If you strap an older Samsung watch to your wrist every morning, you have some great maintenance news waiting for you. Following the initial software rollout for its premium Galaxy Watch 8 and Watch 7 models, the tech giant is officially extending its May 2026 security update to previous generations of wearables.
The new software package targets and fixes 36 distinct vulnerabilities discovered in previous versions of the wearable firmware. According to SamMobile, the company is currently deploying the build exclusively to non-cellular, Wi-Fi-only variants in South Korea. However, standard development patterns suggest that tech enthusiasts in other regions should see the update land on their personal devices over the coming days.
The eligible device lineup
Samsung is keeping its update promises alive by targeting all models that remain actively eligible for digital support. The rollout covers seven distinct versions, ranging from recent budget-friendly releases to beloved flagship smartwatches from a few years ago.
The software builds are dropping under specific identification numbers. To check the exact build designation associated with your particular hardware generation, you can reference the official firmware roadmap outlined below:

It is always a smart habit to perform these routine checkups while your device rests on its magnetic charging cradle with a solid battery level. Taking a quick moment to update ensures your everyday tracker stays shielded from potential digital exploits while you go about your routine.
