Who makes watches for Xiaomi: production secrets and key suppliers

Xiaomi smartwatches and fitness bracelets have long been a symbol of affordable, high-functional technologies. But few people know that their development and production are not solely the responsibility of the company's engineers. In the Xiaomi ecosystem, there is a network of partners who specialize in wearable electronics. In this article, we will understand who makes the watch for Xiaomi, what technologies are used, and why it is important for the end user.

The secret to Xiaomi's success in wearables lies in its outsourcing strategy: it doesn't mass-produce watches on its own, it works with trusted manufacturers, and it cuts costs, speeds up the market, and focuses on software development. But who are these partners? And how do you identify them by device models? The answers are lower.

Huami: Xiaomi’s main partner in the production of watches

Xiaomi’s most well-known long-term wearables partner is Huami, which was founded in 2013 and was originally positioned as a developer of fitness trackers and smartwatches, and was behind the first mass-produced Xiaomi Mi Band devices and most of the Amazfit lineup.

Xiaomi and Huami are working together on the ODM (Original Design Manufacturer) principle: Huami designs and manufactures devices, and Xiaomi is marketing, selling and adapting firmware to its ecosystem. For example, the popular Xiaomi Mi Watch and Xiaomi Watch S1 models were created on the Huami platform, but with a proprietary interface MIUI for Watch.

• 🏭 Location: Huami's main plants are located in China (Hefei, Anhui Province).
• 🔧 Technology: Huami's own chips (e.g. Huami) Huangshan-1), Optical heart rate sensors, sleep monitoring algorithms.
• 📊 Market share: According to 2023, Huami has about 20% of the global fitness tracker market, largely thanks to a partnership with Xiaomi.

Interestingly, Huami also makes devices under its own brand, Amazfit, which often share similar technical specifications with Xiaomi models, but differ in design and software. For example, the Amazfit GTR 4 and Xiaomi Watch 2 Pro are built on the same hardware platform.

⚠️ Warning: If you see the Huami logo on the device's box, it doesn't mean the watch is fake.Many Xiaomi models have dual branding, especially in early installments.

Amazfit: a twin brand with common roots

Amazfit is a sub-brand of Huami, which was originally created as a premium alternative to the Xiaomi Mi Band line. However, over time, Amazfit has become an independent player in the market, offering devices with advanced functionality: from SpO2 monitoring to eSIM support.

Despite the division of brands, the technology base remains common.

• 🔄 Xiaomi Mi Band 7 and Amazfit Band 7 have the same display and sensors, but different software.
• ⚡ Xiaomi Watch S1 Active and Amazfit GTS 4 uses the same Apollo 4 processor.

The main difference between the two brands is software. Xiaomi uses MIUI for Watch or Zepp OS (in new models), while Amazfit runs on Zepp OS, a proprietary firmware with advanced features for athletes.

Other manufacturers: who else makes a watch for Xiaomi

Beyond Huami, there are other partners in Xiaomi’s wearables ecosystem, whose role is less visible, but equally important:

• 🛠️ Inventec is a Taiwanese company that builds some Xiaomi Mi Watch models (such as the Mi Watch Lite). HP Dell.
• 📱 BBK Electronics (owner of the brands Oppo, Vivo, OnePlus) – indirectly involved in the development of chipsets for Xiaomi smart watches through subsidiaries.
• 🔋 ATL (Amperex Technology Limited – battery supplier for most Xiaomi devices, including watches and bracelets.

It’s important to understand that Xiaomi doesn’t disclose the full list of partners, so some of the information is based on analysis of component shipments and patents, for example, in 2022, there was a data collaboration with Qualcomm to use Snapdragon Wear chips in premium watch models.

⚠️ Note: If you buy Xiaomi watches from unofficial sellers, check the manufacturer’s country in the device settings (Settings) → The phone. → Counterfeit products often indicate "Made in China" but have poor build quality.

How to determine the manufacturer of the watch model

To understand who exactly made your Xiaomi watch, just look at a few key details:

1. Name of model: 📌 If the name has "Mi Band" or "Watch S" in it, it's probably the Huami manufacturer. 📌 Models with the prefix "Amazfit" (for example, Xiaomi Mi Watch Color Amazfit Edition) also made by Huami.
2. Firmware: 🔄 MIUI For Watch - Huami or Inventec. 🔄 Zepp OS — Huami/Amazfit.

Serial number:

The first letters of the serial number (can be found on the box or in Settings → About the device) often point to the factory:

• 🔠 HM — Huami.
• 🔠 INV — Inventec.

For accurate identification, you can use the official authentication service Xiaomi. enter the serial number, and the system will show the country of origin and the date of release.

Why Xiaomi doesn’t make its own watches

The outsourcing strategy allows Xiaomi to focus on its core competencies:

• 📈 Marketing and sales: the company is perfectly able to promote products through its own channels (Mi Store, AliExpress, partners).
• 💻 Software: development MIUI, HyperOS and integration with Xiaomi ecosystem (smart home, smartphones, TV).
• 💰 Cost reduction: third-party manufacturing is cheaper than building your own lines.

In addition, partnering with Huami and other manufacturers gives Xiaomi access to off-the-shelf technology solutions, such as Huami’s health monitoring algorithms that have been developed over the years and tested on millions of users, and instead of building them from scratch, Xiaomi simply adapts them to its devices.

Another advantage is flexibility: If demand for a particular model falls, Xiaomi can quickly redirect orders to another factory without idling capacity, especially in an unstable electronics market.

💡

If you want to buy a Xiaomi watch with maximum ecosystem support, choose models on MIUI for Watch. Devices on Zepp OS (such as the new Xiaomi Watch 2) have limited integration with the Mi Home.

Quality of assembly: who is better at manufacturing

The quality of Xiaomi smartwatches depends not only on the manufacturer, but also on the specific model.

According to user reviews, the most reliable models are those made by Huami in the factories in Hefei, for example, Xiaomi Mi Band 7 and Watch S1 are less likely to have hardware defects than devices assembled in other enterprises.

But even the best manufacturers have a problem: in 2021, there was a batch of Xiaomi Mi Watch Lite with defective batteries that quickly ran out, and the problem was solved by replacing the battery supplier (from ATL to Sunwoda).

The future of production: what awaits the watch Xiaomi

In 2026-2026, Xiaomi plans to expand the line of smart watches, and this will entail changes in the production chain:

• 🌍 Production localization: part of the assembly can be moved to India and Vietnam to reduce logistics costs.
• 🔋 New battery suppliers: instead of ATL batteries can be used from BYD (Chinese giant that supplies batteries for Tesla).
• 🤖 AI and health: Huami is investing heavily in artificial intelligence algorithms for sleep and stress analysis, which will be integrated into new Xiaomi models.

Xiaomi is also expected to use its own chips (such as the Xiaomi Surge) in smartwatches to reduce dependence on external suppliers, a first step in this direction is the Xiaomi Watch 2 model with a Snapdragon W5+ processor, which was developed with the participation of Xiaomi engineers.

⚠️ Note: If you plan to buy a Xiaomi watch in 2026, look for models that support HyperOS. They will be better integrated with the company's new smartphones (e.g. Xiaomi 14).

💡

Huami remains a key partner of Xiaomi in the production of watches, but the company is gradually diversifying the supply chain to reduce risks and improve quality.
