Zepp is a well-known brand in the wearables industry. Its beginnings can be traced back to the year 2010 in Silicon Valley.

However, it is only following Huami’s acquisition that the company has begun to produce smartwatches. The initial attempt was Zepp E. This is a fashionable fitness watch that was released about four months ago. There are two different designs to choose from. One has an Applesque squarish appearance, while the other has a circular appearance. Both have an AMOLED display as well as Huami’s standard fitness and health features.

For the sequel, the studio has stepped up its game. Zepp Z, unlike its predecessor, only has a square iteration. It does, however, have a more quality Titanium body, as well as built-in GPS.

For the past few weeks, I’ve been walking, exercising, and sleeping with a Zepp Z strapped to my wrist. Continue reading for my thoughts on the book.

Review of Zepp Z: Design

Zepp Z is a good-looking guy. It’s certainly one of the most appealing clocks I’ve ever had the pleasure of trying out. You’ll want it because of the superb craftsmanship and high build quality.

The watch appears to be a high-quality conventional wristwatch at first sight. It also has a look and feel similar to the Garmin line, but with a more quality design. With Zepp Z, there aren’t many plastic or aluminum parts.

You may say that the watch manages to seem both sporty and stylish. Something you’d feel comfortable wearing to the gym, the golf course, the office, or on a night out.

Titanium construction

The watch consists of a single piece of Titanium alloy that has been brushed and polished. Zepp Z is extraordinarily light (40 grammes) and robust as a result of this. The Curved Watch Glass has a special NTC nanotech coating on top that makes it scratch resistant. The button and crown are both Titanium, and the rear is constructed of Ceramic.

All of this is held together by a genuine leather strap that feels and appears to be well-made. Having said that, I found the band to be a little stiff at times. It didn’t help that my ideal size fell right between two holes in the strap, forcing me to alternate between the looser setting while I wasn’t exercising and the tighter setting when I was running.

Which is better: the Fitbit Ionic or the Garmin Vivoactive 3?

A classic crown shape surrounds the sides, with engraved outer bezel ticks and numbers cut into the metal. The whole thing screams class.

The actual measurements of the watch are 45.945.910.75 millimeters. Despite the fact that it appears to be quite massive, it does not appear bulky. Plus, because it’s made of Titanium, you won’t even notice you’re wearing it. The watch is, nevertheless, more of a masculine than a unisex gadget.

The water-resistance is good. It has a 5 ATM rating, which implies it may be used down to a depth of 50 meters. Before leaping into the pool, ensure the leather band is removed. Water and leather don’t get along! For such, a fluoroelastomer or silicone strap would be preferable.

Exceptional presentation

The display on the Zepp Z is AMOLED. You wouldn’t expect anything less from something with such a high-end appearance. It sports a 1.39-inch display with a resolution of 454454 pixels at 326 pixels per inch. The maximum brightness is 550 nits. This makes the screen bright and clear, allowing you to read it in any light.

You can enable the always-on display option in the settings. According to Zepp, this will “severely” reduce battery life. When you enable this feature, the watch will cycle between full display and time-only mode when you aren’t using it. Alternatively, you can choose to have the display turned off by default or to use the always-on setting for a defined time period each day. These are the more energy-efficient options.

Watch faces are another option for personalization. On the gadget itself, there are a total of five saved. The smartphone app, on the other hand, contains about 50 more. They provide a wonderful balance of digital and analogue design options. Huami claims that you can even personalize the display with your own photo, although I haven’t tried it.

Individual cards can be accessed by swiping left and right on the home screen. For more information, swipe down on each one. Heart rate, PAI, activity, heart rate, weather, music, and smart assistants all have their own cards. Everything is incredibly smooth and functional. Huami utilizes the same operating system for its Amazfit range. Both the Zepp and the Amazfit watches use the same software and the Zepp smartphone app.

Swiping up from the home page will take you to the settings, while swiping down will take you to the notifications. The physical buttons on the right are used for the other manner of navigation. At first glance, there appear to be three of them. That is not the case, however.

The top button isn’t a button at all. It’s only there to make the object more appealing. I don’t think it’s clickable, so I don’t think a future software upgrade will make it work.

