ZOSKVEE E400 1.39 inch Smart Watch Brown

1.39 inch HD Round Smart Watch

The ZOSKVEE E400 is a wearable device with a 1.39 inch high-definition display running at 360x360 resolution. It targets adults who want continuous health insights such as ECG analysis, non-invasive blood sugar estimates, heart rate, blood pressure and blood oxygen readings. The alloy metal and plastic shell with a brown PU strap suits daily office or casual wear. IP68 waterproofing allows use while washing hands or in rain.

Upgrade from basic trackers

This watch replaces simple step counters that lack clinical-grade sensors. The jump is worth it when you need real-time ECG analysis with chest stickers or belt monitoring alongside multi-sport tracking. Battery life reaches 4-7 days per charge with up to 30 days standby, reducing the charging frequency compared to many colour-screen rivals. Magnetic 2-pin USB charging keeps the routine simple.

Check phone OS and language needs

Verify your phone runs Android 5.0 or iOS 10.0 and above before ordering. The interface supports English, German, French, Spanish, Italian, Portuguese, Russian and many other languages, but confirm your preferred tongue is listed. No internal storage for music or apps is mentioned, so the watch relies on a constant Bluetooth link to your handset. Chest stickers or an ECG belt are required for the advertised ECG function.
