Many users who choose wearable electronics often wonder if Xiaomi smartwatches that visually resemble the legendary Casio G-Shock or the classic digital models of the Japanese brand can be found. The desire to combine brutal, recognizable design with modern functionality of the smart gadget is understandable. The Mi Home ecosystem and the Amazfit sub-brand offer solutions that can satisfy this request, although direct copies with the Casio logo are not found here.
Unlike Japanese classics, which emphasize impact resistance and autonomy, Chinese devices rely on interactive screen, smartphone integration and health tracking. But the engineering mindset of designers often leads to form factors that are unmistakably read as “sports classics.” You don’t have to sacrifice style for technology if you pick the right model.
In this article, we will explore in detail which models are as close to the aesthetic of Casio as possible, how to customize their interface for maximum similarity and whether you should look for direct analogs at all. You will learn about the nuances of firmware, application compatibility and the real possibilities of trackers hidden behind the mask of retro design.
Why Casio Design is So Popular in the Wearable Electronics World
Casio aesthetics, especially the G-Shock and Edifice lineups, have become synonymous with reliability and male style. A square or rectangular body, large buttons (or imitations), contrasting digital font all create an image of a tool, not just jewelry. When users search for a “xiaomi watch as a casio,” they actually demand the gadget’s visual rigor and readability, which are often lost in modern round pancakes.
Chinese electronics manufacturers, including Xiaomi partners, are well aware of this trend: a rectangular display allows you to display more text, notifications and training data than a round one. In addition, flat faces are easier to protect from scratches and chips, which echoes Casio’s philosophy of impact resistance.
It's important to understand that there's no direct licensing collaboration between Xiaomi and Casio. You won't find a dual-branded device. The similarities are all achieved through industrial design and dial software. So when you choose a device, you're buying a Mi Wear or Zepp ecosystem, dressed in a familiar, square form factor.
Top Xiaomi and Amazfit models with G-Shock style design
If you’re looking for a device that looks like the Casio G-Shock at first glance, the Amazfit lineup, which is closely tied to Xiaomi’s ecosystem, often features massive, angular casings made of durable polymer, bringing them visually and tactilely closer to the Japanese originals.
One of the most striking models is the Amazfit T-Rex and its subsequent versions (Pro, 2).This tracker is certified to the military standard MIL-STD-810G, which brings it together with the concept of “unkillability” from Casio. Massive edges, large controls and a rough but functional look make it a direct competitor in the niche of sports electronics. The screen here is always on (or activated by movement), and the interface can be customized for a digital watch.
Another option is the Haylou Solar or the newer Haylou RS4 Plus models. Although they are often round-shaped, their digital dials and sports strap create the right mood. However, for maximum similarity, it is better to look at models with a rectangular display, such as the Amazfit Bip (Bip series).
- 🔷 Amazfit T-Rex 2 - massive body, 100+ sports regimes, military strength.
- 🔷 Amazfit Bip U Pro – Built-in GPS, rectangular screen, affordable price.
- 🔷 Xiaomi Mi Watch Lite – a square body similar to G-Shock, basic tracking.
- 🔷 Haylou Solar LS05 — budget version with a round case, but a digital retro style.
💡
The closest analogue of the G-Shock in the Xiaomi ecosystem is the Amazfit T-Rex series thanks to its angular design and increased body strength.
Customization of dials: turning Xiaomi into Casio
Even if the case does not fully replicate the angular shape of the Casio, choosing the right watch face can change the perception of the device by 90%. There are thousands of design options at Zepp or Mi Wear theme stores that mimic the classic electronic watch.
To achieve the most similarity, you need to look for dials with black backgrounds and bright segment numbers reminiscent of LCDs of the 80s and 90s. Often these themes are called “Digital”, “Retro”, “G-Style” or “Calculator”. Setting this design on a rectangular Amazfit Bip screen makes the device almost indistinguishable from classics at arm’s length.
The installation process is simple: open an app on your smartphone, go to your device profile, select Dials (or Watch Faces) and search for keywords. Many themes are free, but uniquely designed animation designs can require a symbolic payment. Remember that complex animated dials can consume battery power faster.
Where to look for rare dials?
You also need to consider the ability to customize the data you see, and in Casio style, it's important to be concise: time, date, and possibly day of the week, and remove the extra steps, pulse, and calories from the home screen if you want to keep the authentic look of a simple watch.
Comparison of functionality: what Xiaomi can do against Casio
The visual similarity is just the tip of the iceberg. The main difference lies inside. Casio (especially classic models) are famous for their autonomy in years and solar power (Tough Solar technology). Xiaomi and Amazfit smartwatches require charging every 7-20 days depending on the model, which is a significant trade-off.