A shortcut to the complete menu is the crown in the middle. It basically functions as a button that takes you to the main menu. Then go through the options by rotating the crown. Exercises can be started quickly by pressing the bottom button.

Sensors for health and fitness

There’s the usual Amazfit tech under the hood. An accelerometer, Huami’s BioTrackerTM 2.0 PPG bio-tracking optical sensor, gyroscope sensor, geomagnetic sensor, capacitive sensor, air pressure sensor, and ambient light sensor round out the list of sensors.

Unlike the first version, the Zepp Z has GPS and GLONASS built-in. This is a crucial detail. When we tested Zepp E, one of our major complaints was the lack of a built-in GPS. In order to be considered a genuine sports tracker in 2021, a watch must feature built-in GPS.

Life of the battery

A large 340 mAh battery is said to provide 15 days of battery life on a single 2.5 hour charge. However, you’ll have a hard time achieving this figure. Especially if you use the always-on display, enable advanced health tracking, and occasionally utilize GPS. Apart from the always-on display, I accomplished most of these things myself and only needed to reach for the charger once a week for a short one-hour charge. For the average user, ten days is a reasonable expectation.

There’s also the option to keep it running for a month. However, this is in “extended battery-life mode,” which disables most of the additional features. However, if you run out of battery and your charger is nowhere to be found, you could fall back on it.

Features of the Zepp Z

Tracking your fitness and health

If you look at a couple Amazfit and Zepp watches, you’ll see how similar their features are. This is due to the fact that they both run on Huami’s proprietary operating system.

It appeals to me since it is straightforward, intuitive, and allows you to quickly locate information. The most crucial menu selections are merely a click or swipe away, and you aren’t bombarded with stats. When it comes to engaging with this watch, the learning curve isn’t too steep.

Zepp Z works effectively as a general health and fitness device. Step tracking, distance, calories, stress, heart rate, sleep, SpO2, and other functions are among the many available.

You’ll need to adjust the watch settings in the smartphone app to get the full range of health markers. This will allow you to raise the frequency of heart rate detection to a maximum of 1 minute, as well as enable automatic activity detection, heart rate alerts, all-day stress monitoring, and sleep breathing quality monitoring. Also, make sure the watch’s firmware is up to current.

The watch itself contains basic information on a variety of health and fitness indicators. Go to the Zepp smartphone app if you want to look beyond today’s statistics. It will take some getting accustomed to, unlike the watch’s operating system.

The software begins with a home screen that displays your step count as well as daily health and fitness highlights. For a more detailed view of activities, tap on almost any metric. Simply tap the symbol in the top right corner if you can’t locate the stat you’re looking for. This brings up a menu with all of your data’s shortcuts.

Choose the steps screen, for example, and you’ll be able to group data into totals for the day, week, month, and year. Below that, you’ll discover some health advice and insights. These are strewn over the app but aren’t intrusive, so you can ignore them if you want to.

The step tracking is adequate. When I compared it to a Garmin Forerunner on my other wrist, I saw that the count was slightly lower. But it’s nothing to get worked up about.

Huami actually prefers that you focus on PAI (Personal Activity Intelligence) above step count. It’s a more accurate reflection of your activity because PAI rewards you for pushing your heart to work harder. It’s important to keep the number above 100.

Sleep tracking is also effective. Your kip time will be divided into four categories: deep sleep, light sleep, REM sleep, and awake. It’s also possible to overlay your heart rate information on top of the sleep chart, which is a great addition.

The watch throws out a sleep score for those in a hurry. On a scale of 0 to 100, this rater rates the quality of your nightly sleep. Even that midday snooze will be detected by the watch.

In terms of insights, there’s an experimental sleep breathing quality score, as well as stats that I often choose to ignore due to their abundance. However, for those interested in learning more about their sleeping habits, there’s plenty to chew on.

When not exercising, the heart rate data is also of good quality. The figures on my Garmin watch largely matched the resting heart rate in the morning. According to studies conducted by the Cardiovascular Department of Peking University First Hospital, the PPG sensor monitors heart rates with an accuracy of 93.27 percent. The SpO2 sensor is one of the other health features. Because this is a one-time use device, there is no option to have it take readings automatically. When taking a measurement, make sure you’re sitting steady and not shifting your arm from its horizontal posture. I typically found that it took me two or three tries to get a successful reading.

