Same problem with F-105. Constant exposure to pool water seems to kill the wristband. I just got a black elastic band from a haberdashery store and experimented with it. My final solution is to cut a segment, seal both ends with superglue (to keep rubber strands fixed to the band structure) and fold over the pins and sew ends (used black dental floss since all I had at the time). Band is 20mm wide which is a tad too wide but works fine for me. It is very comfortable and I am never going back to a stock bands. They were selling the elastic band by the meter so I have enough for a decade or so.
