Apple Watch Series 10 GPS 42mm - Thinner Design, Bigger Screen and Sleep Apnea Alerts

Apple Watch Series 10 GPS 42mm is Apple’s mainstream smartwatch for 2024, pairing a larger 42mm display with the thinnest case the company has offered so far while keeping familiar fitness, health and safety features in an aluminum body aimed at everyday wear.

Design, Sizes and Display

The Apple Watch Series 10 line introduces two case sizes, 42mm and 46mm, replacing the prior 41mm and 45mm options and giving the 42mm GPS model a noticeably larger screen area than the Series 9 it succeeds. Engadget notes the new sizes at 42mm and 46mm.

According to Apple’s technical specifications, Apple Watch Series 10 uses an LTPO3 OLED Always-On Retina display that Apple calls a wide-angle OLED, designed to be up to 40% brighter when viewed at an angle compared with earlier models. Apple lists the LTPO3 wide-angle OLED display and the viewing-angle brightness gain.

The 42mm case offers an edge-to-edge display with Ion-X front glass on aluminum models, while titanium cases use a sapphire front crystal in the same 42mm size for added scratch resistance. Apple’s spec sheet distinguishes Ion-X glass for aluminum and sapphire crystal for titanium.

Core Hardware and Battery Life

Inside, Apple Watch Series 10 runs on the S10 SiP with a built-in 4-core Neural Engine, giving the watch enough on-device processing to handle features such as double tap, on-device Siri and automatic workout detection without relying solely on the paired iPhone. Apple’s launch announcement details the S10 SiP and Neural Engine.

The 42mm GPS configuration carries 64GB of internal storage, matching the capacity across the Series 10 family and allowing room for offline music, apps and watch faces. Apple’s tech specs list 64GB capacity for Series 10.

Battery life remains rated at up to 18 hours of “all-day” use under Apple’s typical mixed-use profile, with up to 36 hours available when Low Power Mode is enabled for longer stretches away from a charger. Apple’s specifications quote up to 18 hours of all-day battery and up to 36 hours in Low Power Mode.

Fast charging is supported; Apple specifies that the built-in rechargeable lithium-ion battery can be recharged to about 80% in roughly 30 minutes when paired with an appropriate fast-charge power adapter and charging cable. Apple’s documentation highlights fast charging to 80% in about 30 minutes.

Health, Fitness and Safety Features

Apple Watch Series 10 GPS 42mm includes a long list of health sensors, combining an electrical heart sensor for ECG readings with a third-generation optical heart sensor and a blood oxygen sensor for SpO2 estimates. Apple’s specs enumerate the electrical heart sensor, optical heart sensor and blood oxygen sensor.

The watch’s sensor suite also adds a temperature sensor, compass, always-on altimeter, high-g accelerometer, high dynamic range gyroscope, ambient light sensor, depth gauge and water temperature sensor, expanding its capability for swim tracking, snorkeling and outdoor workouts. Apple lists the temperature, depth and water temperature sensors alongside GPS-related components.

Building on earlier Apple Watch generations, Series 10 adds sleep apnea notifications that rely on overnight respiratory and heart rate data, issuing alerts if signs suggest possible sleep apnea so users can seek medical evaluation. Apple’s announcement calls out new sleep apnea notifications as a headline feature.

Workout tracking for the 42mm GPS model covers custom workouts, customizable workout views, training load estimates, heart rate zones, race route features, pacer tools and advanced running metrics such as stride length, ground contact time and vertical oscillation. Apple’s spec page lists the custom workout and advanced running metrics supported.

For outdoor navigation, Series 10 offers a hiking workout profile, a compass with bearing, incline, elevation and coordinates, custom waypoints, automatically generated waypoints based on cellular connectivity, Backtrack GPS data to retrace steps, offline maps with custom route creation and topographic maps for thousands of national and regional parks in the U.S. along with curated hikes across all 63 U.S. national parks. Apple’s documentation summarizes the hiking and offline mapping tools.

Safety features include Emergency SOS, international emergency calling, Crash Detection, Fall Detection, noise monitoring and Backtrack, matching the behavior of recent Apple Watch generations and relying on the S10 SiP and Neural Engine for responsiveness. Apple’s newsroom article groups Crash Detection, Fall Detection and emergency features together.

Water Resistance and Outdoor Use

Apple Watch Series 10 retains a water resistance rating of 50 meters under ISO standards, making it swimproof for pool and open-water workouts and suitable for recreational water use. Apple’s specs state a 50m swimproof water resistance rating.