You should be able to put your faith in the outcomes. Huami put the SpO2 accuracy to the test in the lab. In comparison to the measurement findings supplied by a medical SpO2 tester, the result indicates an average variance of only 1.67 percent.

Stress tracking, unlike SpO2, offers both a manual and automatic mode. I chose the latter, well aware that it would result in a slight reduction in battery life.

Tracking sports

The Zepp Z is designed to be a more serious sports tracker than the Zepp. There are 12 built-in sports modes and a total of 90 that may be engaged, as well as built-in GPS + GLONASS that can be used for a variety of activities.

I was excited to put the watch to the test as a runner. Just make sure the GPS software is up to date before using it. This will be done for you automatically using the smartphone app.

I discovered that Zepp Z consistently linked to the satellite signal and that the GPS measurements were accurate. Almost identical to Garmin’s. Disparities can arise in remote woodland areas and densely populated city streets, but this is to be expected.

While I was thrilled with the accuracy of the GPS, I was not so impressed with the accuracy of the heart rate monitor. When it works, it works exceptionally well. However, on one or two times, the exercise results would be drastically different. As a result, those numbers were very useless.

After reading other reviews, I discovered that there is a split between those who found heart rate tracking to be totally fine while activity and those who experienced problems.

This, I believe, has more to do with the leather band than anything else. It’s tough to secure the watch tightly against your wrist because it’s stiff.

When running, I recommend replacing the leather band with a silicone one for better results. Detaching the strap is simple and takes only a few seconds. In any case, you don’t want to get your lovely leather band sweaty!. In terms of statistics, you’ll find the normal assortment. This covers information such as average and maximum heart rates, cadence, stride, steps, pace, calories burned, and best pace. There are also a few graphs that go through some of these points in further depth.

Features that are clever

A brief glance at smart features concludes this evaluation. There’s no NFC, no built-in music storage, and nothing spectacular, but you get the essentials.

Incoming call notifications, app alerts, idle alerts, incoming SMS, emails, and goal notifications, as well as weather information, are all included. All of these can be adjusted individually with the smartphone app.

Incoming emails, for example, will display the sender and subject line. This is enhanced by the huge, bright AMOLED display. It’s a breeze to read messages and interact with the watch. You can’t, however, respond to notifications or do anything else.

For call alerts, the watch will vibrate during incoming calls and, if desired, display the caller’s phone number or name. There is also the option of adding a delay. You can enable a call alert somewhere between 3 and 30 seconds after the initial ring, for example.

Finally, you can also utilize voice controls to interact with Zepp Z owing to a built-in microphone. It allows you to operate the timepiece without using your hands to perform functions like controlling music, launching apps, initiating workouts, setting alarms, and much more. The smartphone app has a section that gives you a quick rundown of all the instructions you can use.

You’ll also be able to use Amazon Alexa. This feature was not available at the time of this review. When it’s ready, a long press on the crown will give you access to the function. Huami claims that Alexa connectivity will be available via a software update soon.

The final decision on Zepp Z

Zepp Z comes with a fantastic range of functions and a high-end design. You’ll be happy to wear it because the clock exudes elegance.

The watch performs admirably in terms of basic health and activity tracking. You’ll get the normal numbers as well as detailed sleep information, SpO2 monitoring, and stress tracking. All of this is linked to the Zepp app, which allows you to analyze long-term trends and get insights.

In terms of sports tracking, unlike its predecessor, the Zepp Z has GPS/GLONASS built-in. This is also quite effective.

When it came to recording my running heart rate, I had a few challenges. I believe these issues could be handled by exercising with a silicone band rather than a leather one. However, the Zepp collection requires considerable refinement before it can be considered a full-fledged sports watch replacement.

Which is better: the Fitbit Ionic or the Garmin Vivoactive 3?

Because of the high Titanium construction, the watch is quite costly. In that sense, it caters to a specific market segment. Users looking for a watch with stunning craftsmanship, high build quality, long battery life, and a robust set of health and fitness capabilities.

Zepp Z is available for $350 on It can also be found on Amazon (check price).
