HONOR Watch Fit 6 brings certified AFib alerts and a 3,000-nit display

HONOR has just launched another smartwatch and the design looks very familiar. The new Watch Fit 6 could easily pass for an Apple Watch Ultra at first glance. But look past the styling and there’s actually quite a bit going on here, particularly when it comes to heart health.

For now, HONOR is accepting reservations for the Watch Fit 6 in China, but it hasn’t confirmed pricing or a date for wider availability. There’s also no indication yet that the full set of health features would be offered outside China.

A familiar design with a few practical touches

There’s a squarish case, raised edges, a rotating crown and an orange colour option with a sporty strap. HONOR also offers blue, green and two black finishes, so the overall look isn’t quite as dependent on Apple’s colour palette as the launch images might suggest.

Despite the chunky appearance, HONOR quotes a weight of just 31.8 grams for the watch body. The display measures 1.97 inches, uses AMOLED technology and has a 410 x 502 resolution, 60Hz refresh rate and advertised peak brightness of 3,000 nits. On paper, those are pretty decent specs.

HONOR says the watch has passed more than ten MIL-STD-810H durability tests. There’s also 5 ATM water resistance.

The 620mAh battery is another promising detail. HONOR describes battery life as long-lasting, but has not published a clear number of days for typical use, so there’s no point guessing how often you’ll need the charger.

Heart monitoring is the bigger story

The more unusual part of the Watch Fit 6 sits behind the case. HONOR says its optical sensor can support alerts for possible atrial fibrillation and premature heartbeats, with the pulse-wave alert software holding Class II medical device registration in China.

HONOR is also including sudden cardiac death risk screening. The system uses a measure known as heart rate deceleration capacity, or DC, which reflects aspects of how the autonomic nervous system regulates heart rate. It produces risk categories and reports, rather than detecting that a cardiac arrest is about to happen, so it’s worth keeping the claim in perspective.

This isn’t HONOR’s first attempt at this kind of monitoring. We covered similar cardiac risk screening on the HONOR Watch GS 5 earlier this year, while the more recent Watch 6 Pro goes further with an emergency response system for suspected cardiac arrest.

The rest of the health package includes overnight HRV trends, sleep apnoea risk screening, heart rate, blood oxygen and stress tracking. There’s also a daily energy estimate based on workout intensity, sleep and heart-rate information.

More than another long list of sports modes

HONOR has put some extra effort into gym tracking. The Watch Fit 6 can log exercises, reps and weights, and even show which muscles you’ve worked. That’s a step up from simply recording your heart rate during a gym session.

Runners get training plans and running-form analysis, while badminton and football have their own detailed tracking features. There are over 100 sports modes in total, so there’s plenty to play with.

You also get Bluetooth calling, NFC, downloadable apps and HONOR’s YOYO voice assistant with DeepSeek integration. Just bear in mind that these are features of the Chinese version, so international availability may differ.
