Honor Watch GS 5 Review: The Smartwatch with a Unique Heart Health Feature (2026)

The smartwatch market is about to get a groundbreaking addition, and it's not from the usual suspects! Honor has unveiled its latest innovation, the Watch GS 5, which introduces a unique twist to heart health monitoring. But will this feature be a game-changer or a gimmick?

The Honor Watch GS 5 is a sleek and lightweight smartwatch, packed with health-focused features. Its standout claim is the ability to warn users of sudden cardiac arrest, a potentially life-saving capability. But here's where it gets controversial—can a smartwatch really do that?

The watch is set to hit the Chinese market on January 19th for pre-orders, with no word yet on a global release. Honor's previous smartwatches have made their way to Europe, so there's a chance this one might follow suit. We've already reviewed some of their wearables, and they've impressed us with their unique features.

Honor has kept the technical specs and pricing under wraps for now, focusing on the watch's health-related capabilities. They claim the watch weighs a mere 0.92 oz and is just 0.39 inches thick, with an impressive 23-day battery life in power-saving mode.

The heart of the matter (pun intended) is the watch's ability to assess cardiovascular risk and predict cardiac arrest. This is achieved by measuring the heart's deceleration capacity, a parameter not typically tracked by Apple, Garmin, or other major brands. But is this feature medically sound, and will it pass regulatory scrutiny in regions like Europe?

Deceleration capacity is a known concept in medicine, but it's not a standard measurement in clinical practice. Honor's implementation of this feature could be a bold step forward in wearable health tech, but it might also raise concerns about accuracy and medical certification.

So, is the Honor Watch GS 5's heart health feature a revolutionary breakthrough or a marketing gimmick? The jury is still out, but one thing's for sure—it's a bold move that will undoubtedly spark discussions in the tech and medical communities. What do you think? Is this a feature you'd trust with your heart?
