Garmin has rolled out its latest beta software update for its high-end smartwatches, fixing alarm issues on the Enduro 3 and refining workout timers across Fenix 8 and related models.
The phased release, version 21.20, is now live for half of enrolled Public Beta users, with wider availability expected within the next few days.
Garmin’s newest beta build targets premium devices, including the Fenix 8 Pro (Micro LED, AMOLED, and Solar editions), Enduro 3, Fenix E, and Tactix 8 variants. The update arrives over the air (OTA) and can be manually requested by users enrolled in the Public Beta programme.
While the rollout is currently limited to 50% of testers, anyone in the programme can force the update through the watch’s system menu. This approach reflects Garmin’s ongoing strategy of refining its flagship wearables through incremental beta cycles before pushing stable releases.
The headline fix addresses a frustrating alarm bug on the Enduro 3, where alerts previously stopped after a single beep. Garmin has also corrected blank rest timers during workouts on Solar devices, alongside improvements to data fields on map split screens and ski activity summaries.
These tweaks follow a string of recent beta builds, underscoring Garmin’s brisk development pace as it polishes its adventure and training-focused watches.
However, the update comes with caveats. As with earlier beta releases, ECG, Dive, and Aviation features remain disabled during testing. Garmin has explained that certification requirements prevent these advanced functions from being included in beta builds, though they will return in future live updates.
Users who rely on these features are advised to avoid beta enrolment or backdate to stable software if needed. This trade-off highlights the balance Garmin must strike between rapid iteration and regulatory compliance.
The benefits include early access to fixes and new tools, but the risks involve occasional instability and missing features. Garmin’s forums and Beta Wiki provide guidance on troubleshooting, bug reporting, and backdating software if issues arise. Those preferring a smoother experience may wish to wait for stable releases, which typically follow within a quarter.
Garmin’s beta strategy mirrors broader trends in the smartwatch market, where brands like Apple and Samsung also rely on phased testing to refine health and fitness features.
The difference lies in Garmin’s focus on rugged, outdoor-ready devices, where reliability during workouts and expeditions is paramount. Therefore, even small fixes, like ensuring alarms function correctly, carry weight for athletes and adventurers who depend on these watches daily.
Garmin’s latest tweaks may seem minor, but they reinforce the company’s commitment to iterative improvement across its premium lineup.
