Which devices it works with

Rule: Apple Watch band — smaller cases — Fits Apple Watch cases of 38, 40 and 41mm, and the 42mm cases of Series 10 and later (Apple’s smaller band group). Apple's product page lists compatibility with 38mm, 40mm, 41mm and 42mm cases. (Apple's band article https://support.apple.com/en-gb/108908 groups older 42mm straps with 44/45mm; the current 42mm Sport Band's own page lists the small group.) Sold in S/M and M/L lengths as separate listings; this record uses Black S/M.
