Xiaomi Watch S1 (Active) – chic smartwatch with a flawed system

With the Watch S1 and the Watch S1 Active, Xiaomi has introduced two new smart watches. They are intended to appeal not only to business users, but also to athletes.

Xiaomi has already released several smartwatches, including the Amazfit devices, which are usually quite cheap at discounters. The Xiaomi Watch S1 is another smartwatch under its own name. It not only offers numerous fitness modes, it also supports the measurement of heart rate, sleep quality and blood oxygen saturation. Two versions of the watch are available.

Xiaomi Watch S1 – the classic smartwatch.

The classic version of the watch – the Xiaomi Watch S1 – is equipped with a 1.43-inch AMOLED display with 466 x 466 pixels and 60 Hz, protected by sapphire glass. All models are water resistant up to 5 ATM and come with a strap made of leather and fluorocarbon rubber, and the straps can be changed quite easily, giving the smartwatch a new look again and again. Xiaomi ships the Watch S1 in black with a black fluorocarbon rubber strap and a black leather strap. The silver version of the watch comes with a gray fluorocarbon rubber strap and a brown leather strap. There are also over 200 custom watch faces to choose from to match.

Xiaomis Smartwatch ist sowohl mit Android-Smartwatches als auch iPhones kompatibel. Die Bedienung erfolgt über den Touchscreen oder zwei Knöpfe an der rechten Seite des Edelstahlgehäuses. Gleichzeitig unterstützt die Xiaomi Watch S1 aber auch die Bedienung über den Sprachassistenten Amazon Alexa. Mit der Uhr lassen sich Bluetooth-Anrufe tätigen, Benachrichtigungen von Apps empfangen oder Termine verwalten. Dank NFC-Support lässt sie sich auch zum bargeldlosen Bezahlen verwenden. Auch Dual-band GPS wird unterstützt.

Active version for athletes

Xiaomi has developed the Watch S1 Active especially for athletes. The display dimensions and the general shape are identical to the business version. However, the watch looks a bit more robust and less classy overall. Xiaomi specifies a runtime of up to 12 days in standby for both smartwatches. However, users can only reach this value when GPS and Bluetooth are turned off. The scope of delivery should also be noted because Xiaomi only includes a TPU/silicone wristband for the Active.

Fitness functions are equally supported by both watches. According to the manufacturer, a total of 117 different modes, 19 of which are professional modes, are available for selection. The Xiaomi Watch S1 (Active) is supposed to automatically recognize the type of sport currently being performed and switch to the appropriate mode. The training progress can be monitored via the app and the paired smartphone. Various health functions are also part of the watch’s repertoire. Among other things, users can monitor their sleep and stress levels and measure their heart rate and blood oxygen saturation (SpO2).

System from own development

Xiaomi did not mention which operating system the new watches run on. Thus, it can be assumed that the manufacturer relies on an in-house development instead of WearOS or the like. Unfortunately, this will probably also limit the compatibility with apps, which makes the smartwatch no real competitor to the Apple Watch or Samsung Galaxy Watch.

Both smartwatches are available in stores now. The Xiaomi Watch S1 costs 229 euros, the S1 Active is available for 179 euros.
