How to measure: If you have a tailors measuring tape, then measure your wrist by tightly wrapping the tape where you would wear a watch. If you don't have one, grab a piece of paper, a pen, sticky tape, scissors and a ruler. ① Place one end of the strip where you would wear a watch, this will be the starting edge (use sticky tape to hold in place if needed). Wrap the strip tightly around your wrist, make sure it feels snug and doesn't slide. ② Use a pen to mark the strip at the place it overlaps. ③ Place the strip next to the ruler and measure the distance between the starting edge and the line you marked, do not round up now use the chart to determine the correct size.
