ZOSKVEE Nx9 Three-Proof Smart Watch

The ZOSKVEE Nx9 is a 49 mm wearable with a round TFT touch screen and silicone strap. Weighing 59 g, it connects via Bluetooth for calls, smart reminders and a remote self-timer. A 400 mAh battery delivers 7 to 14 days of continued flight time between charges.

Suited to adults who want daily health tracking

Heart rate, blood pressure, blood oxygen and sleep monitoring run alongside step counting and multi-sport modes. Buyers who need cellular independence or an always-on display will not find those features here. The life-waterproof rating handles splashes but not swimming or diving.

Sustained use stays consistent over a week

The 400 mAh cell maintains sensor sampling and Bluetooth linkage across the full 7 to 14 day window without a mid-week recharge. Touch-button operation remains responsive during long days, and the silicone band keeps its grip through sweat and temperature shifts.

Questions about this item

What smartphone operating system is required to pair with the Nx9 watch?

Can the 49 mm case and 13.5 mm thickness fit under a standard shirt cuff?

The 49 mm diameter and 13.5 mm profile sit close to the wrist; most cuffs accommodate it without catching.

How can I confirm the heart rate and blood oxygen sensors are tracking correctly?

Compare the on-wrist readings with a clinical device at rest; the TFT display shows live values for each metric.
