Xiaomi Watch Straps

Xiaomi Watch Straps — What Fits

Xiaomi's Wear OS smartwatch line — Watch S1, Watch S3, Watch S4 and Watch 2 — uses standard spring-bar lugs under the strap, exactly like most other Wear OS smartwatches on the market. That means any of the store's Xiaomi Watch straps swap on in seconds with a small lever, no proprietary tool or service center required. This hub covers the full current Wear OS lineup, and each model page below breaks down the exact case sizes and widths for that specific watch.

One thing worth flagging before you shop: Xiaomi's product range is bigger than just this Wear OS line. The company also sells the Redmi Watch series, the Mi Watch Lite, and a completely separate Xiaomi Smart Strap line covering the Mi Strap and newer Smart Strap models, and none of those three take a standard quick-release strap. They use a proprietary connector molded into the case itself rather than a spring bar, so no strap sold here will attach to them. If your device is a Redmi Watch, Mi Watch Lite or Smart Strap rather than a Watch S-series or Watch 2, see the dedicated section further down this page before ordering anything.

Which Strap Style Fits a Xiaomi Watch

All six of the store's quick-release styles fit the 22mm width used by most Xiaomi Wear OS watches. The 18mm width, used only on the smaller Watch S4 41mm case, currently has one style available.

Sport and Fitness

The Vornis silicone sport strap and Mavric braided loop suit Xiaomi's fitness-tracking focus, both wipe-clean and comfortable through workouts and sweat.

Office and Everyday

The Solin magnetic milanese mesh dresses the same watch up for the office, closing with a concealed magnet instead of a buckle. The Rovan magnetic silicone sport strap closes the same way, with a concealed magnet rather than a buckle. On the 18mm Watch S4 41mm, Rovan is the only style currently stocked.

Sleep and Light Wear

The Véllo and Voren nylon loop styles, 22mm only, are light enough for sleep tracking or all-day wear when you'd rather not notice the strap is there.

Sizing and Swapping Xiaomi Watch Straps

Every strap here uses the same quick-release spring bar as the strap that shipped with your Xiaomi watch. Press the small lever on the underside of the strap, slide it free of the lugs, then slide the new one in until it clicks on both sides — the whole swap takes under a minute with no tools beyond the strap itself.

Match the width to your model: 22mm covers Watch S1, S1 Active, S1 Pro, Watch S3, S2, Watch S4 47mm, S4 Sport, S5 46mm, and Watch 2, 2 Pro and Watch 5 (Wear OS). Only the Watch S4 41mm takes 18mm. Check the model pages below, or your watch's case size, if you're unsure which one you own.

Which Watches Don't Fit

The Redmi Watch line, Mi Watch Lite, and the Xiaomi Smart Strap line, including Mi Strap and newer Smart Strap models, do not fit any strap on this page. All three use a proprietary connector built into the watch case rather than a standard spring bar, so a quick-release strap bought here will not attach to them at all — not a looser or tighter fit, it simply will not click into the lugs. This mix-up is common because Xiaomi markets all of these product lines under one brand name, so it's worth double-checking which one you actually own before ordering.

Within the Wear OS lineup itself, watch the Watch S4 family specifically: the 47mm case takes 22mm, but the smaller Watch S4 41mm takes 18mm — the two sizes are not interchangeable despite sharing a model name. Check the model pages below to confirm your exact case before ordering.
