The Xiaomi Watch S3 is a round, 47 mm smartwatch built around one idea you can see: the stainless steel bezel twists off and can be swapped for another style, so the same watch can look sporty on weekdays and dressier at a wedding. Underneath is a 1.43-inch AMOLED screen, dual-band GPS, Bluetooth calling, 150+ sports modes and a battery Xiaomi rates at up to 15 days of typical use. It runs Xiaomi HyperOS and pairs with Android and iPhone.

The Xiaomi Watch S3 interchangeable bezel
The bezel is the ring around the screen, and on the Xiaomi Watch S3 it is a separate stainless steel part that detaches with a twist. Xiaomi offers extra bezels such as Ocean Blue stainless steel, dual-tone ceramic, Chrome Yellow ceramic and a forged-carbon Rainbow version, each changing the watch’s character rather than only the watch face.
The watch ships with the standard black or silver bezel and a fluororubber strap. Additional bezels and straps are sold separately, so budget for them if the swap is the reason you are buying.
Display and build
The 1.43-inch AMOLED panel has a 466 × 466 resolution at 326 PPI, a 60Hz refresh rate and a maximum brightness of 600 nits, which is readable outdoors in most UAE daylight, if not under direct noon sun at full glare. The screen sits under Corning glass inside an aluminium alloy frame.
The case measures 47 × 47 × 12 mm and weighs 44 g without the strap. The fluororubber strap adjusts from 140 to 210 mm. Xiaomi makes the case in Silver and Black; the unit in this listing is shown in the product photos.
GPS and sports tracking on the Xiaomi Watch S3
Positioning uses L1+L5 dual-band GNSS across five systems: BeiDou, GPS, GLONASS, Galileo and QZSS. Dual-band reception helps most in the places single-band watches struggle, such as between tall towers in Dubai Marina or Business Bay, and Xiaomi says the antenna reception is improved over the Watch S1 Pro.
There are more than 150 sports modes, and the watch recognises six activities automatically: running, walking, rowing machine, elliptical, cycling and jump rope. The 5ATM rating covers pool swimming and showers, but not diving or high-speed water sports.
Health, calls and daily use
A 12-channel optical heart rate sensor with blood oxygen measurement, plus accelerometer, gyroscope, compass, barometer and ambient light sensor, tracks heart rate, SpO2, stress and sleep. These readings are wellness data, not medical diagnosis, so treat them as trends. Xiaomi does not list ECG or blood pressure measurement for the Xiaomi Watch S3.
Bluetooth 5.2 connects to your phone, and you can answer or reject calls from the wrist through the built-in speaker and microphone. NFC is listed in the specifications, though Xiaomi notes availability of NFC features varies by region. The portrait watch-face feature needs a phone on Xiaomi HyperOS.
Battery life, with its conditions
The 486mAh battery is rated at up to 15 days of typical use with an Android phone and 14.5 days with an iPhone, according to Xiaomi. Those figures assume the always-on display is off and heart rate is measured every 10 minutes without high-precision sleep tracking. With the always-on display enabled, Xiaomi’s figure drops to 5 days.
Heavy GPS use, frequent calls and bright screen settings will shorten it further, but most people will still charge the Xiaomi Watch S3 once a week or so rather than nightly. It charges on the included magnetic dock.
Who This Is Not For
Skip it if you want to leave your phone at home: the global Xiaomi Watch S3 has no LTE or eSIM, so calls and notifications need the phone nearby over Bluetooth. At 47 mm across it is also a large watch for slim wrists, and the bezel swap only pays off if you are willing to buy extra bezels.
People who need ECG readings or a medical-grade device should look elsewhere, since Xiaomi lists neither for this model. Divers should note that 5ATM is a swimming rating, not a diving one.