Dust resistance is specified at IP6X, matching the dust protection introduced with earlier models and helping the 42mm GPS version stand up to sand, dirt and everyday exposure in outdoor settings. Apple cites an IP6X dust resistance rating for Series 10.

With the depth gauge and water temperature sensor, Apple Watch Series 10 can support snorkeling and shallow dives down to 6m/20ft when used with supported third-party apps, while still maintaining its 50m water resistance rating for general swimming. A detailed review from DC Rainmaker describes the depth gauge and snorkeling support.

Connectivity, Software and Media Playback

The 42mm GPS configuration of Apple Watch Series 10 connects via Wi-Fi and Bluetooth to a paired iPhone and includes a second-generation Ultra Wideband chip for more precise device finding and integration with compatible accessories. Apple’s spec sheet lists Wi-Fi, Bluetooth and a second-generation Ultra Wideband chip.

Out of the box, Series 10 ships with watchOS 11, which adds features such as a redesigned Photos face, an updated Smart Stack of widgets, a new Vitals app that summarizes overnight health metrics and the ability to pause and further customize Activity rings and goals. Apple’s newsroom launch notes watchOS 11 and its Vitals app and ring customization.

One notable change with Series 10 versus earlier mainstream Apple Watch models is speaker media playback; Apple enables the watch’s speakers to play music and podcasts directly, instead of limiting them to alerts and calls, which reviewers describe as useful when AirPods are not available. Engadget points out that Series 10 speakers now support media playback.

Voice isolation for calls is another addition specific to Apple Watch Series 10, leveraging the Neural Engine and microphone system to reduce background noise so voices sound clearer in loud environments. T3’s review calls voice isolation a feature unique to Series 10 within the lineup.

Price, Configurations and US Positioning

Apple positions Apple Watch Series 10 as its core Apple Watch option, with a starting price of $399 in the US for the GPS-only model at launch. Engadget’s coverage cites a $399 starting price for the GPS-only Series 10

Aluminum models make up the mainstream configurations for the GPS-only 42mm size, while titanium sits above as a more premium option and replaces stainless steel in the current lineup. Engadget mentions aluminum and titanium cases, with titanium replacing stainless steel.

In the US market, Apple Watch Series 10 is sold directly by Apple Inc., Cupertino, CA, via Apple’s own retail and online channels and is also carried by major US electronics and wireless retailers as the default Apple Watch for most buyers, while Apple Watch Ultra 4 sits above it for more dedicated outdoor and diving use. Apple’s newsroom article frames Series 10 as the mainline Apple Watch alongside Ultra.

Comparison With Previous Apple Watch Models

Compared with Apple Watch Series 9, the Series 10 family’s 42mm and 46mm sizes deliver a bigger display in both cases and a thinner profile that is about 9.7mm thick, down from roughly 10.7mm on Series 9, for a noticeable change on the wrist. DC Rainmaker notes a 9.7mm thickness for Series 10 versus 10.7mm on Series 9.

The screen resolution on Series 10 also steps up from Series 9; one review lists resolutions of 374 x 446 for the 42mm and 416 x 496 for the 46mm case compared with lower-resolution panels on the prior generation, helping text and complications look sharper. Engadget’s write-up mentions 374 x 446 and 416 x 496 resolutions for the two sizes.

Feature-wise, Series 10 borrows depth and water temperature sensors from Apple Watch Ultra and adds sleep apnea notifications and speaker media playback that were not present on the mainstream Series 9, moving more high-end capabilities into Apple’s standard watch line. Apple’s newsroom article highlights depth and water temperature sensing and sleep apnea notifications.

Use Cases and Who It Suits

Apple Watch Series 10 GPS 42mm is targeted squarely at iPhone owners who want a daily smartwatch for activity tracking, notifications and basic health monitoring without paying for cellular connectivity or the more extreme sports focus of Ultra models. A Tom’s Guide review positions Series 10 as the go-to Apple Watch for most users.

The combination of 18-hour battery life, advanced workout metrics, sleep tracking with apnea alerts, Crash Detection and Fall Detection makes the 42mm GPS model broadly suited to commuters, casual athletes and users paying attention to their overnight health metrics, provided they accept daily or near-daily charging. PCMag’s review cites the 18-hour battery estimate and highlights the expanded fitness and health tools.

Those who frequently spend nights away from power outlets or who need multi-day GPS logging and extended depth tracking may find Apple Watch Ultra models more appropriate, but for mainstream US buyers, Series 10 GPS 42mm balances features, price and size in Apple’s current watch lineup.
