Black Nike Apple Watch sports band, good condition. S/M Band Size (Band fits 130–180mm wrists) For reference, I was using this on an Apple Watch Series 3 and it also fits an Apple Watch Series 8 (41mm). Works with most versions of Apple Watch - from the Apple website: “This band should work with any Apple Watch Series 3 or newer case of the same size. The 41mm bands work with 38mm and 40mm cases.” ** BAND ONLY **
