Take off your current band and measure the gap between the two lugs (the small horns that hold the band) with a ruler, in millimetres. A 22 mm gap takes this band. If your gap is 24 mm, choose our 24 mm band instead. Check the spring bar. This band comes fitted with 1.8 mm quick-release spring bars, so no tools are needed: slide the small lever on the back of the band to fit or remove it. Measure your wrist. Wrap a tape measure — or a strip of paper you then lay against a ruler — snugly around your wrist where you wear your watch. The measurement should fall between 133 and 210 mm (5.2 and 8.2 in).
