Xiaomi Watch S1 Straps (incl. S1 Active & S1 Pro)

Xiaomi Watch S1 Straps — What Fits

Watch S1, S1 Active and S1 Pro share the same 22mm quick-release lug, attached with a plain spring bar rather than a proprietary clip. That means any xiaomi watch s1 strap on this page swaps on in seconds, whichever of the three variants you own.

There's no width guesswork across this generation: S1, S1 Active and S1 Pro all take the same 22mm strap, regardless of the finish or sensor differences between the three. For the rest of Xiaomi's current lineup, see the Xiaomi Watch Straps hub.

Which Strap Style Fits a Watch S1

All six of the store's quick-release styles fit the 22mm Watch S1 case, so the choice comes down to how you plan to wear it.

Sport and Fitness

The Vornis silicone sport strap, the Rovan magnetic silicone sport strap and the Mavric braided loop suit S1's fitness-tracking side, all wipe-clean and comfortable through workouts.

Office and Everyday

The Solin magnetic milanese mesh dresses S1 up for the office, closing with a concealed magnet rather than a buckle.

Sleep and Light Wear

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

Sizing and Fitting a Watch S1 Strap

Swapping the strap takes the same steps on all three S1 variants: press the small lever on the underside of the strap, slide it free of the lugs, then slide the new strap's pins in until both ends click into place. It takes under a minute and no tools are needed beyond the strap itself.

Since every S1 variant shares the same 22mm case, there's no separate size to check before ordering — any strap on this page fits any S1, S1 Active or S1 Pro. Browse the wider 22mm watch straps range for more style options.

Which Watches Don't Fit

Watch S1, S1 Active and S1 Pro all take a standard 22mm quick-release strap, so there's no compatibility issue within this generation itself. The trap to watch for is elsewhere in Xiaomi's range: the Redmi Watch line, Mi Watch Lite, and the separate Xiaomi Smart Strap line, including Mi Strap models, all use a proprietary connector molded into the case rather than a spring bar, so none of them take any strap sold here.

If you're comparing S1 to a newer Watch S4, note that the S4 comes in two case sizes with different widths, 22mm and 18mm, unlike S1, which is 22mm across the board.
