Smartwatch band widths and attachment types: 395 watch references from 10 brands (Clipz-it, November 2026)

Summary. Band width and attachment type for 395 smartwatch references (model and case size) from 10 brands: Garmin, Apple, Samsung, Amazfit, Suunto, Huawei, Polar, Fitbit, Coros and Whoop. 22 mm is the most common width (155 references, 39.2 %), followed by 20 mm (104, 26.3 %) and 26 mm (61, 15.4 %); 18 mm (11, 2.8 %) and 24 mm (5, 1.3 %) are rare, and 59 references (14.9 %) use a brand-specific connector (Apple Watch, Galaxy Watch 8 and Ultra, Fitbit, Whoop, Garmin CIRQA). By attachment, 182 references (46.1 %) use Garmin QuickFit, 154 (39.0 %) a standard spring bar or quick-release pin. 31 watch series change band width with case size or version (e.g. Garmin Fenix 8: 20, 22 or 26 mm). Among Garmin 22 mm watches, 95 use QuickFit and 9 a quick-release pin: the same width does not mean the same attachment. Method. Export on 4 November 2026 of the Clipz-it compatibility table used by the clipz-it.com shop (30 attachment types, 417 rows, 415 unique names). Names were normalised and naming duplicates merged (e.g. 'Galaxy Watch4 (40 mm)' and 'Galaxy Watch 4 40 mm'; a generic entry without case size was dropped when the same watch is listed with its sizes and the same width), giving 395 references. Cross-check on a sample of 30 watches against manufacturer documentation (Garmin manuals, Samsung, Polar, Suunto, Amazfit and Coros support pages) or, where unreadable, several retailers: 28 are in the table and the width matches for 27; the Galaxy Watch 8, listed by Samsung with 20 mm bands, is kept as a separate attachment in the table. Limits. The table lists watches for which Clipz-it sells bands: it is not a market census and is not weighted by sales; Garmin is over-represented (236 of 395). Some naming variants remain. Apple Watch is counted as one connector (Apple's two band size groups are not encoded). For proprietary connectors the width column holds the connector name, not a lug width.
