Xiaomi Watch S4 Bands (incl. S5)

Xiaomi Watch S4 Bands — What Fits

Watch S4 is Xiaomi's current Wear OS watch, sold in two case sizes plus the newer Watch S5, and — unlike Watch S1, S3 and Watch 2 — the two S4 sizes don't share one width. The 47mm Watch S4, S4 Sport and the 46mm Watch S5 all take a 22mm quick-release band; the smaller 41mm Watch S4 takes 18mm instead. Every size still attaches with a plain spring bar, so any xiaomi watch s4 strap on this page swaps on in seconds once you've matched the width to your case.

Check which case you have before ordering: the 47mm and 41mm versions look similar at a glance but need different band widths. For the rest of Xiaomi's current lineup, see the Xiaomi Watch Bands hub.

Which Band Style Fits a Watch S4

All six of the store's quick-release styles fit the 22mm Watch S4 47mm, S4 Sport and Watch S5. The 18mm Watch S4 41mm currently has one style available.

Sport and Fitness

On the 22mm case, the Vornis silicone sport band and Mavric braided loop suit S4's fitness-tracking side, both wipe-clean and comfortable through workouts.

Office and Everyday

The Solin magnetic milanese mesh and Rovan magnetic loop dress the 22mm S4 up for the office, closing with a concealed magnet instead of a buckle. On the smaller 41mm S4, the Rovan magnetic loop is the only style currently stocked at 18mm — a fitting match for the more compact case.

Sleep and Light Wear

The Véllo and Voren nylon loop bands, 22mm only, are light enough for sleep tracking or long days when you'd rather not notice the watch.

Sizing and Fitting a Watch S4 Band

Swapping the band takes the same steps regardless of case size: press the small lever on the underside of the band, slide it free of the lugs, then slide the new band's pins in until both ends click into place. It takes under a minute and no tools are needed beyond the band itself.

The detail to get right is width: 22mm for the 47mm Watch S4, S4 Sport and 46mm Watch S5; 18mm for the smaller 41mm Watch S4. A band cut for the wrong size won't seat in the lugs. Browse the full 22mm watch bands or 18mm watch bands ranges for more style options in either width.

Which Watches Don't Fit

All current Watch S4 and S5 sizes take a standard quick-release band, so there's no proprietary connector to worry about on this model line. The trap here is width, not compatibility, and it's specific to this model: the 47mm Watch S4, S4 Sport and 46mm Watch S5 need a 22mm band, but the smaller 41mm Watch S4 needs 18mm — the two S4 sizes are not interchangeable despite sharing a model name.

Separately, watch for Xiaomi's wider range: the Redmi Watch line, Mi Watch Lite, and the Xiaomi Smart Band line, including Mi Band models, all use a proprietary connector built into the case rather than a spring bar, so none of them take any band on this page. If your device is one of those rather than a Watch S4 or S5, nothing here will fit it.
