The Xiaomi Watch S4 was first introduced in late October 2024 in China, followed by a global release in March 2025. Unlike the Chinese market, where both Bluetooth and eSIM versions are offered, only the Bluetooth model can be found outside of China. Recently, Xiaomi also revealed a 15th anniversary edition of this smartwatch, which features the Xring T1, the company’s first 4G smartwatch chip. However, it seems Xiaomi still has more surprises in store for smartwatch enthusiasts.
New Variant on the Horizon
A recent leak indicates that a new version of the Xiaomi Watch S4 is on the way. Digital Chat Station reported that a model called the Xiaomi Watch S4 41mm has received certification in China.
This new variant carries the model number M2502W1, while the standard S4 is labeled as ‘M2425W1’, the eSIM variant is ‘M2424W1’, and the 15th anniversary edition is ‘M2426W1’. From its name, one can infer that this model is a more compact version of the Xiaomi Watch S4. The original model, along with the anniversary edition, has a case size of 47.3mm, which may be too big for users with smaller wrists.
Specifications Still Unknown
Currently, there are no specifics available about the Xiaomi Watch S4 41mm. It is expected to feature a smaller screen and a reduced battery capacity, likely leading to shorter battery life. Furthermore, it might come in different colors compared to its larger counterparts. However, it remains unclear if this model will also have an eSIM version that utilizes the innovative Xring T1 chip.
The Xiaomi Watch S4 41mm (currently priced at €139.28 on Amazon.de) is anticipated to launch alongside the Xiaomi Pad 7S Pro 12.5 and a special edition of the Xiaomi 15 Ultra.
