Zepp Z Smartwatch Review 2021: How Good it is?

Zepp Z Smartwatch Review, Zepp Z review

Huami owns both Zepp and Amazfit brands. Zepp Z is the second smartwatch from the family of Zepp. It comes with a handful of features and functionalities. 

It has everything to solidify its position in the premium entry category in terms of design and performance. Unlike copying Apple’s smartwatch design, as most others do, Zepp managed to deliver a classy and standard look to its product, thanks to the design team.

Zepp Z Health and Fitness Smart Watch with Titanium Alloy Crafting, 15 Days Battery Life, Online and...

Is it the best alternative to Samsung Galaxy Watch 3 and Apple Watch Series 6? You can decide after reading our in-depth Zepp Z Smartwatch review. 


  • Classic watch Design 
  • Battery Life for up to 15 days (about two weeks) 
  • 1.39″ AMOLED Display 
  • Enabled GPS+GLONASS positioning. 
  • Beautiful rotating bezel with hairline lines. 
  • Voice assistance by Amazon Alexa. 

The Zepp Z has a classical look and design. The Zepp Z’s upper body is crafted with aerospace quality polished Titanium alloy (TC4), which is feather-light(weighing only 40 grams), stylish and sturdy. The TC4 guarantees you complete protection from corrosion.

Furthermore, the NanoTech Coating (NTC) protects your device from scratch and other physical damage. The bottom of the case is made with PA+GF material; a stable and robust plastic augmented glass for better water, chemical, and aging resistance. 

Classic crown design coupled with an engraved dial and button provides a luxury appearance and passive protection. The three buttons provided at the side of the watch can be used to control the smartwatch. 

The 22 mm wrist band is made with high-quality leather. The premium quality leather is smooth, and it does not cause any skin irritation.  


Zepp Smartwatch display

Zepp Z has succeeded in providing an impressive high-quality display with an AMOLED touchscreen and 454×454 resolution. The 326 PPI display ensures a complete NTSC wide-color spectrum by projecting every data on the screen. You should know that the Amazfit GTR2 watch is also featuring the same display.

For added protection, the Zepp Z has given a tempered glass and anti-fingerprint coating. You can personalize the display with over 50 different trendy watch faces based on your outfit, mood, or occasion. Furthermore, you can even set your own photo as the wallpaper.

Health Tracking Features

Sleeping with Zepp Smartwatch

The Zepp Z comes with an advanced digital health management system. It uses a second-generation BioTracker 2.0 PPG optical sensor which is capable of monitoring heart rate 24/7. The smartwatch not only monitors your heart rate but also alerts abnormally high heart rates.

An ECG version of the Zepp Z smartwatch is available in China. However, the Zepp Z with ECG costs you few more bucks. As of now, this feature is not available in the USA till the FDA clinically validates it. If you are looking for an FDA-approved ECG watch, check our latest article on the best ECG smartwatches in 2021. 

This smartwatch can also track your various sleep stages (deep, light, and REM), including evening naps. Based on your sleep quality, it gives you a sleep score. 

It also features a blood oxygen sensor to track real-time blood oxygen levels. It will display the SpO2 reading on the smartwatch and the companion app, the Zepp App.

Fitness Tracking Features

The Zepp Z comes with 12 active sports modes and 90 inactive activity modes that you can activate if needed. As it has built-in GPS+GLONASS, it tracks your outdoor activities accurately.

Unsurprisingly, the Zepp E does not have an onboard GPS. This makes this smartwatch your best sports companion during your various activities.

Like every Amazfit and Xiaomi wearables, it also has PAI (Personal Activity Intelligence) system onboard. It is a fitness score calculated based on your health metrics and fitness level like Fitbit Activity Zone Minutes

It Zepp Z has a waterproof rating of up to 5ATM. This means that you can use this smartwatch for swimming up to 50 meters underwater. Zepp recommends using fluoroelastomer strap while swimming. 

Battery Life 

A 340 mAh Lithium-ion polymer battery powers the Zepp Z. In typical usage, the company claims 15 days battery backup (I have to check it later). The ultra-saving mode with limited features can extend the battery life up to 30 days. The sophisticated magnetic wireless charger ensures fast and easy recharging. 

  • Always-on display
  • Find my phone
  • Amazon Alexa
  • ECG App.
  • Automatic Workout Detection.
  • It is compatible with android devices above 5.0 and Apple devices above 10.0 and above.
  • Multiple watch faces.
  • Schedule reminder.
  • Costly
  • No ECG available in the USA
  • Limited smart features

Final Verdict 

The Zepp Z smartwatch is a classic-looking smartwatch with very impressive health and fitness tracking features. It also offers plenty of health and fitness tracking features. 

However, it is pricy compared with other popular health tracking watches in the market. You can go for Apple Watch SE or Samsung Galaxy Watch Active 2, which is cheaper than Zepp Z.
