Replacement of the dial on Xiaomi: from Mi Band to Watch S3 – full instruction

Replacing the dial on a smartwatch or Xiaomi fitness bracelet is a challenge that both beginners and experienced users face. The reasons can range from a banal desire to update the design to the need to repair mechanical damage (scratches, chips, glass detachment). However, not all dials are subject to replacement in the same way - the process depends heavily on the device model, its generation and even the firmware version.

In this article we will analyze all the current ways to replace the dial for the Mi Band lines (from 4 to 8), Xiaomi Watch (S1, S2, S3, Color, as well as devices under the Amazfit brand (GTR, GTS, You will learn what tools you will need, where to buy original and non-original parts, and how to avoid typical errors that lead to a breakdown of the display or loss of leakage of the case. AMOLED-Replacement of screens requires extreme caution.

Which dials can be replaced by yourself?

Not all Xiaomi smartwatches allow you to change the dial at home, but here are the key criteria by which you can determine the possibility of replacing:

• 🔧 Type of attachment: Mi Band 4/5/6 The dial is integrated into the case and does not remove without disassembling the device. S2 and Amazfit GTR 4 Modular system is used – the screen is separated from the frame.
• 🛠️ Case material: aluminum and steel models (e.g. Watch) S3) They often have removable glass, whereas plastic (like the Mi Band 7) do not.
• 🔋 Leakproofness: devices with protection 5 ATM (For example, Amazfit Bip U Pro require special glue when reassembled, otherwise water resistance will be lost.

Below is a table of compatibility of models with the possibility of replacing the dial:

If your model didn’t make it to the table, check its specifications on the official Xiaomi website or in the documentation. For example, the Amazfit T-Rex 2 has a non-removable dial, while the Amazfit Falcon allows you to replace the glass without disassembling the body.

Preparation for replacement: tools and materials

Before you start replacing, make sure you have everything you need. The absence of even one tool can lead to permanent damage - for example, trying to tamper with a glass knife instead of a mediator often ends in cracks in the display.

Here is the minimum set for most models:

• 🔥 Hair dryer or thermo-air station (for softening glue, temperature 60-80)°C).
• 🧲 Suction cups (diameter 30-40 mm, for removing glass).
• 📏 Plastic mediators (thickness 0.1–0.2 mm, for layer separation).
• 🧴 Clay. B-7000 or similar (for sealing after replacement).
• 🔍 Loop or microscope (to check contacts and cables).

For models with AMOLED-screens (e.g. Xiaomi Watch) S3) need to:

• 🛡️ Antistatic bracelet (so as not to damage the matrix with a discharge).
• 🧼 Alcohol and lilac-free wipes (for cleaning contacts).

⚠️ Note: If you replace the dial on the device with NFC (For example, Mi Band 7 Pro, after assembly, you may need to recalibrate the module through the Mi Fitness application.

Step-by-step: replacing the dial with the Xiaomi Watch S2

Consider the process using the Xiaomi Watch S2, one of the most popular removable glass models, and this instruction will also work for the Watch S3 and Amazfit GTR 4 with minor adjustments.

Step 1. Disconnect and heat the case

Turn off the watch and place it for 2-3 minutes under the hair dryer (70°C). This will soften the glue around the glass. Don't overheat - temperatures above 90°C can damage the battery.

Step 2. Take the glass out.

Attach the suction cup to the center of the dial and gently pull up. As soon as there is a gap, insert the mediator and slowly lead them around, separating the glass from the body. Do not force — if the glass does not respond, warm up the case again.

Step 3: Cleaning and installing a new dial

Remove the remnants of old glue from the body with alcohol. Apply a thin layer of B-7000 on a new perimeter dial (without touching the display!) and press it gently. Use a press (for example, a stack of books) for 10-12 hours to evenly distribute the glue.

Step 4: Checking the leakage

After assembly, test the watch for water resistance by placing it in a container of water for 1-2 minutes (no dipping buttons!). If bubbles appear, repeat sealing.

Replacement with Mi Band: Why is it more difficult?

Unlike smartwatches, fitness bracelets Mi Band are not designed to disassemble the user, OLED-The panel is glued to the board and protected by a thin plastic diffuser:

• 💥 Damage to the display plume (solding required).
• 🔋 Battery detachment (risk of short circuit).
• 🚫 Loss of leakage (bracelet will no longer be waterproof).

If you still need to replace the dial with the Mi Band 6/7, consider alternative options:

1. Buy parts on AliExpress (see "Mi Band 6 display assembly").
2. Contact the service center (the cost of replacement is ~ 1500-2500 rubles).
3. Use of protected covers (e.g. Spigen Tempo for Mi Band 7)

⚠️ Note: On the Mi Band 7 Pro and newer, the dial is combined with NFC-Replacing it at home will result in the loss of contactless payment function, requiring the module to be flashed in the service.

Where to buy original and unoriginal dials?

The choice of parts depends on the model and your budget: original dials guarantee compatibility but cost more, whereas non-original ones (like KXD or YCC) can have worse quality glass or glue.

The best places to buy:

When buying, pay attention to:

• 📋 Parts Article (for example, for Xiaomi Watch) S2 The original glass has a code MDY-007-21).
• 📦 Component (the set must have glue and mediators).
• ⭐ Seller rating (on AliExpress, choose with a score of at least 98%).

💡

Before buying, check if the new dial supports Always-On Display (AOD) function.Some non-original glass blocks it due to the wrong thickness.

Frequent Mistakes and How to Avoid Them

Even experienced users make mistakes when changing their dial, and here are the most common ones and ways to prevent them:

1. Overheating of the hull → Use a thermometer to monitor temperature (maximum 80)°C).
2. Getting glue on the display → Apply glue only on the edge of the glass with a thin brush.
3. Uneven pressing of glass → Use rods or heavy books for uniform pressure.
4. Ignoring leakproofness check → After assembly, be sure to test the watch in water (without dipping the buttons!).

The error with the break of the display plume is especially dangerous, it is typical for models with flexible cables (for example, the Amazfit GTS 2).

• Don’t pull the glass sharply – move the mediator smoothly.
• If the plume still broke off, do not try to solder it yourself - contact the service.

⚠️ Note: The Xiaomi Watch Color 2 often damages the light sensor (under glass) when replacing the dial. If the automatic brightness adjustment stops working after assembly, you will need to replace the sensor.

If you are not sure of your skills, it is better to contact the service.The cost of replacing the dial in official Xiaomi centers starts from 1800 rubles., Which is comparable to the price of a non-original spare part, but guarantees the safety of the device.

Alternatives to replacement: covers, films and program dials

If replacing the dial seems too risky or expensive, consider alternative ways to update the look of the device:

• 📱 Software dials: There are thousands of free and paid themes available in Mi Fit or Zepp apps. GTR 3 you can install animated dials with weather or pedometer.
• 🛡️ Protective glass: Tempered glass films (e.g. Spigen Glas.tR) EZ Fit) protect against scratches and give a new look. The cost is from 300 rubles.
• 👔 Silicone/metal cases: Cases with cutouts under the dial (for example, UAG Xiaomi Watch S2) mask damage and add protection against shocks.

For models with AMOLED-screens (e.g. Xiaomi Watch) S3) You can use dynamic dials that change color depending on the time of day or activity:

1. Official application Mi Fitness (section "Digitals").
2. Third-party services like Facer or WatchMaker (requires manual installation of.watch files).
