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.

Questions about this item

What size wrist will the 1.39 inch case and PU strap fit?

The 1.39 inch alloy metal and plastic case pairs with a PU strap that adjusts to most adult wrists; the IP68 rating means it survives submersion during daily wear.

How do I charge the 280mAh battery using the USB magnetic 2 Pin cable?

Align the two magnetic pins on the cable with the contacts on the watch back; the magnets snap into place and charging begins automatically.

When will the 280mAh battery need replacing after daily ECG and blood sugar tracking?

Expect 4 to 7 days per charge and roughly 30 days on standby; the sealed 280mAh cell is not user-replaceable, so plan for a new watch when capacity fades.
