I designed this watch band as a replacement for my FitBit Charge 4 band after one of the clips snapped off of it. The pattern was created with the Charge 4 in mind, but should work with any generation of Charge from 3 on. The sleeve is worked flat and seamed to form a tube, with openings for the watch face and heart rate monitor. It uses a very small amount of any fingering weight yarn, making it a great way to use up all of your little bits for a variety of looks.

Sizing
The band size is adjustable to your needs with a simple equation to figure up stitches. It can be closed with a jump ring and bead, loop of chain stitches and a bobble stitch, or any other sort of clasp/closure that feels comfortable.

Gauge
Gauge for this pattern will depend on your specific yarn. You’re looking for a tight and tidy fabric as the stitches will stretch with wear.

Difficulty
This pattern is approachable for an advanced beginner or ambitious crocheter. You’ll need to know how to chain, single crochet, half double crochet, work in the front and back loops, and invisibly decrease in single crochet and half double crochet, both of which are outlined in the pattern.

Materials
18-20yd (4-6g) fingering weight yarn
