Withings ScanWatch Light Straps — What Fits
ScanWatch Light is Withings' slimmer, simplified take on its flagship hybrid watch: the same analog hour-and-minute hands with a small hidden display tucked into the lower half of the dial for step counts, heart rate and sleep summaries, minus the ECG electrodes found on the full ScanWatch. Its 37mm case takes an 18mm strap, which keeps shopping for a Withings ScanWatch Light strap straightforward — one width covers it. Every ScanWatch Light attaches its strap with a standard spring bar rather than a proprietary clip, the same mechanism used across the rest of the Withings Watch Straps range, so third-party straps click in exactly the way the original strap did.
For the 37mm ScanWatch Light there's no width guesswork the way there is on the wider ScanWatch or Steel HR lines: 18mm is the measurement this case needs, and every strap on this page is cut to that width.
Which Strap Style Suits ScanWatch Light
At 18mm, the store currently stocks one quick-release style: the Rovan magnetic silicone sport strap. It closes with a concealed magnetic clasp rather than a folding buckle, tucking flush against the wrist instead of leaving a raised bar of metal or plastic underneath the case. The silicone itself is flexible and lightweight, shrugs off sweat and water and wipes clean in seconds, which makes it an everyday and workout strap rather than a dress strap. The same Rovan strap is offered in 20mm for the larger ScanWatch and Steel HR cases, so ScanWatch Light isn't missing out by having a single option here.
Sizing and Fitting a ScanWatch Light Strap
Swapping the strap takes the same steps as any Withings quick-release strap. Press the small lever on the underside of the strap, slide it free of the lugs, then slide the new strap's pins into the same lugs until both ends click into place. The whole change takes well under a minute and needs nothing but the strap itself.
The 37mm ScanWatch Light takes the 18mm width shown on this page. The same strap also appears in our 18mm watch straps range, which gathers every 18mm quick-release strap we stock for slim-case watches.
Which Watches Don't Fit
ScanWatch Light itself has no exclusions: its 37mm case takes a standard 18mm quick-release strap rather than a proprietary connector. The trap worth flagging is cross-model confusion rather than compatibility. Withings sizes its straps by case diameter, not by product line, so an 18mm strap bought for ScanWatch Light will also fit any other Withings case of 39mm or under — the 38mm ScanWatch and ScanWatch 2, the 39mm Nova Brilliant, the 36mm Steel HR and Steel, and the 38mm Move — but it will not fit the larger ScanWatch 42mm, ScanWatch 2 42mm, Horizon 43mm, Nova 42mm, or Steel HR 40mm/Sport, all of which need the wider 20mm strap instead. If you or someone in your household also owns one of those larger-cased models, keep the two widths separate when ordering.
