Garmin gives compatible watches several ways to receive software updates, Apple supports updating from either the watch or its paired iPhone, and Wear OS update steps depend more heavily on the watch’s manufacturer and model. None has a universal update schedule or guaranteed support lifespan: check eligibility for your exact watch, and distinguish operating-system updates from system components and apps.
How the update experience differs
| Platform | How updates arrive | What determines eligibility | What to expect about timing |
|---|---|---|---|
| Garmin | Garmin Connect on a paired phone, Garmin Express on a computer, or built-in Wi-Fi on compatible watches. | The exact watch model and the update methods it supports. | Garmin says a Connect-delivered update may take up to a week to download before installation or an installation prompt. This is not a universal release schedule. |
| Apple Watch | Directly on the watch or through its paired iPhone. | Watch model, iPhone model, and iOS version. | Apple’s instructions do not establish a fixed rollout window. |
| Wear OS | Often automatically while charging and connected to Wi-Fi; a manual system-update check or Play Store update may be needed. | The watch manufacturer, model, and software version. | Overnight installation is common, not guaranteed on a particular night. |
For all three platforms, a feature announcement or a newer version available on another watch does not prove that your model is eligible. Check the support page and update history for your exact device.

How to update a Garmin watch
Garmin supports more than one delivery route, but the options depend on the watch. Garmin says compatible devices paired with Garmin Connect can download updates in the background; after an update is released, delivery through Connect may take up to a week before it installs or prompts you to install it. Garmin Express checks for and downloads updates when you connect a compatible watch to a computer. Some watches can update over built-in Wi-Fi. See Garmin’s software installation guidance and your model’s manual for applicable steps.
Garmin’s Forerunner 955 software history illustrates why model-specific records matter: its listed version and release date apply to that watch, not to every Garmin model. Garmin also says beta software is available only for select models. Its February 24, 2026 announcement named Venu X1, vívoactive 6, fēnix 8 Pro, Forerunner 570, and Forerunner 970 in a feature-update release, while discussing some Garmin Connect app updates separately. That release is an example of selected-model distribution, not a promise of a recurring cadence or universal availability. Garmin’s feature-update page is distinct from an individual watch’s software history.

How to update an Apple Watch
Apple supports updating either on the watch or through the paired iPhone. Before installing, Apple advises updating the iPhone software, connecting the iPhone to Wi-Fi, and ensuring the watch has at least 50 percent charge. The watch and iPhone must be a compatible combination. If the watch cannot use the latest major watchOS release, Software Update shows the newest version available for that particular watch. Follow Apple’s Apple Watch update instructions and check its live compatibility information before relying on a version-specific eligibility list.
Compatibility changes between releases. For example, Apple’s June 9, 2025 watchOS 26 announcement listed Apple Watch Series 6 or later, Apple Watch SE (2nd generation), and all Apple Watch Ultra models, paired with iPhone 11 or later running iOS 26. Those requirements describe that release; they should not be treated as evergreen eligibility for later watchOS versions.

How Wear OS updates work
Wear OS guidance distinguishes the watch’s operating-system version, system version, and the phone’s Wear OS app version. Google’s general guide says only Wear OS 2 or newer watches can get updates, but procedures vary by manufacturer, device, and software version. For an exact eligibility answer, use the watch maker’s support page as well as Google’s update guidance.
Google says updates are often installed overnight while a watch is charging and connected to Wi-Fi. Keep the watch powered on and online; if no update arrives, check Settings > System > About > System updates. App updates are separate: open the Play Store on the watch to check for them. An app update does not necessarily update Wear OS itself.

Wear OS 3 can be a migration, not a routine patch
On supported devices, upgrading to Wear OS 3 can reset the watch. Google warns that the process erases locally stored data and installed apps and their data, unpairs the phone, and may change app or feature availability. The manufacturer determines whether a particular watch can upgrade. Check Google’s Wear OS 3 upgrade information and the manufacturer’s instructions before starting.
Why your watch may not have received an update
- The model is not eligible. Software availability is model-specific, especially for Garmin and Wear OS. Check the exact watch’s support page and release history.
- The rollout has not reached your watch. Garmin says Connect delivery may take up to a week; Wear OS overnight installation is described as common, not guaranteed. Apple’s instructions provide no fixed rollout window.
- A prerequisite is missing. For Apple Watch, confirm the paired iPhone and iOS compatibility, Wi-Fi connection, and at least 50 percent watch charge. For Wear OS, leave the watch powered on, charging, and connected to Wi-Fi.
- You are checking the wrong kind of version. A phone companion app, watch app, system component, and watch operating system are distinct update targets. Check the relevant update screen for the software you mean.
What the comparison does—and does not—tell you
Garmin’s multiple delivery methods can be convenient when a watch supports them, while Apple documents a direct watch route and a paired-iPhone route with explicit prerequisites. Wear OS offers automatic installation in many cases, but model-specific procedures and support are set by device makers. The available official guidance does not establish a comparable cross-platform average delay, a guaranteed update cadence, or a universal number of supported years. For a specific watch, its model support page and release history are more useful than a platform-wide expectation.