But the functional gap is huge: where Casio shows time and alarm clock, the Chinese can measure blood oxygen (SpO2), track sleep phases, receive instant messenger notifications, and control music, and it's not just a chronometer, it's a full-fledged computer on the wrist.
Below is a table comparing the key characteristics of a typical G-Shock style representative and a modern smart tracker from Xiaomi:
| Characteristics | Casio G-Shock (classic) | Xiaomi / Amazfit (T-Rex/Bip) |
|---|---|---|
| Autonomy | 2-10 years (battery) | 7–25 days (Li-Ion) |
| Screen. | Segmental LCD (monochrome) | Color IPS/AMOLED |
| Notifications | Just a beep. | Vibration, text, calls. |
| Sensors. | Accelerometer (top) | Pulse, SpO2, GPS, Gyroscope |
| Waterproofing | 200m (often) | 5 ATM (50 m) |

If you are critically important to work hours without recharging for months, consider the hybrid models Casio G-SQUAD, which have a Bluetooth module, but retain the classic look.
Instructions: how to adapt the interface to retro style as much as possible
For your Xiaomi device to truly feel like an old-school gadget, a single picture change is not enough. You need to adjust the behavior of the system. Many users forget to turn off the unnecessary animations and smart features that give off the modern origin of the watch.
To start, go to your device settings via the Zepp or Mi Fitness app. Find the screen and brightness section. Set the screen to go down to a minimum (e.g. 10 seconds) to simulate the energy savings of older LCDs. If your model has Always On Display, you’d better turn it off or choose a black and white dial without colored elements.
Next, take the notifications. Leave only the most important ones: calls and perhaps SMS. Turn off the vibration for each step or goal if you are annoyed by the constant tactile response, not typical of the mechanics or simple electronics of the past.
☑️ Retro mode setting
It’s also worth turning off automatic pulse measurements if you’re not using a watch for sports right now, which not only saves you charge, but also removes the periodic lighting of green lights on the back cover, which gives off a smart device.
⚠️ Note: When installing third-party dials from unverified sources, make sure they are optimized for your firmware version.A faulty file can cause the watch interface to freeze, requiring a complete reset.
Compatibility issues and operational advice
Using Xiaomi devices in conjunction with iOS or older versions of Android may raise questions. To fully work the functionality, especially synchronizing new dials, requires a stable connection. If you need a watch like Casio primarily for sports, make sure that the model you choose supports the necessary metrics (for example, GPS for running outside).
Often, users find that the font on the dial looks "blurred" or fuzzy. This is due to screen resolution. On models with AMOLED matrix, black is perfect, which is critical for imitating old displays. On budget LCD screens, black can give gray, spoiling the impression. When choosing a model, consider the type of matrix.
Another important aspect is strength. Despite the appearance of the G-Shock, most Xiaomi models (except the T-Rex series) are not designed for extreme impacts. Glass screens are more vulnerable than Casio plastic lenses. Using a protective film or bumper case may be necessary if you plan to use actively.
- 🔸 Calibration: After purchase, be sure to calibrate the accelerometer after a known distance to make the steps more accurate.
- 🔸 Updates: Check firmware updates in the app regularly – they often improve sensor performance and add new dials.
- 🔸 Hygiene: Silicone straps popular in sports models require regular cleaning to avoid skin irritation.
⚠️ Warning: Do not attempt to disassemble the watch body yourself to "improve" protection or replace the battery. A leakproofness breach will instantly deprive the device of the declared moisture protection 5 ATM.
Final recommendations for selection
Choosing a Xiaomi Casio-style watch is about balancing nostalgia with tech. If you want a tool to survive in the woods for 10 years without maintenance, you'd better take the original Casio. But if you want a stylish accessory that helps you keep track of your health, answer your calls and still look brutal, the Amazfit T-Rex + retro dial is the perfect solution.
The wearable electronics market is changing rapidly, and manufacturers are increasingly turning to classic forms. Keep an eye out for new products, as even in the budget segment, models with metal casings and sapphire glass are appearing, which takes them to a new level of quality.
Don't be afraid to experiment with customization. Customization is the main advantage of a smartwatch over a regular electronics, and turn your gadget into a unique hybrid that combines the best of both worlds.
⚠️ Note: When buying used models, make sure that the previous owner’s account is untied. The Xiaomi ecosystem has a hard-to-repeal device, and password reset without access to the original account may not be possible.
