maintaining the Ultra's competitive edge in premium outdoor wearables.
