Honor Watch Fit 6 can alert its wearer to signs of atrial fibrillation and premature beats, and Honor says those alerts hold a Class II medical device registration in China.
- Honor’s Watch Fit 6 product page lists pulse-wave atrial fibrillation and premature beat alerts with a Class II medical device registration.
- The watch also offers sudden cardiac death risk screening, sleep apnoea monitoring and a sleep risk assessment.
- A gym mode records each exercise, the number of reps and the weight lifted.
- The 1.98-inch display reaches 3,000 nits peak brightness, and Honor says the watch passes more than 10 MIL-STD-810H military-standard tests.
- Honor’s China store lists the black version and the product page shows five colours, but no price or release date has been published.
- Honor has not yet filled in its spec sheet, so battery life, weight, water rating and GPS details are unconfirmed.
What it means for athletes
Watch Fit 6 lets the wearer log a gym session set by set on the wrist and get a heart rhythm alert from the optical sensor on the same device. Honor’s earlier sudden cardiac death screening, on Watch GS 5, uses a measure called deceleration capacity, explained in the next big health feature coming to smartwatches.
The medical registration is Chinese, and Honor has not announced a launch outside China. The nearest alternative sold in the UK is Huawei Watch Fit 5 Pro, and the wider field is in the best fitness tracker guide.
