Xiaomi sub-brand Huami announced the Amazfit Verge 2 smartwatch earlier today at a press event in China, reported GizChina today.

The Verge 2 now offers eSIM support, something the original Verge smartwatch didn’t offer. That means you can use the Verge 2 as a standalone device to make and receive calls. According to Huami, the new smartwatch is compatible with all major carriers in China. We don’t know whether the global version retains the eSIM support.

Another major upgrade is a real-time electrocardiogram (ECG). The Verge 2 features a custom always-on AI chip with a cardio biometrics engine for more accurate heart rate monitoring. The chip also allows for real-time ECG screening for abnormalities like arrhythmia and atrial fibrillation.

For the privacy minded, Huami said that up to 60 minutes of ECG data is stored locally for seven days.

In terms of hardware, the Verge 2 features a 1.39-inch circular AMOLED display with 454 x 454 resolution, an IP68 rating for water and dust resistance, GPS, NFC, the Qualcomm Snapdragon Wear 2500 SoC, 512MB of RAM, and 4GB of internal storage. The 420mAh battery supposedly gets you up to 28 hours of battery life while on a 4G connection.

Finally, the Verge 2 swaps out the polycarbonate chassis of its predecessor for a microcrystalline zirconium ceramic frame. The material change should make the smartwatch more durable than the original Verge.

The standard edition of the Verge 2 is now available in China for 999 yuan (~$145). The ECG version will be available in July for 1,299 yuan (~$190). There’s also an Avengers edition with a white color option and custom watch faces that will launch in July for 1,499 yuan (~$215).

According to Huami, the Verge 2 will be available in the U.S. later this year. Until then, you can still pick up the original Verge for a little under $160 at the link below.
